Abstract
The paper analyses the technology of plasma spraying of composite coatings onto a metal substrate. Al2O3-based ceramic materials with the addition of metallic and plastic components were used as the starting material. The subject of our research was investigation of the formation and certain properties of the above-mentioned composite coatings prepared using plasma-spray equipment with water arc stabilization. It is well known that such equipment shows high thermal capacity and temperature of the plasma jet. With this in mind, our main goal was to verify the behaviour of the plastic and metallic components of the powder in the process of forming the composite coating by plasma spraying. The obtained results have shown that plasma spraying with water arc stabilization is suitable for the formation of composite coatings of the ceramics-plastic and ceramics-metal types. These coatings show high quality and are suitable for many practical applications.

Key words
