Notes:
The contact in the valve train system is known to be the part subject to significant load in anautomobile engine. For such reason, the wear of the contact accounts for the greatest portion of entirefriction loss of an engine, leading to the occurrence of abnormal wear. In order to reduce the wear inthe valve train, this study first formed a crn layer to increase the bonding force with the base metalusing the pvd coating method and then applied a 2-layer coating that formed the wc/c layer with lowfriction/wear resistance characteristics. In addition, it examined the friction characteristics occurringbetween the cam and tappet by using the dedicated wear tester and found that the friction torque valuewas reduced significantly through comparison testing with the existing part when the crn+wc/ccoating was applied
