Effect of heat treatment on the high-temperature wear resistance and oxidation behavior of laser powder bed fusion-manufactured Inconel 718 alloy

The HT specimens demonstrated better wear resistance than the as-built LPBF specimen, as evidenced by a reduction in the average coefficient of friction from 0.74 to 0.69 after heat treatment.经热处理（Heat Treatment, HT）的试样展现出优于原始成形激光粉末床熔融（Laser Powder Bed Fusion, LPBF）试样的耐磨性能，该性能优势可通过热处理后平均摩擦系数从0.74降至0.69得以验证。
