ELECTRO SPARK DEPOSITION OF TiB2 LAYERS ON Ti6Al4V ALLOY

Abstract

<p class="AMSmaintext">The electro spark deposition (ESD) method was used to create hard wear resistant layers of TiB₂ ceramic onto Ti6Al4V titanium alloy. Various deposition parameters and ways and condition 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 layers TiB₂ layer 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 using of protective argon atmosphere is vital for creation of pore free TiB₂ ceramic layer on Ti6Al4V titanium alloy.</p>
