Preparation method of super-hydrophobic aluminum or aluminum alloy surface

摘要: The invention relates to a preparation method of super-hydrophobic aluminum or alloy surface. comprises the following steps: (1) washing, namely washing by acetone and ethanol in sequence under normal temperature pressure remove oil stains from surface so as obtain clean alloy; (2) roughening surface, processing water solution containing sodium metaaluminate urea roughen surface; (3) hydrophobizing, performing chemical vapor deposition on processed step at 120-150 DEG C, modifying with hydrophobic compound According method, used process is simple, operation convenient, industrialization easy realize; surfaces parts special complex shapes can be subjected modification large area; contact angle an obtained coating more than 150 degrees; application prospect wide.
