中文摘要：
A 穿抵抗金属间化合的合金由 TiNi 主要树突和 Ti2Ni 矩阵组成被融化免职生产的激光制作过程。穿 Ti2Ni/TiNi 的抵抗合金在磨料上被评估在不同负担下面在房间温度穿测试者。结果证明金属间化合的合金承受更多的磨料穿攻击在下面低比高铬的铸铁穿 7， 13 和 25 N 的测试负担。然而，金属间化合的合金展览更好穿抵抗在下面穿 49 N 的测试负担。磨料融化免职 Ti2Ni/TiNi 合金的激光穿被管理由微切、耕作。TiNi 的 Pseudoelasticity 在贡献磨料起一个活跃作用穿抵抗。
英文摘要：
A wear resistant intermetallic alloy consisting of TiNi primary dendrites and Ti2Ni matrix was fabricated by the laser melting deposition manufacturing process. Wear resistance of Ti2Ni/TiNi alloy was evaluated on an abrasive wear tester at room temperature under the different loads. The results show that the intermetallic alloy suffers more abrasive wear attack under low wear test load of 7, 13 and 25 N than high-chromium cast-iron. However, the intermetallic alloy exhibits better wear resistance under wear test load of 49 N. Abrasive wear of the laser melting deposition TiENi/TiNi alloy is governed by micro-cutting and plowing. Pseudoelasticity of TiNi plays an active role in contributing to abrasive wear resistance.
