- Abstract
The results of a study of the effect of temperature on the thermophysical characteristics of cermet coatings formed by carbo-vibro-arc hardening (CVAH) are presented. It was found that with an increase in temperature from 25 to 970°C, the coefficient of thermal conductivity λ of the coatings varies in the range from 18.1 to 24.0 W/(m·K), the specific heat from the coatings varies in the range from 560 to 895 J/(kg·K), and the thermal diffusivity coefficient a practically does not change, its average value is 5.1 × 10–6 m2/sec. The results of the research can be used to simulate the formation of high-quality metal-ceramic coatings by the CVAH method.
