A plating layer obtained by Zn, Al and Mn plating solution has largely improved surface condition and performance compared with a plating layer obtained by pure Zn plating solution and Zn and Al plating solution; the main performances are that zinc ash, zinc slag and the thickness of the plating layer are decreased, and the surface brightness and the corrosion resistance of the plating layer are improved; and the hot dipping process is simple, and is conveniently operated.
Description
Technical field
The present invention relates to ferrous materials protection against corrosion field, be specifically related to a kind of preparation method and immersion of hot dip galvanizing-Al-Mn alloy.
Background technology
In recent years, galvanizing is widely used in ferrous materials protection against corrosion field with its good solidity to corrosion and higher cost performance.Because the movable metallic of metallic zinc is higher, and electropotential is lower than the electropotential of iron, so pure zinc coating has good anodic protection effect, but the galvanized workpiece working life of pure zinc coating is short.In order to improve solidity to corrosion and the over-all properties of coating, researcher proposes and attempts in zinc liquid, adding one or more alloying elements and carry out hot dip process.Experiment is found to add the alloying elements such as rare earth, Bi, Al, Ti, Mg and Mn in zinc is bathed, and can make some performance of coating be optimized or improve, and adds multiple alloying element can obtain the good coating of over-all properties simultaneously.
Sheng Delin effect can cause plating piece to occur the coating of gloomy, super thick, poor adhesion, and zinc consumption increases, and quality product declines.Alleviating or eliminating Sheng Delin effect, obtain the good coating of over-all properties is the expectation of galvanizing industry.
In zinc liquid, add trace of Al, can effectively reduce the generation of zinc gray, cadmia, and zinc liquid mobility increases.In addition, Al and Fe atom have stronger avidity, if zinc adds Al in bathing, at the immersion plating initial stage, steel substrate surface can generate and suppress the Fe-Al intermetallic compound that Fe-Zn grows mutually, makes alloy layer attenuation, can alleviate Sheng Delin effect.Along with Al content in zinc liquid increases, in alloy layer, can in succession generate stable Fe
