Abstract

The invention discloses a surface anticorrosive treatment method of aluminium alloys used for auto spare parts. The method is characterized by comprising the following steps: (1) coating aluminium alloy workpieces subjected to rough turning with anticorrosive particle powder, so that the anticorrosive powder is filled in turning grooves, wherein the anticorrosive powder comprises 70-72% of phenolic modified epoxy resin, 4% of triglycidyl isocyanurate, 30% of pigments and silica powder and 3-5% of dispersing agent; (2) pounding the surfaces with an ultrasonic pounding head to mix and refine metals and the anticorrosive powder in the turning grooves of the workpieces, thus forming anticorrosive layers of the surfaces of the aluminium alloys, wherein the range of the ultrasonic frequency is 70kHz and the power is 600W. The surface anticorrosive treatment method has the beneficial effects that the surface treatment method is reasonable in innovation and concise in process; the formed anticorrosive layers are conducive to improving the corrosion resistance and insulativity of the materials; the surface hardness of the workpieces is increased by adopting the process, so that the auto spare parts have stable states and long service lives; therefore the surface anticorrosive treatment method is worthy of being popularized.
