摘要： Defects in an initial protective coating, particularly a conversion coating, on a metal substrate can be touched up so as to at least equal the original coating in corrosion protection by use of a dry-in-place aqueous acidic liquid comprising: fluorometallate anions; a component selected from the group consisting of phosphorus-containing inorganic oxyanions and phosphonate anions; and an oxidizing agent, preferably a mixture of hexavalent and trivalent chromium. Other preferred optional active ingredients include free fluoride ions, which stabilize the fluorometallate ions against the formation of precipitates, and a fluorinated surfactant. The same composition also forms an effective protective coating over previously uncoated metal, particularly aluminum. The compositions do not contain any substantial amount of silica, which has often been previously used in compositions for similar purposes.

摘要： Heating an aqueous mixture of a fluoroacid such as H2TiF6 and an oxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long term stability against settling of any solid phase, even when the oxide, hydroxide, or carbonate phase before heating was a dispersed solid with sufficiently large particles to scatter light and make the mixture before heating cloudy. The clear mixture produced by heating can be mixed with soluble hexavalent and/or trivalent chromium, and preferably also nitrate and chloride ions to produce a composition that provides a conversion coating with good protection against corrosion while requiring substantially less chromium than previous coatings of equal corrosion protective quality.
摘要翻译：加热含氟酸例如H 2 TiF 6和氧化物，氢氧化物和/或碳酸盐例如二氧化硅的含水混合物产生清澈的混合物，即使在加热之前氧化物，氢氧化物或碳酸盐相在加热之前具有防止任何固相沉降的长期稳定性是具有足够大颗粒的分散固体以散射光并使混合物在加热之前变浑浊。通过加热产生的透明混合物可以与可溶的六价和/或三价铬以及优选还有硝酸盐和氯离子混合以产生组合物，该组合物提供具有良好的抗腐蚀保护的转化涂层，同时需要比先前的等腐蚀涂层少得多的铬保护质量。

摘要： There is disclosed a treating process whereby the thermal oxidation resistance on the shiny side of a copper foil is enhanced so that the shiny side will not discolor on heating to higher temperatures than usual, without impairing the foil's solder wettability, adhesion to resist, and other properties. A Zn-Ni alloy layer which comprises 50-97 wt% Zn and 3-50 wt% Ni or a Zn-Co alloy layer which comprises 50-97 wt% Zn and 3-50 wt% Co is formed on the shiny side of a copper foil at a deposition quantity of 100-500 µ g/dm² and then the alloy surface is treated for Cr-base corrosion-preventive coating. The Cr-base corrosion-preventive treatment comprises (1) a treatment for forming a coating film of chromium oxide alone, (2) a treatment for forming a mixed coating film of chromium oxide and zinc and/or zinc oxide or (1) + (2). The roughened side of the copper foil may be treated to form thereon a layer of single metal or alloy of two or more metals chosen from among Cu, Cr, Ni, Fe, Co, and Zn. The shiny side does not cause discoloration upon exposure to high-temperature conditions of 240 °C for 30 minutes or 270°C for 10 minutes.

摘要： Method of manufacturing chemically-colored stainless steel materials which are used widely as building materials, and an apparatus for continuously manufacturing the same materials. The colored steel material manufacturing method according to the present invention is characterized in that, using a coloring electrolyte which contains ions containing a metal taking a plurality of valences, a stainless steel material is subjected to the alternating current electrolysis or to an electrolysis treatment after the stainless steel material has been immersed in the electrolyte under conditions according to the electrolyte in use. This method enables the production of multicolor stainless steel materials of a uniform tone by one treatment liquid and one manufacturing step. The apparatus for continuously manufacturing colored stainless steel materials according to the present invention is capable of manufacturing multicolor stainless steel materials industrially and continuously by using one treatment liquid and carrying out one manufacturing step without carrying out any troublesome operations; and controlling the tone with ease by a simple method.
