Powder metallurgy (PM) is a manufacturing process in which metal powders, or mixtures of metal and non-metal powders, are compacted into desired shapes within a die cavity and then sintered and finished to produce powdered-metal mechanical components. It is a material- and energy-saving, low-investment, fast-acting, pollution-free, high-efficiency metal-forming process that is well suited for mass production. PM has been widely adopted in industries such as automotive, motorcycle, and agricultural machinery manufacturing, with particular emphasis in the automotive sector. In recent years, the use of PM processes to manufacture components for automotive powertrains has continued to grow, driven by the significant and unique advantages of PM-produced parts: reduced costs, enhanced performance, lighter weight, and environmental benefits. Powder metallurgy technology can produce materials and components with specific properties that cannot be achieved through conventional melting methods; moreover, the inherent porosity of PM parts confers self-lubricating and sound-insulating characteristics. Although one of the original goals of the PM industry was to eliminate all machining operations, this objective has yet to be fully realized—most PM parts are produced in a “near-net-shape” condition and still require finishing to meet specified dimensional tolerances and surface roughness requirements. However, because the microstructure of PM materials differs from that of castings and forgings, their machinability also exhibits distinctive features.
