Description
Technical field
The present invention relates to a kind of micro-alloying hard zinc alloy, belong to the manufacturing technology field of metalwork surface treatment and metallic film capacitor end face metal spraying material.
Background technology
Shot-peening has been widely used in the surface-conditioning of metal parts, the tradition shot-peening is the silica sand particle, can remove all impurity in metalwork surface up hill and dale, as oxide skin, corrosion and old paint film, have rust cleaning efficient advantages of higher, but produce a series of problems in the process of sandblast: the shot-peening repeat usage is low; Produce a large amount of harmfully and operating environment had the silicic acid dust of pollution in treating processes, this dust is easy to cause silicosis in case sucked by human body, and also trouble of on-the-spot cleaning.This in recent years shot-peening is limited to use gradually, and use substantially abroad is under an embargo.
Use now the more general materials such as stainless steel, carbon steel, aluminium, zinc that have, make the silk of 0.5-1.5mm diameter, cut into particle again, as shot-peening.Existing zinc ball is mainly used in and cleans non-ferrous metal precision casting surface, and (HV 28-32) is moderate for its hardness, can remove the impurity such as burr, oxide compound of cast(ing) surface under the prerequisite of not destroying cast(ing) surface.Precision casting surfaceness precision after the cleaning is higher, particularly can form the zinc metallic membrane of one deck 0.0013mm thickness in the process of cleaning at piece surface, in the climatope of humidity, can play interim etch-proof effect.The dust that the zinc ball produces is less, and dust can not splash everywhere.Dust explosion, danger on fire are extremely low, are the higher shot-peenings of comparison environmental protection and safety performance.But because of yielding fragmentation, its repeating utilization factor is lower, and the relative price cost is higher, gives and uses producer to bring cost pressure.
Along with improving constantly of the zinc prices of raw and semifnished materials, the zinc ball is wished under the constant substantially situation of use properties in market, suitably increase its hardness (〉=HV32), to improve repeating utilization factor.
In metalwork anti-corrosion spray and metallic film capacitor end face metal spraying industry, in order to improve operating efficiency, progressively using the high-performance spray gun at present, making distance and wire feed rate increase between wire feeder and the nozzle, this kind spray gun uses existing zinc wire material (tensile strength＜120N/mm
2) time, under the effect of wire feeding force, very easily make crooked generation of silk block up rifle.Zinc the silk (〉=120N/mm that has a kind of tensile strength higher wishes in market
2).
Summary of the invention
The purpose of this invention is to provide and a kind ofly can effectively improve tensile strength and hardness, satisfy the micro-alloying hard zinc alloy of metalwork surface treatment and the requirement of capacitor end surface metal spraying.
The present invention is a micro-alloying hard zinc alloy, with zinc is matrix, it is characterized in that also comprising simultaneously nickel, and the composition of each component is respectively by weight percentage: nickel 0.001-0.5%, all the other are not more than 0.1% impurity for zinc and total amount, and the weight percent summation of each component is 100%.
Also can add magnesium in the described micro-alloying hard zinc alloy, its add-on is the 0.001-0.1% of each component total weight percent, preferably can be 0.002-0.08%.
The content of described nickel preferably can be the 0.003-0.3% of each component total weight percent.
The composition of each component can be respectively by weight percentage in the described impurity: plumbous≤0.03%, cadmium≤0.002%.
Described micro-alloying hard zinc alloy can comprise zinc ball or zinc silk.
Microalloying is a kind of metal material processing technology that develops rapidly in recent years; it mainly is the trace element that adds other in matrix metal; to obtain specific mechanical property; this technology has efficiently, saves characteristics such as alloying element; be acknowledged as " environment protection material "; and pure zinc (Zn) is a kind of non-cold working hardening metal, and different complete processings can not change its mechanical property.The present invention utilizes the microalloying principle, by adding the nickel and the magnesium of trace, can improve its mechanical property significantly.
In pure zinc (Zn), add nickel (Ni), but the crystal grain in the refinement alloy graining tissue, effectively improve the mechanical property of alloy, if but nickel content less than 0.001%, its effect is not clearly, when content surpasses 0.5%, its ability that improves mechanical property is on a declining curve, and cost rises, and therefore takes all factors into consideration and compares, the present invention determines that nickel content is 0.001%-0.5%, and preferred content is: 0.003%-0.3%.
Discover the magnesium (Ma) that in alloy, adds trace, can further improve hardness of alloy and tensile strength, and still can keep alloy that higher unit elongation is arranged, if but Mg content was less than 0.001% o'clock, it increases the alloy rigidity effect is not fairly obvious, when the content of magnesium surpasses 0.1%, tensile strength sharply increases, and descending appears in unit elongation, too high tensile strength also is unfavorable for the use of spray gun, therefore take all factors into consideration and compare, the present invention determines that Mg content is 0.001-0.1%, and preferred content is 0.002%-0.08%.
The present invention stipulates that the weight percent of total impurities less than 0.1%, considers unleaded requirement, and in the impurity of the present invention: plumbous (Pb)≤0.03%, cadmium (Cd)≤0.002%, other element kind and component are not done requirement.
Studies show that the trace element that the present invention added in scope of design of the present invention, can not produce detrimentally affect to metallic film capacitor.
The present invention can provide the micro-alloying zinc ball of different hardness and tensile strength according to the difference of processing metalwork; Also can provide the micro-alloying zinc silk of corresponding tensile strength, to solve stifled rifle problem according to the spray gun of different model.Can replace traditional zinc ball and zinc silk product in fields such as metalwork surface treatment, anticorrosion with painting, metallic film capacitor end face metal sprayings.Through practical application, has following character: tensile strength: 〉=120N/mm
2, hardness: HV32-180, unit elongation: 〉=30%.
