| Abstract: | Ti 6Al 4V titanium alloy was laser surface alloyed with Al+ Nb. Using proper processing parameters, alloyed layers consisting of TiAl 3+TiAl+minor Al were obtained on the substrates. Results of oxidation test carried out at 900℃ in air showed that a dense and continuous α Al 2O 3 oxide scale, which effectively prevented the substrates from oxidation, could be formed on the surface of the alloyed layer. |
