Hardening Methods of Powder Metallurgy Parts
On occasion, when sintered components need to exhibit a predetermined quantity of mechanical toughness, the parts are subjected to special supplementary operations. The finishing service, which is typically carried out in-house, further hardens a sintered component’s internal structure. Now, heat treatment principles obviously dominate this post-production phase, but there are other secondary hardening methods of […]
Do Sintered Bearings Need Heat Treatment?
Powder metallurgy represents something of an ideal production model. There are no costly castings to produce, and the bearings possess a highly desirable self-lubricating feature. It’s also possible to make sintered bearings without incorporating a post-production stage, although this part of the operation is often recommended. With that said, apart from the end-phase jobs that […]
