Comparison Of Heat Treatment Technology And Vacuum Coating Technology
Jan 20, 2023| Comparison of heat treatment technology and vacuum coating technology
Two techniques improve the surface hardness of parts
As can be seen from the data in Table 4, the hardness of overall heat treatment quenching + low-temperature tempering is below Hv 800, and the highest Hv is 1200 after nitriding. The hardness of the hard coating is generally monolayer film >Hv 2000. In particular, DLC film can be deposited below 200℃. Therefore, the hard coating deposition technology is to add a new coat with a higher hardness to the tool, mold, and wear-resistant parts after heat treatment.
