The Influence of the Applied Load on the Friction Coefficient of the Sintered Iron-Base Bearings

Teișanu, Cristina; Gheorghe, Ștefan; Tudor, Andrei; Ciupitu, Ion (Universitatea ”Dunărea de Jos” din Galați, 2008)

In the recent years the iron base sintered bearings production was considerable increased at the expense of the copper based ones, due to the low cost and availability of the iron powders as well as the higher strength. ...
The Influence of the Sintering Atmospheres on the Wear Behaviour of the Copper Based Alloys

Gheorghe, Ștefan; Teișanu, Cristina; Merstallinger, Andreas; Ciupitu, Ion (UDJG, 2010)

The Powder Metallurgy (PM) technique allows manufacturing the sintered selflubricating materials having a high wear resistance. It is well known that the small and medium sized bearings are processed by PM with better ...
