Abstract
The purpose of this investigation is to analyze the friction and wear prope rties of CVD-SiC films finished with ELID-grinding and conventional grindin g under dry condition. Normal load is changed from 0.049N to 9.8 N, the fol lowing results are obtained: the friction coefficient of CVD-SiC films fini shed with two kinds of grinding method show similar results; specific wear rate of CVD-SiC films with ELID-grinding does not depend on the grinding di rection; wear mode are classified into two types, powder formation (w great er than or equal to 10(-9)mm(2)/N) and without powder formation (ws less th an or equal to 3x10(-10)mm(2)/N).;CVD-SiC films with ELID-grinding showed h igh wear resistance because the wear mode of powder formation did not occur when P-max is less than P-max.c.; transition between powder formation and non powder formation is explained in terms of the dimensionless parameter S -c* and transition of specific wear rate is explained in terms of the dimen sionless parameter S-w*.
