Calculation of wear rate Tribology

网页2013年2月27日  A common used equation to compute the wear rate is (Archard,1953). V =k F s. where F is the normal load, s the sliding distance, V the wear volume and k the specific wear rate coefficient. Index i identifies the surface considered. The k-value is given in m 3 /Nm or m 2 /N, sometimes in mm 3 /Nm.
