| Summary |
|---|
| The course is focused on the technology of Powder metallurgy (PM), its advantages, limits and applications. PM is used to produce unique structural components and functional materials that are not possible or difficult to produce by conventional methods. Around 70 % of the structural parts produced by PM are consumed by the automotive industry. PM is also used in the production of a wide variety of materials for the electrical engineering (contact materials, refractory materials, magnetic materials, etc.) and machining industry (cemented carbides, cermets, CBN, diamodic tools, etc.). PM is an established green manufacturing technology for the production of net-shape components, which involves several steps: powder production, blending and mixing, compaction, and sintering. The input material for the powder production contains better than 85 % scrap metal and material utilization rates is on average better than 97 %. |
