| description | •The dependences of the rate of weight gain and size of the oxide particles on the oxidation temperature were investigated.•The mechanism of oxidation resistance enhancement of Ti6Al4V titanium alloy induced by laser shock processing was studied.•The dense Al2O3 layer formed by laser shock processing was the main factor of oxidation resistance enhancement.
The high-temperature oxidation resistance of laser additive manufactured (LAM) Ti6Al4V before and after laser shock processing (LSP) was investigated. The samples were oxidized at 400−800 °C for 1−50 h in air. The results revealed that the rate of weight gain of the Ti6Al4V fabricated through LAM decreased, and LSP had a positive effect on increasing the oxidation resistance. At an oxidation temperature of 700 °C, an aluminum-rich layer was observed in the cross-section before LSP. After LSP, the aluminum-rich layer changed to three layers. The aluminum-rich layer prevented the diffusion of oxygen, which improved the oxidation resistance of the Ti6Al4V. |
