Abstract
Research results are given for study and use of cermet electrode materials, intermetallics, materials based on MAX-phase and ceramic materials with a nanosize structure for application of protective coatings by electric-spark alloying and electric-arc hardfacing on a metal substrate. The microstructure and properties of the alloy and hardfacing layers formed, and the nature of substrate material interaction with SHS-electrodes are studied, and comparative tribological tests are performed for coating strength. Some results of industrial testing of the materials developed are provided.
