Impact abrasive wear performance of new martensitic wear-resistant steel

Martensitic wear-resistant steel is an alloy steel produced by heat treatment. It is composed of iron, chromium, and molybdenum, which makes it a highly abrasion-resistant material. However, conventional martensitic alloys are susceptible to material softening at temperatures above 500 degrees Celsius due to the formation of carbides. Therefore, to improve the wear-resistance of martensitic alloys and extend their useful applications at high temperatures, new martensitic wear-resistant steels have been developed. This article reviews the impact abrasive wear performance of new martensitic wear-resistant steels.
    
Impact Abrasive Wear Performance
Impact abrasive wear is a type of wear that occurs when an abrasive material is accelerated in order to strike a surface. This type of wear typically results from particular construction activities, such as drilling and cutting. Impact abrasive wear can occur on all forms of material, including metallic and non-metallic surfaces. As such, it is important to understand the wear performance of martensitic alloys in order to ensure their longevity and performance in potential applications.
    
The impact abrasive wear performance of new martensitic wear-resistant steels has been studied by many researchers, who have noted that the material exhibits excellent wear resistance. Studies have been conducted in laboratories using a variety of test methods, including the pin-on-disc method, the three-body wear tester method, and the dry sliding wear tester method (Fig. 1).
    
These studies have shown that the combination of alloying elements in new wear-resistant steels significantly improves their wear performance on impact. This can be attributed to the fineness of the microstructure in the materials, as well as the high hardness of the alloy. Furthermore, new martensitic wear-resistant steels have been shown to improve abrasive performance in of high temperature environments due to their increased oxidation resistance and higher strength-toughness ratios.
    
Conclusion
New martensitic wear-resistant steels have been developed in recent years, showing great promise for their use in high temperature applications. Studies have shown that the combination of alloying elements in these new wear-resistant steels significantly improve their wear performance on impact, making them suitable for many operations involving abrasive wear. As such, these materials represent a cost-effective solution for a wide range of applications.
