The equipment of liquid electro-deposition for diamond-like carbon (DLC) films was set up. DLC films were deposited on stainless steel and Si substrates by electrolysis in a methanol solution with a pulse-direct current power supply. The morphology and microstructure of the deposited DLC films were analyzed using scanning electron microscopy (SEM) and Raman spectroscopy. Friction and wear properties of the films were tested by the UMT-2M friction-wear tester of CETR Corporation. The experimental results show that DLC films are smooth and compact. Raman spectroscopy analysis confirmed the presence of a strong peak at 1332 cm-1, which is assigned to crystalline diamond. The content of sp3 for the stainless steel substrate is higher than that for the Si substrates. At ambient conditions, the friction coefficient of DLC films on stainless steel substrates is 0.12, and the friction coefficient of DLC films on Si substrates is 0.10. The wear-resistant property of DLC films on stainless steel substrates is more excellent than that of DLC films on Si substrates.
