Development of Parameters Optimization Technology for Obtaining Composite Materials and Coatings with Shape Memory Effect
The paper studies the technology of producing composite materials and coatings by means of high-velocity oxygen-fuel spraying (HVOF) in a protective atmosphere. We have developed technologies for the formation of nanostructured surface layers made of multicomponent materials in the conditions of high-velocity oxygen-fuel spraying in order to improve operational properties and expand functional capabilities of engineering products. We optimized technological parameters and constructed nomograph of the process. We described a modernized GLC-720 unit which implements the resource-saving technology for the formation of nanostructured surface layers on cylindrical details, and makes it possible to produce HVOF in a protective atmosphere and thermomechanical processing in a single technological cycle.
