采用激光熔融沉积工艺制备了由TiNi一次枝晶和Ti 2Ni基体组成的耐磨金属间化合物合金。在室温下，在98 N、147 N和196 N载荷下，采用轮块式干滑动磨损试验机对Ti 2Ni/TiNi合金的耐磨性进行了评价。结果表明，Ti 2Ni/TiNi金属间化合物合金具有良好的强韧性配合，具有较高的耐磨性。在干滑动磨损过程中，Ti 2Ni/TiNi金属间化合物合金磨损表面形成了覆盖层。转移层通过防止Ti 2 Ni/TiNi合金表面与配合轮直接接触，在减少磨损质量损失方面发挥了积极作用。(C)2007爱思唯尔有限公司保留所有权利。
A wear resistant intermetallic alloy consisting of TiNi primary dendrite and Ti2Ni matrix was fabricated by the laser melting deposition manufacturing process. Wear resistance of the Ti2Ni/TiNi alloy was evaluated on a block-on-wheel dry sliding wear tester at room temperature under the loads of 98 N, 147 N and 196 N. Results indicate that the Ti2Ni/TiNi inter-metallic alloy exhibited high wear resistance due to its good combination of strength and toughness. Cover-layers were formed on the worn surface of the Ti2Ni/TiNi intermetallic alloy during the dry sliding wear. Transferred layers played an active role in reducing wear mass loss by preventing the surface of Ti2Ni/TiNi alloy from direct contact with the mating wheel. (C) 2007 Elsevier Ltd. All rights reserved.
