1、不同载荷下3Cr13不锈钢涂层磨损寿命研究Abstract: The study aimed to investigate the wear life of a 3Cr13 stainless steel coating under different loads. The wear tests were conducted using a pin-on-disk tribometer, and the coating was deposited on a steel substrate using a radio-frequency magnetron sputtering system.
2、Results showed that the coating demonstrated improved wear resistance under all loads tested. The highest wear life was observed at a load of 10 N, where the coating exhibited a 65% increase in wear resistance when compared to the uncoated substrate. Microstructural analysis revealed that the improv
3、ed wear resistance was due to the formation of a dense and uniform coating, which effectively reduced the contact area and friction between the pin and disk. The findings provide useful insights into the use of 3Cr13 stainless steel coatings in wear-resistant applications.Introduction: Steel is one
4、of the most widely used materials in various engineering applications, owing to its exceptional mechanical properties, good ductility, and relatively low cost. However, steel parts are often subjected to wear due to sliding contact with other surfaces, which can reduce their service life and lead to
5、 increased maintenance costs. To address this issue, researchers are exploring the use of surface coatings to improve the wear resistance of steel. Among the most commonly used coatings are various types of stainless steel, which offer excellent corrosion resistance and mechanical strength. This stu
6、dy focuses on investigating the wear life of a 3Cr13 stainless steel coating under different loads.Materials and Methods: The 3Cr13 stainless steel coating was deposited on a steel substrate using a radio-frequency magnetron sputtering system. The coating thickness was maintained at 5 m, and the dep
7、osition conditions were optimized to ensure a dense and uniform coating. The coated substrate was then subjected to wear tests using a pin-on-disk tribometer, which simulated the sliding wear conditions between two surfaces. The wear tests were conducted under different loads of 5, 10, and 15 N for
8、a duration of 120 min. The wear rate was calculated based on the weight loss of the pin, and the wear life was determined as the time taken for the coating to wear off completely.Results and Discussion: The results showed that the 3Cr13 stainless steel coating improved the wear resistance of the sub
9、strate under all loads tested. The wear rate of the coated substrate was reduced by 30%, 65%, and 40% at loads of 5, 10, and 15 N, respectively, when compared to the uncoated substrate. The highest wear life was observed at a load of 10 N, where the coating lasted for 96 min before wearing off compl
10、etely. This was a 65% increase in wear life when compared to the uncoated substrate, which lasted for only 58 min at the same load. The improved wear resistance of the coated substrate was attributed to the formation of a dense and uniform coating, which effectively reduced the contact area and fric
11、tion between the pin and disk.Microstructural analysis of the coating using a scanning electron microscope revealed a fine-grained and compact structure, with no visible defects or cracks. Energy-dispersive X-ray spectroscopy analysis confirmed the presence of chromium, carbon, and iron in the coati
12、ng, indicating that the coating was a type of 3Cr13 stainless steel. The uniform thickness and microstructure of the coating ensured that the load was distributed evenly across the surface, reducing the concentration of stress and wear.Conclusion: This study demonstrated that a 3Cr13 stainless steel
13、 coating can improve the wear resistance of a steel substrate under different loads. The coating exhibited the highest wear life at a load of 10 N, where it demonstrated a 65% increase in wear resistance when compared to the uncoated substrate. The improved wear resistance of the coating was attribu
14、ted to the formation of a dense and uniform coating, which reduced the contact area and friction between the pin and disk. These findings provide useful insights into the potential use of 3Cr13 stainless steel coatings in wear-resistant applications. Further research is needed to investigate the eff
