Abstract
Disclosed is a method for a compound strengthening treatment of a gear surface, belonging to the technical field of gear surface treatment, including following steps: firstly, performing a compound shot peening treatment on the gear surface, and then performing molybdenum disulfide micro-particle thermal spraying on the obtained gear surface to complete the compound strengthening treatment on the gear surface.
Claims8
A method for a compound strengthening treatment of a gear surface, comprising:
- firstly, performing a compound shot peening treatment on the gear surface with a diameter of 0.2-0.25 mm, and then performing molybdenum disulfide micro-particle thermal spraying on the shot peened surface to complete the compound strengthening treatment on the gear surface with a diameter of 0.1-0.15 mm, wherein a shot peening angle of the two shot peenings is 80-100°, a shot flow rate is 4-6 kilograms (kg)/minute, and a spraying distance is 150-170 mm;
- and a shot peening coverage is 180-220%.
