As the rapid development of global industries,powder metallurgy technology has been applied to vehical industry, mechanical industry,electronic industry and aerospace industry and so on,especially automobile manufacturing industry.The rapid development circumstance of automobile manufacturing industry has promoted the application of powder metallurgy technology on automotive spare parts greatly,so automobile industry has become one of the largest application fields of powder metallurgy spare parts.
As far as we know,metal powder or the mixture of metal powder and non metal powder are the raw material of powder metallurgy produce process,by compacting ans sintering,various complex and precise metal parts or composite material parts and other spare parts could be finished.Powder metallurgy manufacturing is very similar to the manufacturing method of ceramic material parts,both of them are the powder sintering technology.Thus a serious of powder metallurgy technology could be used on the preparation of ceramic material.With the advantages of powder metallurgy technology,powder metallurgy has become one of the key to solve the new material problems and always play an important role on the development progress of new material.
Powder metallurgy including the preparation of metal and non metal powder and the production of metal parts.For the preparation of metal and non metal powder,it is the metallurgy processing mainly,while powder metallurgy parts has exceeded the scope of material and metallurgy,so it is always the acrossing multiple subjects(material,powder metallurgy,machinery and mechanics) technology,especially modern metal powder 3D printing technology,inculding the mechanical engineering,CAD,CNC machining,material science and laser technology,so it is no doubt that modern powder technology has become one comprehensive technology.
