Abstract
The surface of a metallic substrate is coated with wear-resistant material by depositing on the surface a layer of a mixture of a coating powder including a metallic carbide with powdery silicon and heating said layer by exposure to a source of high density energy to bring about simultaneous evaporation of said silicon and fusion of said coating powder with bonding to said substrate. A coating of high surface porosity can be obtained. The substrate may be a piston ring for heavy-duty internal combustion engines.
