Construction method of marine life preventing coating of transducer

The invention relates to the technical field of marine engineering equipment protection, in particular to a construction method of a marine life preventing coating of a transducer. A piezoelectric ceramic block (1) is included, one end face of the piezoelectric ceramic block (1) is coated with a first silver layer (21), and the other end face, opposite to the end face coated with the first silver layer, of the piezoelectric ceramic block (1) is coated with a second silver layer (22). The construction method is characterized in that the length of the first silver layer (21) is smaller than that of the second silver layer (22), and the length of the first silver layer (21) is 0.35 to 0.5 time that of the second silver layer (22). The construction method of the marine life preventing coating of the transducer is applied to the marine engineering equipment protection technology, and the time of the transducer in water can be prolonged through the construction method.
