ELECTRO SPARK DEPOSITION OF TIB2 LAYERS ON TI6AL4V ALLOY

Abstract

The electro spark deposition (ESD) method was used to create wear resistant layers of TiB2 ceramic onto Ti6Al4V titanium alloy. Various deposition parameters and ways of deposition were employed in this study. It was showed that the TiB2 layer on Ti6Al4Vcan be successfully created even using hand operating ESD equipment. Then, the microstructures of the obtained TiB2 layers on Ti6Al4Vwere investigated using scanning electron microscope. Finally optimal conditions of the electro spark deposition were determined with respect to the obtained microstructure. It was also demonstrated that by using of multiple runs dense layer of almost pore free TiB2 ceramic layer on Ti6Al4V titanium alloy can be successfully prepared.
