Substrates coated with wear resistant layers and methods of applying wear resistant layers to same

摘要

A substrate (10) of a component is modified by coating the substrate (10) with an elastomer layer (14). The elastomer layer (14) is then modified by embedding hard particles (20) onto an outer side (18) of the elastomer layer (14). The hard particles (20) exhibit higher fractured toughness providing enhanced erosion protection. The elastic properties of the elastomer experience little reduction because the surface embedded particles (20) are located only at the outer side (18) of the elastomer layer (14). Therefore, the bond between the inner side (16) of the elastomer layer (14) and the substrate is not interfered with and the potential for electro-chemical corrosion and poor adhesion are not increased by the presence of the hard particles (20) as the hard particles (20) are located away from the inner face (16) between the elastomer layer (14) and the substrate (10).
