THE POSSIBILITY OF THE APPLICATION OF BORON NITRIDE h-BN AS A COMPONENT OF IRON POROUS SINTER
Journal Title: Tribologia - Year 2013, Vol 249, Issue 3
Abstract
The results of research on the iron sinters containing various amounts hexagonal boron nitride h-BN are presented in this paper. The tribological research was realised with KEWAT-6 and KEWAT-1 machines at the Department of Tribology, Surface Engineering and Service Fluids Logistics of the Institute of Motor Vehicles and Transportation, FME, MUT. The paper concludes that boron nitride up to 3% by weight in the iron sinter of Höganas NC.100.24 iron powder efficiently increases tribological properties of the sinter, i.e. it lowers the value of the friction factor without increasing the wear of sintered samples. However, their hardness was slightly decreased. These results were the basis for making some full-size porous sleeves, which included boron nitride h-BN in the sinter. The sleeves were then subjected to stand tests within the framework of the development and research project number PBR/15-249/2007/WATOR00002904 [L. 1], financed by the Ministry of Science and Higher Education, 2007–2011. Very advantageous results were obtained from these tests, which allowed us to make a patent claim [L. 8].
