A thermal nitridation treatment was performed on Zr-Ti-Al-V alloy to enhance its properties. The composition, thickness, corrosion resistance, hardness and wear resistance of the thermal nitridation film were studied, and it was found that the film had good corrosion resistance, hardness and wear resistance.
In this work, a thermal nitridation treatment was carried out on the new high-strength and toughness Zr-Ti-Al-V alloy. The composition, thickness, corrosion resistance, hardness and wear resistance of thermal nitridation film were systematically studied. From the extracted results, it was demonstrated that the thermal nitridation film was mainly composed of nitrides and oxides of Zr and Ti, while the presence of the Al2Zr compound phase was also found. The hot nitrided samples were better resistant to corrosion than the matrix in 3.5% NaCl solution. The hardness and wear resistance of the hot nitrided samples were also improved.
