Embodiment Construction
[0027] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited to the examples.
[0028] This embodiment adopts a small-pitch standard gear made of 304 stainless steel used at the engine end of an automobile, and its geometric dimensions are as follows: the number of teeth is 50, the modulus is 1 mm, and the pitch is 3 mm.
[0029] An example of using the above-mentioned workpiece for laser shock strengthening, the specific steps are:
[0030] (1) Mix PVC organic sol, acrylic synthetic resin and organic solvent thickener aluminum hydroxide in a certain proportion, and stir fully to form a uniform viscous transparent filling, and the components of the transparent filling The ratio by weight is: 70g of PVC organosol, 28g of acrylic synthetic resin, and 2g of organic solvent thickener.
[0031] (2) Put the above-mentioned transparent filler into a vacuum to discharge the air bub...
