Abstract. A method for fast evaluation of tribological parameters of wear-resistant materials is proposed. Estimation of wear is based on comparison of analyzed material surface profiles before and after friction testing. Evaluation of the friction coefficient is performed in normal braking conditions.
Keywords: coefficient of friction, wear, surface profile, single crystal sapphire, silicon nitride ceramics
