Embodiment 1
[0050] A wet shot peening surface modification treatment method suitable for nickel-based superalloys, comprising:
[0051] Step 1: Determine the shot peening parameters such as the target shot peening intensity and target coverage according to the size specifications and performance requirements of the parts;
[0052] Step 2: Clean the surface of the sample or parts to ensure that there is no oil or other pollutants on the surface of the sample;
[0053] Step 3: Check the sample or parts, wrap and block the parts with tape or rubber skin, protect the parts that cannot be shot blasted, and ensure that the processes before shot blasting are in place;
[0054] Step 4: Clamp the parts and protect the parts that do not need shot blasting;
[0055] Step 5: Use JY-120WB liquid shot blasting machine to carry out wet shot peening treatment. The strength of the ceramic shot used is 0.3mmC. The specification is selected with reference to HBZ 26-2011. The mass ratio of water to ceramic ...
