A comparative study of a structure and tribological properties of layers produced by Arc Spraying and Surfacing was done. A Fe-based Core Wire was used as a feedstock. Its distinctive feature is forming a metastable austenite type structure in a sprayed or surfaced layer. Applied energy of external load dissipates here in transforming of austenite to hard martensite. Methods of structural and phase analysis, abrasion and adhesive wear tests were performed to evaluate layers properties. An explanation of differences in properties between sprayed or surfaced layers was proposed. It was based on the analysis of influence of input energy parameters of Arc Spraying and Surfacing. |
