Abstract

One of the fundamental means to improve the mechanical strength of sintered components is to increase the density. In order to meet the performance of high strength application, such as transmission gears, high density is of outmost importance. In this paper recent development of mixes with high performance PM lubricants will be presented. By improving the efficiency of the lubricant lower amount is required in the mix and thus higher density can be achieved. The potential increase of compacted density will be demonstrated. A case study where a helical transmission gear was compacted to high density is presented.
