Imagine the powder metallurgical process as a series of illustrated steps. The powders and additives mix, then they’re formed and sintered. The process is clearly marked out in the various illustrations. Adding another illustrated block to the process, infiltration action strengthens powder metal components. Basically, the technique adds a second metal to the part, and […]
There’s a tendency to put self-lubricating bearings in their own applications spotlight. Alternatively, given the chance, curious would-be engineers should try giving other powdered metal parts their chance to shine. Granted, bearing technology owes a lot to powder metallurgy, but there is a whole other range of equally capable powder-fabricated products, all of which use […]
Historically speaking, powdered metals are recognized as moderately strong materials. They form relatively hard bearings and other self-lubricating items. By heat treating sintered metal parts, they become even tougher. In point of fact, the sintering process uses thermal energy and pressure, so some heat treated hardenability is applied during the production phase. Okay, this strength-conversion […]
Shaft runout is described as a centreline deviation issue. To illustrate this drive transmission glitch, imagine the rod of a drive shaft. It moves around its axis, always. Should the drive rod’s centre of radial motion stray, it’ll develop runout. This drift movement is clearly undesirable. Nonetheless, runout problems and misalignment errors can occur in […]
Based on powder metallurgy technology, sintered bronze bearings deliver a very familiar feature. That opening sentence is, of course, referring to the material’s porous build. Friction counteracting lubricants are stored inside the metal’s tiny chambers. Okay, so this general property gets mentioned in every article, because that’s what the bearings do best, but there’s more […]
