Some Intermetallic compounds have superior characteristics like shape memory effect, inverted temperature dependence of strength and corrosion resistance. This work has tried to produce TiNi, NiAl and TiAl coatings on Al and stainless steel substrates, which have wear resistance, and also, has curried out to control the compositions of intermetallic compound coatings for tailored materials by using the new innovative processing of laser spraying which use the composite stranded wire of Ni-Al, Fe-Al and Fe-Al-Ti wires, respectively. The shape and size of sprayed particles can be controlled by the conditions of laser spraying pressures and laser powers. Those coatings were consisted of tailored compositions of Ni3Al, FeAl and TiAl intermetallic compound. The developed new laser spraying process can be control the compositions of spraying coatings as tailored coatings for intermetallic compounds. A combination ratio was determined at the producing step of stranded wire. The target composition of intermetallic compounds coatings was calculated from the equations for tailored composition of coating materials. The combination ratio of stranded wire will be estimated by the calculated target composition. The processing of laser spraying can be applied for producing ecologically tailored coatings for some production machines, especially for steel parts of machines such as rolls, gear wheels and friction and rotating parts. Innovative processing of laser splaying method can be produced a tailored coating for intermetallic compounds as surface modification.

一些金属间化合物具有形状记忆效应、强度温度依赖性和耐腐蚀性等优良特性。本工作试图在铝和不锈钢表面制备耐磨的TiNi、NiAl和TiAl涂层，并采用激光喷涂新工艺控制金属间化合物涂层的成分。激光喷涂新工艺分别采用Ni-Al、Fe-Al和Fe-Al-Ti丝复合绞线。激光喷涂压力和激光功率可以控制喷涂颗粒的形状和大小。涂层由Ni3Al、FeAl和TiAl金属间化合物组成。开发的激光喷涂新工艺可以控制喷涂涂层的成分，作为金属间化合物的定制涂层。在钢绞线生产过程中，确定了不同的组合比例。根据涂层材料的剪裁成分方程，计算了金属间化合物涂层的目标成分。根据计算出的靶材成分，估算出多股绞线的结合率。激光喷涂工艺可应用于某些生产机械，特别是轧辊、齿轮、摩擦旋转等机械钢件的生态化涂层生产。创新的激光抛光加工方法可以为金属间化合物量身定做一层涂层作为表面改性。
