Wear Resistance of Nano Alumina Containing SiO2-B2O3-Na2O Glass-Ceramic on Steel Substrate
Journal Title: Tribology in Industry - Year 2016, Vol 38, Issue 3
Abstract
The experimental study has been carried out to investigate the tribological properties of nano Alumina reinforced glass-ceramic enamel. The mixtures of (5, 10, 15 wt.%) nano alumina and glass powders have been air sprayed on stainless steel substrate.. The thixotropy, wetting angle and surface tension of used slurry were increased inherently by 15-wt.% nano alumina. By heat treating at 870-640-525 ºC, the homogeneous crystalline sodium silicate phase beside nano alumina was obtained in glass –ceramic coat. According to the EDAX results, the precipitated reduced Sb and Mo particles at the interface of enamel and steel caused to reasonable adherence of coat and steel. The dry sliding wear tests were carried out using pin on disk method. Results revealed the 0.01 mg wear rate by 30N load at 100 m for nano alumina bearing coats. The wear resistance increased by a factor of 10. According to SEM micrographs, the sliding load transfer by nano alumina particles occurred.
