Abstract

The article presents selected results of microstructural investigation of Ni-Cr-Re coatings deposited by means of plasma thermal spray. The substrate made of 16Mo3 chromium molybdenum boiler steel was sprayed with a powder material of Oerlikon Amdry 4535 80% Ni, 20% Cr, 20÷45μm, to which 1% of metallic rhenium was added. Rhenium are an alloying additive that improves the heat resistance of alloys, creep, and high temperature oxidation resistance. Alloys with the addition of rhenium are widely used in aviation and power industry. Metallographic microscopic examinations, microhardness tests and surface profilometry were carried out.

Keywords: Thermal spraying, protective coating, heat resistance, microstructure, Re addition, rhenium, coating
