The as-deposited and as-forged Ti60A titanium alloys are fabricated by the laser additive manufacturing technique, and the oxidation experiment under the temperature of 600-800 ℃ is conducted. The change laws of the weight increase and the microhardnesses of samples under different oxidation conditions are investigated. The results show that, the surface oxidation products of the as-deposited and as-forged Ti60A alloys mainly consist of TiO2 and Al2O3. The formation of the oxidation layers is caused by the combined action of the inward diffusion of the oxygen into the matrix and the outward diffusion of Al and Ti elements. Under the same experimental conditions, compared with those of the as-forged alloy, the weight increase of the as-deposited Ti60A alloy is smaller, the surface oxidation layer is thinner and denser, the diffusion depth of oxygen element is smaller, and the high-temperature oxidation resistance property is much better.
