Analysis of Wear Behaviour of Sintering Carbide against DLC Coated and Nitriding Steel
In this paper, tribological behaviours for sintering carbides and DLC/nitride film are discussed. During the wear test, two types of hardened steel are setting to sliding against eight series of carbide specimens in order to compare the wear mode and evaluate the wear performance of sintering carbides, which are made by different process parameters. The experiment result shows that a density ratio of sintering carbide between 86% and 99% does not have obviously different effect on wear resistance. Moreover, molybdenum binder with high diffusibility can improve the wear performance of tungsten carbide, but wear performance of titanium carbide is dependent on the amount of nickel/cobalt binder, separately. On the other hand, SAE52100 substrate absorbs the heat of friction and maintains the coated diamond-like carbon film in an excellent wear performance.
