POWDER METALLURGY
POWDER METALLURGY Definition:- What does Powder Metallurgy (PM) mean? Powder metallurgy (PM) is a process for forming metal parts by heating compacted metal powders to just below their melting points. In other words PM is metal shaping process that creates near-net parts from powdered metal. Powder metallurgy is the process of blending fine powdered materials pressing them into desired shape or form (compacting), and then heating the compressed material in a controlled atmosphere to bond the material (sintering). The powder metallurgy process consists of four basic steps. Powder manufacture Powder blending Compacting Sintering Advantages The PM process provides a host of advantages over competing metalworking technologies moluding. Cost effectiveness Shape and material versatility Application versatility Part-to-part uniformity Virtually unlimited choice of alloys and non metallics with associated properties A variety of metal or non metal powders can be used.
