description The invention discloses a method for detecting an arc burn defect on the surface of a titanium alloy part, and belongs to the technical field of arc burn detection.The method comprises the steps that firstly, an induction coil influence area on the surface of the titanium alloy part is deoiled, and because oil stains on the surface of the part are not thoroughly deoiled, the surface of the part is not wetted by a solution, and therefore, the inspection of the surface arc burn cannot be realized. Oil removal is used for preparing for subsequent electric arc burn inspection, namely, a clean surface capable of reacting with a burn inspection solution is provided. A chemical method is adopted to inspect an area where electric arc burn easily occurs, and any part with electric arc burn can be effectively identified and eliminated, so that the reliability and the safety of an engine are ensured. Parts with burn defects are prevented from being installed in the aero-engine, and the fatigue fracture failure fault of
