However, there is still room for further research on this topic.Firstly, the present study only investigated the effect of surface treatment methods on the microabrasion-corrosion resistance of 316LVM stainless steel under laboratory conditions. Future studies can focus on studying the effect of surface treatment methods under different environmental conditions, such as temperature, humidity, and pH, which may affect the microabrasion-corrosion resistance of the material in practical applications.Secondly, the present study only studied the effect of carbonizing, nitriding, and carbonitriding surface treatment methods on the microabrasion-corrosion resistance of 316LVM stainless steel. Other surface treatment methods, such as electrochemical treatment, plasma treatment, and hybrid surface treatment, can also be explored in future studies.Thirdly, although carbonitriding surface treatment showed the best results in terms of microabrasion-corrosion resistance in the present study, the cost and complexity of the treatment process should also be considered. Future studies can investigate the cost-effectiveness of different surface treatment methods and optimize the process parameters to improve the efficiency of the treatment process.In addition to medical applications, 316LVM stainless steel is also widely used in other fields, such as the aerospace industry, automotive industry, and marine engineering. Therefore, the surface modification of 316LVM stainless steel has broad applications in various fields.In the aerospace industry, surface modification can enhance the microabrasion-corrosion resistance of aircraft components, such as turbine blades, engine parts, and fuel systems, which are exposed to harsh environmental conditions, including high temperatures, high humidity, and corrosive environments.In the automotive industry, surface modification can improve the durability and reliability of engine components, such as pistons, camshafts, and crankshafts, which are subjected to high mechanical and thermal stresses during operation.In the marine engineering, surface modification can enhance the corrosion resistance of marine structures and components, such as ship hulls, propellers, and offshore platforms, which are exposed to saltwater, waves, and environmental factors, such as UV radiation and temperature variations.ConclusionIn conclusion, this study investigated the effect of carbonizing, nitriding, and carbonitriding surface treatment methods on the microabrasion-corrosion resistance of 316LVM stainless steel. The results showed that carbonitriding treatment exhibited the best microabrasion-corrosion resistance among the three methods. However, further studies should be conducted to investigate the effect of surface treatment methods under different environmental conditions and optimize the treatment process parameters.
