摘要： PURPOSE:To improve the lubricity of Ti or a Ti alloy, to facilitate the cold working and to prevent the seizing by immersing the metal in an acidic zinc phosphate soln. for chemical treatment and forming a zinc phosphate film on the surface of the metal by electrolysis as the cathode. CONSTITUTION:Ti or a Ti alloy is previously treated with an aq. soln. of a colloidal Ti type surface treating agent as required. The metal is immersed in as acidic zinc phosphate soln. for chemical treatment and a zinc phosphate film is formed on the surface of the metal by electrolysis as the cathode. The zinc phosphate soln. is an aq. soln. contg. zinc primary phosphate as an essential component ad having a long service life. The proper concn. of zinc ions in the soln. is about 1-50g/l and that of phosphate ions is about 3-140g/l (expressed in terms of PO4). The electrolysis is carried out with zinc or the like as the anode for about 10sec-5min at about 30-80 deg.C, about 5-30cm interval between the electrodes and about 0.2-30A/dm current density to deposit zinc phosphate by about 2-20g/m . A conventional lubricant is then applied to the formed film and cold working is carried out. Thus, a product having a fine finished surface is easily and stably obtd.

摘要： PURPOSE:To attain seizing prevention, thereby improving work efficiency, the the use of a lubricating oil having a predetermined viscosity and comprising a base oil, a sulfur-contg. high-pressure additive of low-temp. decomposable type and a thickening agent in the cold drawing process in which the decrease ratio in cross-sectional area exceeds a particular value. CONSTITUTION:A lubricating oil having a viscosity of 100-5,000cP at 40 deg.C is prepd. by blending 10-60wt% base oil (e.g., rape seed oil), 60-100wt% sulfur- contg. high-pressure additive of low-temp. decomposable type, i.e. a dialkyl polysulfide and 35wt% or less thickening agent (e.g., polymethacrylate). Then, a wire or pipe made of iron or its alloy is washed with an acid, followed by lubricating treatment using the above-mentioned lubricating oil, and subjected to cold drawing so as to allow the decrease ratio in cross-sectional area to 30% or more. Further addition of a sulfur-contg. high-pressure additive of high- temp. decomposable type (e.g., sulfurized lard oil) to the lubricating oil enables the effective lubrication of the lubricating oil to be maintained even at high temps.

摘要： PURPOSE:To increase chemical conversion coating efficiency, reduce the sludge to be produced and substrate surface roughness and form a chemical film with good serizing resistance roughness by limiting the composition of a chemical conversion coating soln. CONSTITUTION:An aq. soln. contg. 0.10-1.00mol/l of manganese ion, =10mg/m when the seizing resistance is important, and ions of metals such as nickel, cobalt and copper are added to the processing soln. to increase the film weight. The coating is applied at 50-90 deg.C.

摘要： PURPOSE:To form a good underlying film for painting without requiring a plating liquid by forming a Zn film by a shot blasting method on the surface of steel products then treating the film with a phosphate treating liquid contg. Ni ions. CONSTITUTION:The pulverized particles of a Zn (alloy) coating metal such as Zn or An alloy are sprayed by the shot blasting method to the surface of the iron and steel products to form the film of the Zn (alloy) at the same instant when the oxide films such as rust and black skins on the surface of the steel products are removed. The film is thereafter subjected to the surface prepn. using an aq. soln. of colloid titanium according to need. The film is then treated by using the phosphate treating liquid added with about 0.05-10g/l Ni ions to form the phosphate film thereon. The spacings among the pulverized particles of the Zn (alloy) are filled by the phosphate crystals and the film having the good corrosion resistance is formed as the subtrate for painting by the above- mentioned treatment method.

摘要： PURPOSE:To perform easily the drawing under strict conditions and the removal of the coating after the working by coating a lubrication oil after forming a film by drying with coating on the metal the resin water solution containing a poly-denatured vinyl acetate and polyhydric alcohol. CONSTITUTION:The poly-denatured vinyl acetate in the water solution having about 200-3,000 polymerization degrees and >= about 65% saponification degrees is used. There are various kinds of glycols as for polyhydric alcohol cut it is glyceline that has good compatibility and is preferrable. The mixture ratio of the poly-denatured vinyl acetate and polyhydric alcohol is preferrably 100/1-100/50. The resin film quantity on the metal surface is taken as 0.1-5g/m . The lubrication oil to be coated on the film of oils and fats or mineral oil base is used but it is preferrable to use the ubrication oil containing the reactant of aliphatic diamine and aliphatic and/or acidic alkylphosphoric ester. The forming with drawing under the strict conditions can thus be performed and the residual film on the metal surface can easily be removed as well.
