Theoretical fundamentals and technologies of deposition of wear resistant eutectic coatings

Abstract

In this work we propose a new view to natural composite materials - multicomponent eutectic alloys, which may be used for broad variety of applications - manufacturing and recovery of turbine blades, stator vanes, metallurgical furnaces, quick closing equipment, cutting tools etc. These wear resistant materials may be used for manufacturing or modification of heavy duty components, so significant part of current work is devoted to overview and development of efficient coating deposition technologies - plasma and gas spray, laser alloying and surface engineering. We also evaluate the effects of deposition processes parameters on microstructures, mechanical properties and wear resistance of coatings being investigated.
