Composition, structure and properties of electric spark and laserspark ZrB₂-containing coatings on titanium alloys

Abstract

Composition, structure and microhardness of ZrB₂-containing electric spark and laserspark coatings on titanium alloys depending on the deposition duration and the treatment regimes have been investigated. At initial period of the coating deposition, globular structure of the surface was formed due to different wettability of the spark coating components by substrate material. Microhardness of the laser-spark coating reaches ~22 GPa. Full text download
