Abstract
TiC coatings on 440C stainless steel (SS) substrates that contain different kinds of interlayers (Ti, Cr and Mo) of different thickness were grown by magnetron sputtering. The friction, wear and adhesion behaviors were investigated for the TiC coatings using pin-on-disk configuration. The wear tracks of the TiC coatings and alumina pin were characterized by optical microscope or scanning electron microscope (SEM). Inserting Cr or Ti interlayer between TiC coating and substrate could improve greatly the wear, hardness and adhesion. In wear tests the TiC coating with Cr interlayer usually showed better characteristics than that with Ti interlayer. In addition, the TiC coating with 50 nm Ti interlayer performed better than that with 500 nm Ti interlayer in the adhesion and wear tests. It is noticed that the TiC coating could not be improved on the friction and wear behavior when metallic Mo was inserted between the TiC and substrate resulting from the poor adhesion of the coating.
