Summary: | The invention discloses an aluminum alloy electron beam vacuum evaporation composite surface strengthening method which specifically comprises the following steps: step 1, pretreatment: milling and polishing the surface of an aluminum alloy test block workpiece, and then cleaning the processed workpiece and an evaporation target material by using a cleaning agent; and 2, electron beam vacuum evaporation treatment is carried out, and the evaporation target material is heated through an electron beam to be evaporated. And (3) electron beam treatment: continuously treating the surface of the aluminum alloy coating by using an electron beam. And 4, structure and performance testing: observing the internal structure by using a scanning electron microscope, detecting the corrosion resistance of the structure by using an electrochemical workstation, and measuring the hardness by using a microhardness meter. The method disclosed by the invention not only can improve the corrosion resistance of the aluminum alloy surf |
