We have tried to produce TiAl and TiNi powder and TiAl and TiNi coating on substrate from composite wire of titanium and aluminium. The composite wire was melted by using COィイD22ィエD2 laser in an atmosphere of nitrogen or argon gas and melted metal was atomized and coated on the SUS304 steel or aluminium by high pressure nitrogen or argon gas at atmosphere and in chamber. Effect of spray condition on size of powder and porosity of coating layer. Wear resistance of the coating layer was evaluted by using an Ohgoshi and Arata wear tester.It was possible to produce TiAl and TiNi intermetallic compound powder and coating layer using a composite wire by a laser reactive spray method. The size of powders was in the range from 10μm to 200μm.The coating layer of TiAl was consisted of a large amount of TiAl intermetallic conpuond and a small amount of TiィイD23ィエD2Al. The coating layer TiNi was consist of 100% TiNi. As the spray dintance incerased and the atomize gas pressure decreased, the porosity of coating layer decrased. The wear resistance of TiAl and TiNi coating layer increased by about ten times that of aluminium. The wear resistance of TiNi coating layer by produced in chamber about twenty times that of aluminium.

我们尝试以钛铝复合丝为原料，在氮气或氩气气氛下，采用CO22激光熔化复合丝，将熔化的金属雾化涂覆在基体上制备TiAl、TiNi粉末及TiAl、TiNi涂层。 SUS304钢或铝在大气和室内用高压氮气或氩气喷涂条件对粉末尺寸和涂层孔隙率的影响。采用Ohgoshi和Arata磨损试验机对涂层的耐磨性进行了评价。采用激光反应喷涂法制备了TiAl和TiNi金属间化合物粉末和涂层。范围从10μm到200μm。TiAl涂层由大量的TiAl金属间化合物和少量的TiAl金属间化合物组成。 TiD23D2Al涂层由100%TiNi组成，随着喷涂距离的增加和雾化气压的降低，涂层的孔隙率降低，TiAl和TiNi涂层的耐磨性提高了约10倍。在腔室中生成的TiNi涂层的耐磨性约为铝的二十倍。
