The two new techniques in the surface engineering area, combustion synthesis coating and laser surface cladding were combined in this research. The goal was to develop a novel surface treatment technique---laser controlled reactive synthesis cladding, to integrate the advantages of the above two techniques, Al and Fe2O3 powders for the highly exothermic reaction:2Al + Fe2O3 = Fe+ Al2O3 was used as the basic reacting reactants. SHS process was prevented. The laser cladding processes were experimented by laser static illuminating on pressed samples and single track cladding on the steel substrate, respectively. The optimum ratio of powder mixture and suitable processing parameters were obtained.

本文把表面工程领域两种先进技术——燃烧合成涂层技术和激光表面熔覆技术结合起来进行研究,旨在使这两种表面处理技术优势互补,获得一种新的表面处理技术——激光控制反应合成表面熔覆技术。在结合实验的基础上,研究了在铝热自蔓延反应2Al+Fe_2O_3=2Fe+Al_2O_3的反应物中添加合适的稀释剂,使此体系无法自蔓延,再通过激光能量的输入来诱发和控制反应合成,从而实现在钢板表面的激光陶瓷熔覆。

Effects of compact density and laser power density on the macrostructure and microstructure of the Ni3Al intermetallics were investigated by the laser controlled reactive synthesis and cladding process. Microstructure and contents were researched by SEM and XRD. It is shown that in appreciated range of compact density about 60% and laser power 1 000—1 200 W and 1 mm/s scanning velocity, a continuous, fully dense and uniform Ni3Al intermetallics coating can be obtained.

研究了粉末压坯紧实率、功率密度等参数对激光控制反应合成Ni3Al金属间化合物熔敷层的宏观、微观形貌的影响,采用扫描电镜和X射线衍射仪分析了合成产物的微观组织和成分.结果表明,在压坯紧实率60%、激光功率1000~1200W、扫描速度1mm/s的工艺条件下,能够得到连续、致密具有较高纯度的Ni3Al金属间化合物熔敷层.
