摘要： PURPOSE:To form oxide films of superior heat conductivity, heat resistance and electrical insulation characteristic by generating tensile stresses on the surface of a metallic plate in such a way not to develop compressive pressure in any direction and anodizing said surface then treating the same further with a polymerizable org. metallic compd. CONSTITUTION:While the four sides of a metallic plate 1 consisting of Al, Ti, Ta and their alloys are pulled biaxially in parallel to the surface by means of oil hydraulic cylinders 2b via chucks 2a, an electrolyte 4 is filled in a cylindrical body 3 on the surface of the plate 1, and the surface is electrolyzed with the plate 1 as anode and a suitable conductor 5 as cathode, whereby the material 1 is anodized. Both acidic bath and alkali bath are used as the electrolyte 4. After the material 1 is washed 1, tensile stress is relieved, and the anodically oxidized film is further immersed in a soln. prepd. by dissolving a polymerizable org. metallic compd. such as phenyl triethoxysilane in an org. solvent or the like to allow said compd. to impregnate and stick on the micropores and the surface of the oxide film, after which the plate is dried and heated to polymerize the compd.

摘要： PURPOSE:To improve the corrosion resistance of a coating layer and prevent the formation of red rust in exposed parts by treating an Al coated steel wire in heated water of pH of a specific range. CONSTITUTION:An Al coated steel wire is subjected to a boiling treatment in heating water controlled to 8-10pH. Amines, alcohol amine, amides, ammonia and the like are used for this. Thereby, a boemite film is formed on the surface of the coating layer, and the corrosion resistance is considerably improved. The reason for limiting the pH here lies in that below 8pH it is undersirable in terms of passivation effect upon the exposed parts of the steel core. Above pH 10, the dissolution of Al takes place excessively on account of alkalinity simultaneously with boemite film formation, and this is not advantageous in the formation of the boemite film. In this treatment, the exposed parts of the steel core are passive, and are formed with lower oxide such as Fe(OH)2 and FeO, and since these are in a boiling state, they are converted to Fe2O3 of good corrosion resistance and adhesive strength, thereby preventing red rust.

摘要： PURPOSE:To enhance the lubricating property and wear resistance of a porous metallic article by a method wherein a porous metal is delectrolytically treated in an aqueous solution containing a thiomolybdate or a thiotungstate as a main constituent, followed by a heating treatment if necessary. CONSTITUTION:As a porous metal, for example, a metal subjected to porous chrominum plating or microracked chrominum plating, or a plastic material subjected to electroless plating followed by porous chromium plating or microcracked chromium plating is used. When the porous metal is electrolytically treated in an aqueous solution in which a thiomolybdate or a thiotungstate is dissolved, molybdenum sulfate or tungsten sulfate or the sulfide of the porous metal is produced and contained in the pores of the porous metal. After the electrolytic treatment is completed, the porous metal is washed with water and is dried, followed by heating treatment if necessary.

摘要： PURPOSE:To improve lubricity by subjecting a porous anodically oxidized coating to pre-treatment electrolysis in an aqueous soln. contg. metallic salts then to secondary treament in an aqueous soln. consisting essentially of metallic salts of thio acid. CONSTITUTION:Aluminum or its alloy is anodized to form an anodically oxidized coating. This porous anodically oxidized coating is electrolyzed in an aqueous soln. contg. inorg. acids such as nitric acid, phosphoric acid and sulfuric acid or org. acids such as oxalic acid, formic acid and acetic acid as well as their metallic salts, whereby it is half-sealed. Thence, it is subjected to the secondary electrolyzing treatment in the electrolyte dissolved with 1>= kinds of ammonium salts, alkali metallic salts, and alkaline earth metallic salts of thio acids such as thiomolybdic acid, thiotungstic acid, thiostannic acid, thioantimonic acid, thiocupric acid, thioauric acid, thioplatinic acid, thioniobic acid, and thiovanadic acid, whereby metallic sulfides are formed and are deposited in the micropores of the anodically oxidized coating.

摘要： PURPOSE:To improve the lubricating property and corrosion resistance, by secondarily electrolyzing porous anodic oxidation coating of aluminum or its alloy in the aqueous solution dissolved one kind or more of thiotungstate. CONSTITUTION:Porous alumite coating is chemically formed by the anodic oxidation of aluminum or its alloy in the electrolyte, such as sulfuric acid, oxalic acid. Next, secondary electrolysis is performed in the electrolyte dissolved at least one kind or more of thiotangustate after washing by water. (NH4)2WS4, (NH4)WS2O2, K2WS4, K2WS2O, K2WS2O2 etc. are used as thiotangstate. Said coating can be colored of various color tones, such as yellow, light brown, dark brown or colorless, by controlling the quantity of electricity at the secondary electrolysis.

摘要： PURPOSE:To easily manufacture the title body with superior lubricity, hardness, electrically insulating properties and corrosion resistance by dispersing lubricating solid particles in Al powder; sintering the dispersion; and anodic-oxidizing the resulting sintered Al composite body. CONSTITUTION:One or more kinds of lubricating solid particles such as graphite, BN, MoS2 and WS2 are mixed with Al powder while agitating to be dispersed in the powder. The dispersion is then compression-molded into a predetermined shape and sintered with a usual sintering apparatus. The resulting sintered body is optionally worked into a desired shape by cutting or other method, pretreated by usual degreasing, etc., and anodic-oxidized to form a hard anodic oxide film.

摘要： PURPOSE:To well color anodic oxidation film to a blue color by subjecting the anodic oxidation film of an aluminum base material to secondary electrolyis treatment in an aqueous molybdate solution. CONSTITUTION:Al or Al alloy is subjected to anodic oxidation electrolysis treatment to be formed with an anodic oxidation film of a desired thickness. Next, this is subjected to secondary electrolysis treatment in an aqueous acidic solution of molybdate [(NH4)2MoO4, Na2MoO4, etc.]. This electrolysis may be any of AC, DC and AC-DC superposition but in the case of DC, the anode film is made cathode. Electrolysis conditions are made about 0.01 to 1A/dm2 of current density in the case of, e.g., constant current electrolysis and about 2 to 30V in constant voltage electrolysis. Concentrations of the molybdate in the electrolyte are about 1 to 100g/l as Mo and addition of small amounts of one or two or more kinds of boric acid, borate and/or metal salts such as of iron, tin, zinc, etc. besides this is desirable. Thus, the molybdic acid is reduced and colored in the fine pores of alumite, whereby coloring is effected.
