THERMAL SHOCK RESISTANCE OF COATINGS FROM A POWDER CoCrAlY OBTAINED BY MULTICHAMBER GASDYNAMIC ACCELERATOR ON THE SURFACE OF HIGH TEMPERATURE ALLOYS

Abstract

One of the most important challenges in industry is to reduce consumption of power and materials, and decrease pollution of atmosphere with greenhouse gases and fumes. The purpose of this study was to develop energy-saving technologies and getting heat-resistant protective coatings on the surfaces of high-temperature alloys. The coatings of powder CoCrAlY were deposited to the substrate from a heat-resistant alloy by using a detonation technology. Studies of thermal shock resistance of coatings with two types of cooling mode have been conducted. It is shown that the application technology provides resistance of coatings to thermal shock, which increases the life cycle of the components of heat-resistant alloys.
