Structure and Physical Properties of High Entropy Coatings on Surfaces of Weapons and Military Equipment Parts

Abstract

The method of spraying CGDN coatings we propose is universal for repairing military equipment in the field. We carried out the method using a Dimet-425 installation and an IPG Photonics laser. The increase in heat resistance and adhesion of the coated sample relative to the uncoated sample is explained by the fact that the modified surface layer of the sample is a transition layer that has a sharp boundary with the base material or transition zone, consisting of a diffusion zone and a thermal-affected zone. The characteristic adhesion value obtained for CGDN coatings is 20 - 80 MPa, and the powder utilization rate reaches 50 - 80%
