One-way single press and single sintering is improving with selectively densifying areas of critical importance and leaving the core—or non-critical areas—at a lower density. By using powder metallurgy, parts can be produced with infiltration and impregnation of other materials to obtain special characteristics which are needed for specific application.
Powder Metallurgy What is Powder Metallurgy? Powders can be tailor-made to meet the most important property requirements. Generally, PM is competitive with casting, machining, and forging, and often associated with the aerospace, power, and medical industries.
Powders might not be able to handle as much force as some of the AHSS, but the process allows for porosity and complex shapes that can reduce cost, material, and weight.
It is a versatile, cost-effective, and constantly expanding technology that is rapidly gaining worldwide popularity. Bycemented carbides and impregnated lubricants in ball bearings started changing the machine industry.
