In this paper, the author studied the effect of laser quenching scan time on the wear resistance of 45# steel against plant abrasive by using alfalfa meal as a typical plant abrasive. The results showed that under the experimental conditions, the maximum surface hardness of the material can reach 735HV, and the maximum hardness of the material is between 0.5 and 0.8 mm from the surface; the wear resistance of 45# steel after laser quenching is much higher than that without laser; the higher hardness of the treated specimen, the better wear resistance; in comparison with the untreated specimen, the plow depth of the surface of the specimen after laser treatment is significantly shallower and narrower, and the degree of fatigue wear is also significantly smaller than untreated specimen.
