Preparation of Superhydrophobic Protective Film on Aluminum Alloy by Electrodeposition Assisted Vacuum Treatment and Its Performance Research
Aluminum alloy is a commonly used metal material in the industrial field.In order to make it a high-performance superhydrophobic material that is resistant to pollution and corrosion,aluminum alloy was used as the substrate,lanthanum nitrate was used as the electrodeposition solution,electrodeposition assisted vacuum treatment method was used to directly prepare the surface of superhydrophobic aluminum alloy without modification.By characterizing and testing the morphology,chemical composition,wettability,self-cleaning,and corrosion resistance of the prepared superhydrophobic aluminum alloy surface,it was known that there was a dense spider web like micro-nano lanthanum oxide rough structures on the surface of the prepared aluminum alloy.In addition,the synergistic effect of rare earth lanthanum oxide intrinsic superhydrophobicity made it exhibit superhydrophobic characteristics.The contact angle with water could reach 160°,and the rolling angle was about 5.0°.And it had good self-cleaning,wear resistance,and corrosion resistance.
