Powder metallurgy plays a very big role in the production of
contemporary new material as a new technique, but we do not know the basic
properties of powder metallurgy is determined by which aspect. Finally, post
treatments for powder metallurgy are complex pressure, impregnation, heat
treatment , surface treatment and cutting processing.
In powder metallurgy production process, follow-up process is for
improving performance of products, including finishing and shaping. Finishing
carried out to achieve complex Pressure meet the dimensions of parts, usually
by applying pressure on the sintered body to improve accuracy of powder
metallurgy products. Shaping is to make powder metallurgy products meet
specific surface shape, and a one-time forming. By machining to reduce the
surface roughness of products, improving the main properties of powder
metallurgy products. For conventional powder metallurgy products processing,
the final step is so important and
reasonable production is directly related to product performance and life.
The final process is vital for powder metallurgy technology. Taking
metal powder as raw material, powder metallurgy products use abrasive tool for
processing to make parts with a high finishing to improve powder metallurgy
product performance。
