High-Speed Thin Layer Coating

Article Preview

Abstract:

The paper presents the results of the studies devoted to justification and development of methods and means of high-speed thin layer coating. It outlines the layer conditions formation, as well as the requirements for the individual components and surfacing installation assemblies. The following equipment items are designed and manufactured for the implementation of the developed coating processes: surfacing rack, feeding device rotating filler, surfacing head-die and others. The paper presents the completely temperature pattern detailed calculation program with differential-difference scheme-line obtained from a combination of explicit and implicit schemes. The mechanical properties, residual stress, fatigue strength, hardness and microstructure of the coating, etc. have been undertaken as well. The paper recommends the technology to restore worn surfaces of the cylindrical parts with little wear and tear (up to 0.3 mm) and to impart special physical and mechanical properties of the manufactured machine parts surfaces.
