Porous slide sleeves sintered from iron powder with addition of hexagonal boron nitride
Journal Title: Bulletin of the Military University of Technology - Year 2014, Vol 63, Issue 1
Abstract
In this article there are presented some selected results of research works on new generationporous slide bearings, sintered from Höganas NC .100.24 iron powder, with addition of hexagonalboron nitride h-BN instead of copper or graphite powder. The research was carried out withinthe framework of PBR/15-249/2007/WA T-OR 00002904 Research Project financed by the Ministry ofScience and Higher Education, during 2007-2011 [1]. Significant increase in capacity and durability ofØ25/Ø35 × 20 mm porous sleeves containing 3% of boron nitride h-BN by weight in the iron sinterwas obtained in comparison to the same standard sleeves containing 2.5% of copper. To date there areno bearings sintered from iron powder with addition of h-BN. Owing to this fact, their durability andload capacity are higher, and that is why it was decided to submit a proper patent claim to the PolishPatent Office [2][b]Keywords[/b]: porous sleeves, iron sinter, boron nitride
