One of the primary reasons composite materials excel in abrasion resistance is due to the hard and durable nature of the reinforcement fibers. For instance, carbon fibers are known for their high tensile strength and stiffness, which contribute to the overall durability of the composite. When these fibers are embedded in a tough polymer matrix, the resulting composite can withstand significant wear and tear. Moreover, the orientation and distribution of the fibers within the matrix play a crucial role in determining the abrasion resistance. Proper alignment and uniform distribution of fibers ensure that the composite can effectively resist abrasive forces from multiple directions.

In addition to the inherent properties of the reinforcement fibers, the matrix material also significantly influences the abrasion resistance of the composite. Polymer matrices, such as epoxy or polyester, are commonly used due to their excellent adhesion to fibers and their ability to distribute stress evenly. These matrices can absorb and dissipate energy from abrasive forces, thereby protecting the fibers from damage. Furthermore, advancements in polymer chemistry have led to the development of high-performance resins that offer superior abrasion resistance, even in harsh environments.

To understand why ceramics offer such remarkable abrasion resistance, it is essential to delve into their intrinsic characteristics and the science behind their durability.

Ceramics are composed of inorganic, non-metallic materials that are typically crystalline in nature. This crystalline structure contributes to their hardness, which is a critical factor in abrasion resistance. Hardness, in this context, refers to a material's ability to resist deformation and scratching. The harder a material, the more resistant it is to abrasion. Ceramics, such as alumina (Al2O3), silicon carbide (SiC), and zirconia (ZrO2), exhibit high hardness levels, often surpassing those of metals and polymers.

In addition to hardness, the microstructure of ceramics plays a pivotal role in their abrasion resistance. The tightly bonded atoms within the crystalline lattice of ceramics create a robust framework that can withstand significant mechanical stress. This microstructural integrity ensures that ceramics maintain their shape and functionality even under harsh conditions. Furthermore, ceramics possess a high melting point, which means they can endure extreme temperatures without losing their structural integrity. This thermal stability is particularly advantageous in applications where both abrasion and high temperatures are prevalent, such as in industrial machinery and cutting tools.

Another factor contributing to the exceptional abrasion resistance of ceramics is their low coefficient of friction. This property reduces the amount of wear that occurs when two surfaces come into contact. For instance, in applications like bearings and seals, the low friction of ceramic materials minimizes the wear rate, thereby extending the lifespan of the components. Moreover, ceramics are chemically inert, meaning they do not react with most substances they come into contact with. This chemical stability ensures that the material's surface remains intact and resistant to corrosive environments, further enhancing its abrasion resistance.

While ceramics offer numerous advantages in terms of abrasion resistance, it is also important to consider their limitations. One of the primary drawbacks of ceramics is their brittleness. Unlike metals, which can deform plastically under stress, ceramics tend to fracture when subjected to high impact forces. This brittleness can be mitigated to some extent by engineering composite materials that combine ceramics with other substances to enhance their toughness. For example, ceramic matrix composites (CMCs) incorporate fibers or particles within the ceramic matrix to improve their fracture resistance while maintaining high abrasion resistance.

In practical applications, the choice of ceramic material depends on the specific requirements of the task at hand. For instance, alumina is widely used in wear-resistant linings and cutting tools due to its excellent hardness and cost-effectiveness. Silicon carbide, on the other hand, is preferred in high-temperature applications because of its superior thermal stability. Zirconia is often selected for its toughness and resistance to crack propagation, making it suitable for applications where both abrasion resistance and mechanical strength are critical.

In conclusion, ceramics offer exceptional abrasion resistance due to their inherent hardness, robust microstructure, low coefficient of friction, and chemical stability. While their brittleness poses certain challenges, advancements in material engineering have led to the development of composite ceramics that address these limitations. As a result, ceramics continue to be a material of choice in various industries where durability and wear resistance are paramount.

With the increasing challenges in oil industry mining, higher demands are being placed on the longevity, corrosion resistance, and mechanical properties of sealing devices. Traditional rubber and plastic sealing technologies have struggled to meet these performance requirements, leading to the development of metal sealing technology. Initially utilized for sealing pipe string connections to withstand high pressure and temperature environments, metal sealing technology has evolved to be applied in micro-clearance sealing of oil and gas equipment and tools, such as through the use of metal sealing rings in valves, downhole tools, and pipe joints [ 1 ]. Research into the application of metal sealing components to seal units within oil and gas wells with large gaps began in the early 21st century. While progress has been made in China using superelastic metals as packer sealing components, most research remains concentrated in foreign countries [ 2 ]. Metal seals demonstrate exceptional durability under extreme conditions like underground high temperatures, pressures, and strong corrosion [ 3 4 ]. Compared to elastomer seals, metal-to-metal seals offer advantages, including superior high-temperature stability, higher rated pressure capacity, better chemical compatibility, erosion resistance, and recyclability. These features make metal seals more suitable for applications such as high-temperature/high-pressure oil/gas wells and heavy-oil thermal production [ 5 ]. Currently, there is limited research on material pairing surface modification for metal seals. Investigating how material selection surface modification between a metal piston sleeve affects seal device performance is particularly crucial. Surface modification of working materials is necessary to optimize corrosion wear resistance and increase strength. Modified surfaces can exhibit enhanced hardness and improved corrosion wear resistance [ 6 8 ]. Surface modification technology aims to improve part wear resistance by altering surface structure, depositing coatings, and changing surface composition. In this study, QPQ nitriding treatment and the DLC coating processes were selected variables to investigate their effects on friction wear properties of metallic surfaces.

As an advanced metal surface strengthening technology, QPQ nitriding combines nitriding and oxidation processes to improve the wear resistance and corrosion resistance of metal surfaces through salt bath composite treatment. This treatment technique minimizes workpiece deformation, so it has attracted wide attention in industrial applications [ 9 10 ]. It is found that 40Cr steel treated with QPQ has significant advantages in wear resistance compared to conventional quenching, low-carbon carburizing quenching, ion nitriding, hard chromium plating, and other treatments. The wear resistance of a 5Cr21Mn9Ni4N steel valve treated with QPQ is approximately twice as high as that of a hard chrome-plated valve [ 11 12 ]. The research of Guo Jie et al. [ 13 ] indicates that the friction coefficient and wear amount of QPQ-treated samples are reduced to varying degrees under dry friction, oil lubrication, and impact loads. Alberto et al. [ 14 ] found that QPQ technology can improve the wear resistance and corrosion resistance of materials, which is achieved by increasing the surface hardness and residual compressive stress of materials. The study of Khan et al. [ 15 ] showed that, compared with MoS2 coating, QPQ treatment can significantly improve the wear resistance of steel substrate. Additionally, this technology is compatible with a wide range of materials, has low production costs, and offers broad application prospects [ 16 ].

Diamond-like carbon (DLC), as a hard self-lubricating film material, exhibits exceptional mechanical and tribological properties, including high hardness, high elastic modulus, low friction, and superior wear resistance [ 17 19 ]. It has been widely applied across various engineering fields [ 20 23 ], including ceramic materials [ 24 25 ], metal materials [ 26 27 ], and soft materials [ 28 ]. Research indicates that the DLC coating can significantly enhance the surface hardness and corrosion resistance of alloy substrates. Seyed Elias et al. [ 29 ] found that the DLC coating effectively increases the surface hardness of alloy matrices and reduces their friction coefficient from 0.2 to 0.13. Furthermore, Mannan et al.&#;s [ 30 ] research findings demonstrate that under oil lubrication conditions, among two paired auxiliary materials of steel and DLC, the DLC/DLC combination exhibits the smallest friction coefficient, followed by steel/DLC, while steel/steel shows the largest value. This indicates that the DLC coating can effectively reduce friction coefficients.

Based on our newly developed metal sliding seal, which has been proven to have a good sealing effect, this study aims to provide a more reliable and efficient material selection scheme for oil drilling tools by comparing the pairing relationship between piston and sleeve materials and two different surface modification methods, DLC coating and QPQ nitriding treatment. This study will provide a more reliable and efficient material selection scheme for oil drilling tools and seeks to extend the reliability and service life of the equipment. Additionally, it will offer theoretical support for the design and optimization of oil drilling seals.
