Therefore, ultrafine metal powder materials can be widely used in aerospace, ship, automobile, metallurgy, chemical industry and other fields. ultrafine metal powder can be prepared by mechanical method and physical method. today, the author will share with you the preparation method of ultrafine metal powder airflow grinding method.

What is high temperature powder metal high temperature pm or the powder metal sintering process focuses on providing a costeffective alternative to forging, stamping, casting, and machining processes. it combines the high volume process of pm compaction with superior physical properties achieved through an increased temperaturecontrolled atmosphere called quotsinteringquot.

The basic process is to mix up the epoxy and then slowly add more and more metal powder, mixing with each addition until you have a thick paste. at this point you can literally smear and press it into the gaps you want to fill, and if they are vertical then duct tape over the top to stop the mix from slumping out note that if you do this, you ...
