Реферат:
For the first time, the formation of coatings by detonation spraying (DS) of a binder-free tungsten carbide, WC, was studied. The coating phase composition was shown to depend on the O/C molar ratio in the oxygen-acetylene mixture used for the spraying. Along with WC, cubic carbide/oxycarbide WC1-xOy, tungsten semicarbide W2C and metallic W were present in the coatings formed at O/C = 0.9 and O/C = 1.0, indicating the formation of cermet composite coatings. When O/C was greater than 1.1, WC almost fully transformed into metallic tungsten in the coatings. The hardness of the cermet coatings was higher than that of the metallic tungsten-based coatings. During the coating formation, noticeable compression stresses accumulated in the deposited layers. These stresses do not lead to coating detachment or cracking: coatings with thicknesses of up to 500 μm retain their integrity.
