Abstract
The article presents the results of the development of technology for producing composite materials, in particular the production of clad powder materials for wear-resistant coatings. In the proposed method, a clad powder is processed by disintegrator with a new design of the working rotor. Powder particles consist of solid nuclei – core of micron size, surrounded by a cladding layer of soft components. A modified rotor design was used to develop a technology for producing clad powders with desired properties for example Stellite– Aluminum composition. The thickness of the cladding layer is 1.0–2.0 μm, and the firm adhesion of the hard and soft components required for the coating is confirmed. The necessary fraction of the composite powder 50–60 microns for gas-dynamic spraying has been achieved. The obtained experimental set of the plated powder was tested to obtain functional protective coatings using supersonic cold gas-dynamic spraying. Studies have shown that the adhesive strength of the coating was less than 75 MPa and the porosity less than 1.0%. The coating is recommended to protect some components and parts of precision machine-building and power engineering.
