Example Embodiment
[0034] Example 1
[0035] The invention provides a protective coating based on the working surface of a mold substrate. The preparation process of the coating is as follows figure 1 As shown, it includes the following steps:
[0036] 1) Cleaning of parts
[0037] Put the substrate to be processed in the acetone solution, and then put it into the ultrasonic cleaning test machine for ultrasonic cleaning, the cleaning time is 30 minutes; after the ultrasonic cleaning is completed, dry the substrate with a hair dryer and place it in the alcohol solution, and do it again Ultrasonic cleaning, the cleaning time is 30 minutes, and finally the substrate is blown dry with a hair dryer.
[0038] 2) Preparation of hard wear-resistant coating
[0039] Put the base material in the spraying workshop, fill the spray filler with an appropriate amount of SiC powder, and use low-temperature plasma spraying technology to spray (such as figure 2 As shown), a hard wear-resistant coating with a thickness of...
