The invention discloses aero-engine aluminizing slurry for photocuring and a preparation method and application. The aero-engine aluminizing slurry for photocuring comprises aluminum oxide powder, chromium powder, aluminum-silicon alloy powder, boron carbide powder and ammonium chloride powder in a mass ratio of (18-54) to (1-3) to (48-54) to (0.5-3) to (0.2-0.4). According to an aluminizing method of the aero-engine aluminizing slurry for photocuring, the aluminum oxide powder and the boron carbide powder are added, the aluminum oxide powder can ensure that one layer of uniform aluminum oxide is formed on an aero-engine aluminizing part, therefore the corrosion resistance can be improved, and the boron carbide powder can improve the wear resistance of the aluminizing part; and according to the aero-engine aluminizing slurry for photocuring and the preparation method and the application, the part is formed through photocuring, firstly, photocuring forming does not need mold assistance, the forming precision i
