Abstract:
From the perspective of the industry, the patented technology is the core of the industrial economy. Based on the research production technology of Ni-based superalloys, alloy products and enterprises in domestic and foreign, it uses some proper methods to choose the core patented technology of Ni-based superalloys. Based on the core patented technology of Ni-based superalloys, the article analyzes the main distribution areas, technical direction, owned enterprises of core technologies. It also draws the evolution map of core technology and products of Ni-based superalloy. The article focuses on the core technologies and these applications that including preparation technology, thermal barrier coating, heat-treatment, laser cladding and repair techniques. At last, it discusses the R & D direction of core technologies of Ni-based superalloys in recent years.
