Abstract: In order to study the radial micro-motion behavior of TiN coating, a friction test was carried out utilizing a pin-on-disk tribometer. The test was conducted with normal loads ranging from 5 N to 20 N and sliding velocities ranging from 0.1 m/s to 0.5 m/s. The results showed that TiN coating exhibited better friction and wear resistance compared to the substrate material. The radial micro-motion of the coating was measured and analyzed using a high-resolution nsor, indicating that the TiN coating has better radial stability and less relative motion.

Introduction: TiN coating is widely ud in various engineering fields due to its excellent mechanical properties, such as high hardness, wear resistance, and corrosion resistance. In tribological applications, the evaluation of the radial micro-motion behavior of coatings is one of the key factors affecting the friction and wear performance of the coating. In this study, we investigate the radial micro-motion behavior of TiN coating through friction tests and high-resolution nsor measurements.
Experimental Procedure: The friction test was performed using a pin-on-disk tribometer with a normal load ranging from 5 N to 20 N and sliding velocities ranging from 0.1 m/s to 0.5 m/s. A TiN-coated pin was ud as the sliding counterpart while a stainless steel (SS304) disk was ud as the substrate. The surface roughness of the substrate was Ra = 0.2 μm. The wear track and friction coefficient were measured using a 3D profilometer and a force nsor, respectively.ubi
The radial micro-motion of the TiN coating on SS304 was measured using a high-resolution displacement nsor (Nikon LK-CLM1). The nsor was placed on the surface of the coating and the relative motion between the coating and the substrate was measured during the friction test.
Results and Discussion: The friction coefficient of TiN coating on SS304 decread with increasing normal load and sliding velocity. At a normal load of 20 N and a sliding velocity of 0.5 m/s, the friction coefficient was 0.32. The wear volume of the coating was much lower than that of the substrate, indicating that the TiN coating had better wear resistance.

The radial micro-motion behavior of the coating was analyzed using the high-resolution nsor. The results showed that the radial deviation of the coating was less than 0.2 μm, indicating that the coating had better radial stability. The relative motion between the coating and the substrate was also measured, and the results showed that the radial micro-motion of the coating was less than 60 nm, indicating that the coating had less relative motion.
Conclusion: In this study, we investigated the radial micro-motion behavior of TiN coating on SS304 using friction tests and high-resolution nsor measurements. The results showed that TiN coating exhibited better friction and wear resistance compared to the substrate material. The coating had better radial stability and less relative motion, indicating that it had a better capability to withstand external forces and to maintain its original shape. The results provide valuable insights for the design and application of TiN coatings in tribological systems.Furthermore, the study demonstrated the significance of the radial micro-motion behavior of coatings in tribological systems.

n with the substrate is important for maintaining its functional and protective properties. A coating with poor radial stability and excessive relative motion may result in accelerated wear or even failure of the protective layer, leading to rapid degradation of the substrate material.
The results of this study have implications for the design and optimization of coatings for tribological applications. Coatings that feature better radial stability and reduced relative motion could be developed and optimized for enhanced wear resistance, reduced friction coefficient, and longer rvice life. The u of high-resolution nsors to characterize the radial micro-motion behavior of coatings can provide valuable insights into the tribological performance and optimization of coatings for various applications.

al to inform the development of new coatings with enhanced properties for various industrial applications.One possible approach to improving the radial stability of coatings is to modify the coating composition or structure. For example, the addition of a cond pha or a nanostructure to the coating can enhance the coating's stability and improve its tribological properties. Similarly, optimizing the deposition process and parameters can improve the coating's adhesion and reduce its susceptibility to deformation and wear.
Another potential avenue for improving coating performance is through the u of multi-layered coatings or hybrid coatings. By combining different materials or structures, the coatings can provide a range of functional properties, such as enhanced wear resistance, improved hardness, and reduced friction. For example, a TiN coating could be combined with a DLC (diamond-like carbon) layer to create a hybrid coating with superior properties.全国大学生四六级官网
