Ultrasonic Arc Spraying Technology of Aluminum Protective Coating on High-Strength Steel Parts of Aircraft

Xia Wei Cheng

Abstract

Based on the bonding strength, porosity and corrosion resistance of spraying aluminum protective coatings on the high\|strength steel parts of aircraft, the optimal technological parameters including arc distance, voltage and arc current were chosen by orthogonal experiment method. When the spraying parameters are the 200 mm, 34 V and 160 A, a better protective coating had obtained.
