Characteristics of Low Density Powder Metallurgy Parts

When powder metallurgy tech produces low-density parts, the components are leaving the process as lightweight and porous constructs. Structurally attenuated, the parts consume less alloy powder, so process costs drop. Beyond such utilitarian deliberations, however, the lighter than usual parts gain self-lubricating improvements, so a lower frictional coefficient is instantly gained. Expanding on those observations, […]

Effects of Heat Treatment on Sintered Metals

A tightly narrated overview pinned down the main operational components in the powder metallurgical process. At this point, a new opportunity has arisen. It’s a chance to look beyond the manufacturing technique, to view the effects of heat treatment on sintered metals. Do sintered objects bend to the will of a furnace or tempering station? […]

Compaction of Metal Powders: What is it All About?

It’s been a short but eventful journey so far. The powder has progressed from its initial ingress point. Atomized and mixed, the blending chamber tumbled and spun while exotic chemical additives and lubricating agents were decanted. Next in the processing chain, the compaction phase is applied. The consolidated mass arrives as a shapeless lump, and […]

Oil Impregnation Process in Sintered Bearings

In sintering factories, self-lubricating bearings are manufactured by powder metallurgy (PM) equipment. The machines use a mixing process, not solid component mouldings. Thanks to that difference, manufacturing engineers gain mastery over the subject metal. That’s a powerful manufacturing advantage, one that introduces a lubricating medium to sintered bearings. Technically speaking, we’re in oil impregnation territory, […]

Top Features and Qualities of Sintered Bronze Bearings

Sintered bronze bearings perform an essential role in many applications. The friction dissolving components self-lubricate, they require little maintenance, and they’re economically priced. Now, we’ve already described the lubricant impregnation process in some detail. Furthermore, we’ve talked about powder metallurgy, the science that makes this partnership possible. Proceeding further on this track, we’re about to […]
