Definitions

  • the present invention relates to a shot material used in mechanical plating for forming a high corrosion resistant coating on a metal material surface, and to a high corrosion resistant coating formed using the shot material.
  • Zinc based coating Forming a zinc or zinc alloy coating (referred to hereinbelow as "zinc based coating") on iron-based metal materials is a widely-used method of improving the corrosion resistance of the iron-based metal. Specific technologies for this that are in practical industrial use include hot dipping, phosphate plating, electroplating, and mechanical plating.
  • zinc based coating formed by zinc plating or the like If zinc based coating formed by zinc plating or the like is exposed to the air without first being treated, it can give rise to white rust of the zinc in a relatively short time, expediting deterioration of the coating. This is especially pronounced in an outside environment. To prevent that happening, a treatment such as chromating is used to form a protective coating on the zinc based coating.
  • a zinc based coating formed by mechanical plating has a layered, flaky structure like a pie crust, structure, when it is subjected to chromate treatment, the chromate solution can fully permeate the coating, providing a good improvement in the corrosion resistance.
  • the use of chromate treatment increases the time until red rust appears to around 3000 hours, providing a dramatic improvement in corrosion resistance.
  • Chromate treatment is widely used because it facilitates the formation of a coating that provides good protection at a relatively low cost.
  • the solution used for the treatment contains hexavalent chromium, which is toxic.
  • hexavalent chromium which is toxic.
  • the protective effect of such coatings is inferior to that provided by a hexavalent chromate coating.
  • One reason for this is that the other coatings do not have the self-repairability exhibited by a hexavalent chromate coating. That is important, because there is a sharp decrease in the corrosion resistance of locations that suffer damage.
  • Another drawback with methods that do not use hexavalent chromium is that the administration of the treatment solution is complicated and can readily give rise to post-treatment variations in characteristics, making the treatment quite costly compared to the hexavalent chromate treatment.
  • JP 65-119101 A (Reference No. 1), JP 56-93801 A (Reference No. 2) and JP 57-110601 A (Reference No. 3) disclose the use of powders of zinc alloy in which aluminum, magnesium and the like are used as alloying elements. Also, in order to improve the durability of such zinc based coatings, it is important to improve the bonding of the coating to the base metal.
  • EP 1 193 323 A which relates to a galvanized plated steel product.
  • EP 0 177 786 A describes an Anti-corrosion treatment process for iron materials, in which a zinc coating is formed by mechanical zinc plating using a shot material.
  • the object of the present invention is to provide a zinc based coating formed by mechanical plating that itself has a markedly improved corrosion resistance that does not rely on protective coating formation treatment such as chromate treatment or the like.
  • a shot material for mechanical plating comprises steel core particles clad with an alloy comprising 1 to 5% by weight of aluminum, 3 to 15% by weight of magnesium, preferably 5 to 15% by weight of magnesium, and the balance, of zinc and unavoidable impurities.
  • the unit of "% by weight” pertains to the same meaning as those of "% by mass” in the present specification.
  • the alloy may contain a total of up to around 1% by weight of impurities.
  • An Fe-Zn alloying layer may be provided between the alloy cladding and the steel core.
  • the shot material may contain 3 to 80% by weight of iron.
  • the shot particles have an average diameter of 100 to 600 ⁇ m.
  • the invention also provides a high corrosion resistant coating having a thickness of 2 to 15 ⁇ m formed on a surface of metal material such as steel or the like by projectblasting the above shot material, the high corrosion resistant coating comprising 1 to 5% by weight of aluminum, 3 to 15% by weight of magnesium, up to 20% by weight of iron, and the balance of zinc and unavoidable impurities.
  • the coating may contain a total of up to around 1% by weight of impurities.
  • the corrosion resistance of parts having the coating as formed by mechanical plating is dramatically improved.
  • by increasing the magnesium content in the zinc based alloy cladding layer constituting the shot material it is possible to obtain iron-based parts having a very high corrosion resistance, as indicated in the salt spray test by a time for red rust to be produced that exceeds 4000 hours.
  • the present invention utilizes a novel corrosion resistance improvement effect produced by the synergism of i) and ii). At present the mechanism that brings about this synergy has not been fully clarified.
  • the formed coating preferably contains 1% or more by weight of aluminum. However, if the amount exceeds 5% by weight, it will not be expected to produce an effect corresponding to the amount added.
  • the composition of the alloy cladding around the steel core of the shot material more or less is a reflection of the composition of the coating formed on a part, and as such, the aluminum content in the alloy cladding layer of the shot material is set at 1 to 5% by weight.
  • magnesium forms oxides and hydroxides.
  • Magnesium oxides or hydroxides have high electrical insulation properties that suppress corrosion current produced when the zinc in the coating corrodes. It also prevents oxygen permeation, thereby exhibiting a protective effect with respect to zinc corrosion.
  • Magnesium has a lower electric potential than zinc, but in a corrosive environment produces stable corrosion products and alleviates the galvanic action of zinc. It is thought that this controls the elution of the zinc in the coating, elevating the corrosion prevention effect. Through detailed studies, the inventors found that these effects of magnesium became apparent when the magnesium content in the coating was 3% or more by weight. A magnesium content of 5% or more by weight is preferable.
  • the magnesium content is set at 3 to 15% by weight.
  • the magnesium content is 5 to 15% by weight, and more preferably 7 to 12% by weight.
  • a coating formed by mechanical plating contains iron from the shot material or parts concerned. Good results can be obtained with an iron content range of up to 20% by weight, such as, for example, from 0.1 to 20% by weight. It is desirable to keep the total content of impurity elements (elements other than zinc, aluminum, magnesium and iron) to not more than 1% by weight.
  • This invention uses shot particles that have a steel core. That is, the particles are composite particles consisting of steel particles and zinc based alloy. Blasting the surface of the material to be treated with these composite-structure particles provides as good a coating adhesion as those of conventional shot material having an iron core.
  • a coating material composition to which is added an Al-Mg composite having a high magnesium content That is, it brings forth the synergism of i) and ii), which is not something that could be predicted before.
  • the impact of the steel-core shot particles strengthens the adhesion bonding of the coating to the base metal and also strengthens the coating itself, increasing the damage resistance of the coating.
  • the sealing effect of the aluminum in the cladding material combines with zinc elution prevention effect provided by elevating the magnesium content, generating the major improvement in the corrosion resistance.
  • the ratio between the steel particle core and the zinc based alloy cladding layer should be controlled so that the content of the iron in the shot material is from 3 to 80% by weight. If the iron content is lower than that, it is difficult to obtain a sufficient impact energy, while a higher content will result in a relatively small amount of cladding material, shortening the life of the shot material during the blasting process of the mechanical plating.
  • steel cores having a hardness in the order of 200 to 700 HV At least 95% by weight of all shot particles should have a particle diameter that falls within the range 10 to 800 ⁇ m, and an average diameter of 100 to 600 ⁇ m.
  • the coating formed on the surface of the subject metal material has to be at least 2 ⁇ m thick.
  • using mechanical plating to form a coating with a heavy coating weight that exceeds 15 ⁇ m in thickness is uneconomical.
  • a good corrosion resistance effect can be obtained by controlling the coating thickness to be within the range of about 2 to 15 ⁇ m.
  • the shot material of the invention can be manufactured by the steps of preparing a zinc alloy melt having a composition corresponding to the material used to clad the steel core particles, charging the steel core particles into the zinc alloy melt, stirring the mixture, removing it when it cools into a semi-solidified state, crushing and screening.
  • the amount of the zinc alloy melt and the charging amount of the steel particles charged into the melt should be controlled to bring the iron content in the shot particles to within the range of 3 to 80% by weight.
  • an Fe-Zn alloy layer forms at the interface between the steel particles and the zinc alloy.
  • the Fe-Zn alloy layer is relatively brittle, so when the shot material is impacted on the surface of subject material to be treated in the blasting process, the microparticles of zinc alloy sheared-off finely in the portion of the Fe-Zn alloy layer are pressed onto the surface of the subject material, increasing the uniformity of the coating.
  • the alloy-clad shot particles should have a diameter within the range 10 to 800 ⁇ m.
  • the average particle diameter should be within the range 100 to 600 ⁇ m, and may be within the range 100 to 400 ⁇ m or 150 to 300 ⁇ m. Since the iron content of the shot particles is preferably from about 3 to 80% by weight, the size and quantity of the steel particles used should be set in accordance with those target values.
  • the shot materials obtained had an average diameter of 218 ⁇ m. Based on observation of the cross section of the particles using electron dispersive x-ray spectroscopy (EDS), the steel particles were seen to have cores originating from the steel shot, which were clad by a layer of zinc alloy via an alloy layer formed by the reaction between the steel shot and the melt. Further analysis of the section showed the alloy layer formed by the reaction between the steel shot and the melt to be an Fe-Zn alloy layer, and the zinc alloy cladding layer to have a composition corresponding to the composition of the initial melt. Shot sample composition analysis conducted using the method for the determination of total iron content in iron ore of JIS M-8212-1958 and the potassium permanganate titration method showed the shot material to have an iron content of 49.9% by weight.
  • EDS electron dispersive x-ray spectroscopy
