Description
Technical field
The present invention relates to a kind of binary alloy coating material and manufacture method thereof, especially a kind of binary alloy coating material of high anti-corrosion plated steel material and manufacture method thereof.
Background technology
On current domestic and international market, because it is increasing in the fields such as household electrical appliances, building materials, automobile to pot galvanize or hot-dip galvanized alloy steel plate demand, but most of producer is still producing and is using traditional hot-dip galvanizing sheet steel (band) or only contain the hot-dip galvanizing sheet steel (band) of 0.1～0.2%Al, promptly so-called binary alloy hot-dip galvanizing sheet steel (band).There are a lot of defectives in this product, work-ing life is short, only 10 years left and right sides time promptly produced the defective of corrosion, and machining property is poor, and coating causes damage easily because of stretching, particularly in that to be higher than under the condition of room temperature etch resistant properties poor, the easy embrittlement of coating and matrix metal junction, easily oxidation generates firecoat, and anti-fatigue performance is poor, after bended several times, be easy to generate be full of cracks, coating decortication phenomenon occurs.
For solving the problems of the technologies described above, prior art proposes a lot of relevant technical schemes, as author Wu Junlin, Yu Zhongxing, in two pieces of articles of " trace additives is to the hot galvanized layer Effect on Performance " that Zhu Yongda delivers on periodical " Shanghai non-ferrous metal " by name and " trace adds the influence of rare earth to the zinc base alloy coating performance ", all mention in temperature zinc layer and to add trace rare-earth element or other elements such as magnesium etc. can play beneficial effect, but these two pieces of articles only stay in learned research, how relate to various concrete elements adds on earth and does not still have final conclusion at present, even as add how many optimums at the additive containing aluminium that has been commonly used described in " trace additives is to the hot galvanized layer Effect on Performance " and still do not have final conclusion, wherein comparatively general viewpoint thinks that the content of Al is too much unsuitable, the situation that the content of unique disclosed Al is bigger in the document is when dosing element silicon, it can be Zn-55%Al-1.5%Si, and introducing interpolation nickel, rare earth, lead and antimony, titanium, in the time of magnesium elements, the content maximum of its disclosed Al be 27% (when dosing titanium elements), this is because various elements are not quite similar to the influence that hot-dip galvanizing sheet steel produced, or even opposite effect, therefore can not simply on the basis of binary (Si-Al) alloy, add other trace elements arbitrarily, although therefore recognized in theory that from science adding some element can play beneficial effect in these two parts of periodical literatures, but still do not provide these elements and add in the binary alloy best proportion of composing to, especially the content of Al is that the best does not have final conclusion yet in how many scopes, therefore present coating material majority still only is made up of binary alloy, do not comprise any other trace element, described as ending up " the research great majority still rest on laboratory stage both at home and abroad at present; have only the minority alloy to be applied to produce " in " trace additives is to the hot galvanized layer Effect on Performance ", therefore, the coating material how to form is pendent technical problem always.
Summary of the invention
At the unfavorable technical barrier of binary alloy coating material performance in the prior art, the object of the invention is to provide a kind of binary alloy coating material and manufacture method thereof of high anti-corrosion plated steel material, corrosion resistance and resistance to elevated temperatures with better raising plated steel material, prolong the work-ing life of steel, improve the surface quality of steel.
Binary alloy coating material of the present invention, wherein said binary alloy is made up of Al and RE, described material also comprises trace additives, described trace additives is selected from one or more among Fe, Ti, B, Pr, Nd, Pb, Cu, Sn, Bi, Ni, the Sb, and described trace additives total content is below 0.5%.
Wherein each composition of preferred described binary alloy accounts for the mass percent of total mass and is: RE:0.1～10%, surplus are Al.
Preferred, the concrete content of wherein said each composition of trace additives, Fe＜0.3%, Ti＜0.1%, B＜0.1%, Pr＜0.1%, Nd＜0.1%, Pb＜0.1%, Cu＜0.1%, Sn＜0.1%, Bi＜0.1%, Ni＜0.1%, Sb＜0.1%.
A kind of method of making binary alloy coating material, described binary alloy is made up of Al and RE, described material also comprises trace additives, described trace additives is selected from one or more among Fe, Ti, B, Pr, Nd, Pb, Cu, Sn, Bi, Ni, the Sb, and described trace additives total content is below 0.5%, after various elements are carried out proportioning according to the above ratio, add melting in the smelting furnace, smelting temperature is 700～850 ℃, through stirring, refining, slagging-off, pour into alloy pig at last.
A kind of high anti-corrosion plated steel material, wherein said high anti-corrosion plated steel material plating binary alloy coating material, described binary alloy is made up of Al and RE, described material also comprises trace additives, described trace additives is selected from one or more among Fe, Ti, B, Pr, Nd, Pb, Cu, Sn, Bi, Ni, the Sb, and described trace additives total content is below 0.5%.
Adopt technical scheme of the present invention, compared with prior art, after adding trace additives, because mass percent by each composition of reasonable configuration, overcome and the element influence each other and the side effect of generation, therefore solidity to corrosion improves greatly, and particularly the solidity to corrosion of swarf is more outstanding.The zinc-plated floor height of coating surface hardness ratio, frictional coefficient is littler than steel plate galvanized, and it is good to add the man-hour sliding, is difficult for producing slide mark.The coating surface light, anti-blackening.Coating not only strengthens with the matrix metal bonding force, and coating surface does not have the dross phenomenon.
Simultaneously, this binary alloy coating material adopts unique prepared, the uniform ingredients segregation-free, remelting or remelting still can keep this effect after placing for a long time, and end slag growing amount is few, high solidity to corrosion and good anti-fatigue performance are arranged, strong with the matrix metal bonding force, can be widely used in household electrical appliances, building materials, automobile industry.
