Study on Friction and Wear Behavior of Low Alloy Wear-resistant Steel
Introduction
Low alloy wear-resistant steel is a new type of wear-resistant material which has good mechanical properties and excellent resistance to wear and tear. The application of this material is mainly used in the production of high wear-resistant components and structural components for automotive, mining and other engineering industries. In recent years, low alloy wear-resistant steel has become increasingly popular in industry because of its superior performance in wear and friction. The study of friction and wear behavior of low alloy wear-resistant steel is necessary to better understand its potential applications and to design improved wear-resistant components and systems.
Friction and Wear Behavior of Low Alloy Wear-resistant Steel
The friction and wear behavior of low alloy wear-resistant steel is characterized by complex physical and chemical interactions between the surface layers of the material and the contacting surfaces. Generally, the wear rate of low alloy wear-resistant steel increases with increasing surface hardness and decreasing surface elasticity. However, the wear rate is also affected by the presence of organic layers on the surface, which reduce the coefficient of friction and wear rate. The wear rates of low alloy wear-resistant steel vary with factors such as surface roughness, contact pressure, temperature, and type of material.
Figure 1. Schematic of the three main types of wear on the low alloy wear-resistant steel surfaces.
Figure 1 illustrates the three main types of wear on low alloy wear-resistant steel surfaces, namely, adhesion wear, abrasion wear, and fatigue wear. Adhesion wear is caused by the formation of a layer of contacts between a hard asperity and a softer surface asperity, leading to deformation, plowing out and wear. Abrasion wear is caused by the removal of small pieces or chips of the material due to impact or rubbing against another surface. Fatigue wear is caused by the cyclic loading of the material, leading to the formation of cracks in the surface layer and eventual material failure.
Conclusion
In conclusion, low alloy wear-resistant steel is a promising material for engineering and automotive applications due to its good mechanical properties and high resistance to wear and tear. The wear behavior of this material is affected by a number of factors, including surface hardness, surface elasticity, organic layers on the surface, contact pressure, temperature and material type. The study of friction and wear behavior of low alloy wear-resistant steel is necessary to better understand its potential applications and to design improved wear-resistant components and systems.
