Abstract

The invention discloses an aluminum alloy surface titanium plating treatment method, and relates to the technical field of aluminum alloy material surface treatment. The treatment process comprises: (a) deoiling; (b) dewaxing; (c) anodic oxidation; (d) acid etching; and (e) titanium plating; and titanium plating treatment liquid is prepared by the following raw materials in parts by weight: 20-35 of potassium chloride, 10-20 of titanium potassium oxalate, 2.5-5.5 of dimethyl carbonate, 5-10 of titanium sulfate, 1-3 of potassium carbonate, 3-7 of methyl butynol, 1-3 of nickel sulfate, 2-5 of butynediol, 1-2.5 of adenine corrosion inhibitor, 0.25-1 of neodymium chloride, and 2-8 of hydroxyethyl acrylate. The method capable of forming a layer of titanium film with high hardness and corrosion resistance on the surface of an aluminum alloy has such characteristics as high efficiency, simple operation and capability of improving the quality of aluminum alloy products, can be used for treating aluminum alloy profiles, also can be used for treating aluminum alloy parts, and in particular, is suitable for treating aluminum alloy shell parts and aluminum alloy panels.

Description

technical field [0001] The invention relates to the technical field of aluminum surface treatment, in particular to a method for treating the surface of an aluminum alloy with titanium plating. Background technique [0002] Because aluminum alloy is light in weight, low in cost, easy to process and shape, and easy to color and dye, it has been widely used. However, restricted by the physical and chemical properties of metal aluminum itself, its surface hardness is low, and it is prone to scratches or scratches. Although in recent years, some imitation titanium aluminum alloy profiles have appeared on the market, the surface is golden yellow, and the hardness is slightly higher than that of conventional aluminum alloy profiles, but compared with stainless steel or titanium materials, its hardness and corrosion resistance Sex etc. are still far apart. For this reason, some titanium-plated materials have appeared on the market, that is, a layer of titanium film with high hard...
