Plasma Reinforced Ceramic Coatings,
Abstract
The introduction of metal reinforcement (W, Mo) into the plasma ceramic Al2O3 coatings results in the following: increased strength of their adhesion to the substrate and a prolonged service life due to a firm contact ensured by welding the reinforcing elements; decrease in the thermal expansion coefficient (KTR) of coatings and a decrease in the difference in the KTR values of the substrate and coating, facilitating a decrease in the developing thermal stresses and an increase in the thermal stability of coatings; increased thermal conductivity of coatings, which leads to the equalization of temperature fields, decrease in thermal stresses and, consequently, to increased thermal stability of coatings.
