The invention belongs to the field of environment-resistant design of sensors for aircrafts, and particularly relates to a method for preventing corrosion of an icing detector probe. At present, domestic aircrafts with icing detection functions are used by the army and the air force, but the navy model aircrafts are required to meet the requirements of an acid-resistant atmosphere and an acidic salt fog environment. At present, icing detector probes used in the army and the air force equipment do not take this respect into consideration and cannot be used directly. The method adopts chemical nickel plating to plate a nickel layer on the surface of a vibrating head, and the thickness of the nickel layer is no less than 14 microns. By means of the method, the protective capability of the icing detector probe under marine environment-resistant (including acidic salt fog and acidic atmosphere) conditions is enhanced, the service life and reliability of the icing detector probe are improved, and the defect that icing detector probe body materials can not satisfy use requirements under marine environmental conditions is overcome.
