Powder Metallurgy Part 2 (1945)

The film discusses the process of powder metallurgy, which involves creating metal parts from metal powders. It explains how metal powders are mixed, compacted under pressure, and subjected to heat to form unique metallic materials. A notable application is the production of porous self-lubricating bearings, which carry their own oil supply due to their special structure. The process includes careful measurement and blending of metal powders, pressing them into briquettes, heat treatment to bond the particles, and sizing for precision. Finally, the bearings are impregnated with oil, allowing them to maintain proper lubrication during operation, showcasing the efficiency and innovation of powder metallurgy in modern technology.
