摘　　要：将Ni基粉末与一定比例的Al粉机械混合并喷涂于基材上,在700℃进行反应烧结,形成高强度致密涂层。实验表明,涂层所固有的层状组织趋于消失,强度明显提高。该涂层在过程装备中具有广阔的应用前景。The Ni-base powder mixed with Al powder of a certain proportion was sprayed on the surface,then the coating was reaction-sintered in the furnace at about 700℃ for getting a high-strength compact coating.The results show that the layer shape structure of thermal sprayed coating has been almost disappeared and the bonding strength has been improved clearly.There will be a great application in the processing equipment.
