AbstractThe diamond-like carbon (DLC) films added with silicon content from Oat% to 19.2at% were deposited using R.F. PECVD. By increasing the annealing temperature the groups of CHn and Si-H in FTIR spectra of the deposited films decrease because of hydrogen evolution, whereas the intensity of C=O and Si-O peaks increases due to oxidation. From Raman spectra, the observable shoulder of D band occurs at 400°C and 500°C respectively, which indicates that the addition of silicon improves the thermal stability of DLC films. A pin-on-disk wear test was conducted to investigate the wear behavior of the DLC films. DLC film with small amount of silicon addition has a lower friction coefficient (0.01) than the undoped one(0.1). Raman analysis showed that in wear test the graphitization of pure DLC film occurs at the initial stage whereas for the silicon containing DLC, graphitization of wear debris or transferred film was not observed after the wear test.

This study explored the effects of cryogenic treatment on the microstructure, hardness, and wear-resistance of diamond-like carbon (DLC) by cryogenically treating NAK 80 mold steel coated with DLC. Raman spectroscopy analyzed the structure of the DLC film. Nanoindenter analyzed the hardness and Young’s modulus of the film, and their relationship determined the wear resistance. Wear test assessed the wear rate and friction coefficient of the DLC film. The results showed that cryogenic treatment increased the rate of carbide precipitation and refined the grain structure. Raman spectroscopy indicated that the Raman intensity rate (ID/IG) of treated DLC films was smaller than those without cryogenic treatment. When the sp3 bond increased, the hardness and wear-resistance of the DLC film also increased.

ABSTRACTThin films of amorphous carbon/hydrogen, also known as diamond-like carbon or DLC, are of interest as an economical alternative to diamond in a variety of coatings applications. We have investigated the thermal stability of DLC films deposited onto tungsten and aluminum substrates via plasma CVD of methane. These films contain approximately 40 atom % hydrogen, and based on Auger spectra the carbon in the films is estimated to be approximately 60 % sp3 hybridized and 40 % sp2 hybridized. Thermal desorption, Auger, and Raman measurements all indicate that the DLC films are stable to 250–300° C. Between 300 and 500° C, thermal evolution of hydrogen from the films is accompanied by the conversion of carbon from sp3 to sp2 hybridization, and Raman spectra indicate the conversion of the overall film structure from DLC to micro-crystalline graphite or so-called “glassy” carbon. These results suggest that DLC of this type is potentially useful for applications in which the temperature does not exceed 250° C.
