Embodiment 1
[0026] A repair process for automobile molds with excellent repair effect, the steps are as follows:
[0027] 1) Cleaning the surface of the mold, specifically, cleaning the mold with methacron solvent at 70°C;
[0028] 2) Use the worn area of the mold as the repair area, and polish the repair area. Specifically, firstly use 400-mesh dry sandpaper to polish the mold for the first time, and after grinding evenly, use 800-mesh dry sandpaper to polish the mold again to make the mold evenly Finally, put the mold in water, and use 1200-mesh water-grinding sandpaper for final grinding. After grinding evenly, dry the mold at 110°C;
[0029] 3) Perform initial tempering treatment on the mold, first raise the temperature to 500°C, temper for 2 hours, then cool down to 210°C, temper for 1 hour, and finally cool naturally;
[0030] 4) Laser cladding is used to clad the repaired alloy powder on the repaired area to form a repaired layer, and the surface of the repaired layer is 0.3mm l...
