  • Tribological reactions between oil additives and DLC coatings for automotive applications
    Podgornik, Bojan, 1970- ; Vižintin, Jože
    In the past, the development of modern engines and transmissions would have been impossible without advanced lubricant additive chemistry and proper lubricant formulation. Introduction of diamond and ... diamond-like carbon (DLC) coatings, especially metal doped DLC coatings, opens further possibilities in improving performance of engine and transmission components, which cannot longer be achieved only by lubricant design. However, the lack of knowledge ontribological behaviour of DLC coatings when lubricated with oils originally designed for metallic surfaces limit their use in practical applications. The results of the present investigation clearly show the existence of tribochemical reaction between metal doped DLC coatings (W-DLC) and S-based EPadditives, while for a-C:H coatings additives had no influence. Furthermore,tribological behaviour of W-DLC coatings was found to be EP additive concentration and contact temperature dependant.
