材料制备与成形一体化技术是装备再制造关键技术之一。对于一些难以合成及加工成形的材料,采用高速电弧喷涂粉芯丝材的方法,通过喷涂弧区的快速、动态冶金过程,同步实现新材料的合成与成形,即在再制造快速成形过程中实现新材料的合成与制备。这一技术一方面可通过新材料设计,制备出赋予零件防腐蚀、耐磨损、耐高温等性能的涂层体系,另一方面它突破了热喷涂技术只能制备薄涂层传统观念,在开展制造零件用的快速成形材料方面也具有良好的研究空间。基于高速电弧喷涂的材料制备与成形一体化技术在舰船钢结构长效防腐、电站锅炉管道防护、装备零件成形制造与再制造等领域具有良好的应用前景。
Material preparation and forming integration technology is one of the key technologies in equipment remanufacturing. For some difficult to synthesize and processing of materials, using high-speed arc spraying cored wire method, through the spraying arc zone rapid and dynamic metallurgical process, the synchronization of new materials synthesis and forming, that is, in the rapid prototyping remanufacturing process Synthesis and preparation of new materials. This technology, on the one hand, can be designed through new materials to prepare a coating system that gives parts corrosion resistance, wear resistance and high temperature resistance. On the other hand, it breaks through the traditional concept that thermal spraying technology can only prepare thin coatings. There is also a good research space for carrying out rapid prototyping of parts for manufacturing parts. The technology of material preparation and forming based on high-speed arc spraying has good application prospects in the fields of long-term corrosion protection of ship steel structure, pipeline protection of power station boiler, forming and remanufacturing of spare parts of equipment.
