It is well known that the abrasion wear-resistance of conventional WC–Co cemented carbides and other hard materials depends mainly on their hardness, and the dependence is represented by a relatively narrow band [1].In turn, the dependence of hardness on fracture toughness for WC–Co materials having different …
Materials such as nitrides, carbides, carbon-based, oxides and borides [4], are widely used in hard coating technology for their outstanding mechanical and tribological properties. Besides the high hardness and wear resistance, excellent chemical stability and oxidation resistance in severe environments are also regarded as the recurrent features.
Abrasion resistance of a coating is related to a coating's ability to resist wear or deformation due to erosion or impact. The better the abrasion resistance of coating, it provides better and long-term …
Wear resistance of metals is directly related to their hardness, and the degree of penetration of the particle is given by w _ load on the particle Hy hardness of the surface Wear volume (V) is given by V = (w/Hy)AL (2) where A is the cross sectional area of the groove and L is the length tra versed.
Wear is the damaging, gradual removal or deformation of material at solid surfaces. Causes of wear can be mechanical (e.g., erosion) or chemical (e.g., corrosion ). The study of wear and related processes is referred to as tribology . Wear in machine elements, together with other processes such as fatigue and creep, causes functional surfaces ...
