Metastable Austenite Type Core Wire for Arc Spraying – Modeling of Heat Transfer in End Face and Coating Structure Analysis

Analysis of melting mode of core wire at Arc Spraying helped to explain a possibility of incomplete fusion of a charge of a core wire. Influence of physicochemical parameters of feedstock and atomization modes was established. Analysis results helped to develop a metastable austenite type Core Wire for Arc Spraying of good wear resistance. Applications results are shown.
