• In this study, the deposition of diamond-like carbon (DLC) films for fabricating a wear-resistant and anti-corrosive barrel bore using a microwave plasma chemical vapor deposition system was investigated. Coatings were deposited on a nitrified steel substrate at a pressure of 5 kPa and temperatures of 450–650 °C. Before depositing the DLC films, a Si+Ag interlayer was employed to enhance adhesion. The mechanical properties of the DLC films were evaluated by nano-hardness and explosion tests, while the physical properties were evaluated by Raman spectral analysis. The result of the nano-hardness test showed that the adhesion of the DLC films was superior to that of the HF1 grade, and the explosion test showed that the DLC films were able to withstand this pressure without peeling off. Also, according to the characteristics of the films determined by Raman spectral analysis, the intensity ratio of the D-band to the G-band $I$(D)/$I$(G), increased after the explosion test while the positions of the D-band and G-band shifted upward, which indicates that the sp3 structure gradually changed into an sp2 structure. This research shows that, in a explosion test, DLC films can withstand intense but very brief temperatures.
