As far as we know, powder metallurgy is an advanced modern metal spare parts forming technology,it is a high and new technology of mechanical spare parts and metal products by compacting,sintering and secondary process.As the advantages of energe saving,material saving,high efficient and environmental protection,it has been applied on various industries widely and possessed huge market potential and development prospect.In recent years,powder metallurgy technology has been innovated rapidly,especially automobile manufacturing industry,machines manufacturing industry,aerospace industry,instrument industry,hardware tools industry,mechanical engineering industry,electronic home-appliance and high technology industry,so a rare opportunity and huge market has been brought for powder metallurgy,at the same time,more stricter requirement is pointed out for powder metallurgy industry.
As the rapid progress of global economy integration,powder metallurgy industry in domestic China is facing new challenges,at the same time,the competition on powder metallurgy industry between different countries all over the world become more and more sharp.So based on this sharp circumstance,the powder metallurgy industry in our country must been innovated rapidly,otherwise,we would lose the power.
The development directions of powder metallurgy material and products mainly are: the representative iron base alloy material would be adopted to produce high precison and quality spare parts with big volume and be used to produce high performance alloy with uniform micro orgnization structure and process difficulities.
