Because the TiN、TiAlN and TiCN coatings are popularly investigated before. Thereby, in this case, use TiAlSi target and Cr target moreover N2 gas was through into with the process parameters to deposited AlTiSiN and AlTiCrN/CrN two mixed films, and then study the structure of the coatings by XRD, the morphology by SEM, on the characteristics, we measure the adhesions, the hardness, and the corrosion behaviors. They expect to obtain excellent properties besides to compare with Nitrided DC53 steel.
Via knew with the experiment, Nitriding improves surface hardness, there are big drop in roughness (Ra)、adhesion and porosity, moreover the structure remain still. Also because the bad adhesion decrease to took effect with the corrosion resistance.
