Experimental Research of Dry Friction in "Alumina Ceramics - Quartz Glass" Pair

Results of an experimental research of friction coefficient in "alumina ceramics - quartz glass" friction pair are presented. The research with pin on disc test configuration using SRV-III test machine was carried out at loads from 10 to 1000 N, constant sliding velocities 5 mm/s; ambient temperature 23°C and relative humidity 30%. The obtained results reveal that in general, friction coefficient for "alumina ceramics - quartz glass" pair decreases with the increase in normal load. It is shown that the obtained friction coefficients values at the normal force from 100 to 1000 N for the given experimental conditions can be used to pre-estimate the interference fits in "alumina ceramics - quartz glass" friction pairs.
