The coatings are categorized into plasma-sprayed ceramic wear-resistant coatings and supersonic flame-sprayed carbide ceramic coatings.

The ceramic materials used in plasma coatings are primarily a series of oxide ceramics such as aluminum titanate/chromium oxide. These materials boast exceptional properties such as high hardness, excellent corrosion and heat resistance, and a low coefficient of friction. Consequently, the coatings produced by this method exhibit outstanding and stable wear and friction reduction properties.

Metallic ceramic coatings are composite materials with nickel-chromium and cobalt as the metallic phase and tungsten carbide, chromium carbide, and other hard ceramic phases, characterized by high hardness and good toughness.
