Low Friction Tribobond™ DLC on valve train components
The tappet or finger follower interface to the camshaft is where the material is exposed to the highest loads and where a lot of energy is lost due to friction.
The properties of Tribobond™ DLC coatings ease the wear effect of cold starts before oil pressure is built up.
The coating can be applied to various types of cam followers and on camshafts. If the highest reduction of friction is desired or if there is a risk of loss of lubrication, both mating surfaces are coated.
