摘要： PURPOSE:To form a paint film free from the trace of a roll by a method wherein a wet paint film is covered with a paint film smoothing plate member before its drying and this member is pressed with a pressing roll. CONSTITUTION:After painting a strip-like body 5, a wet paint film 8 is covered with a paint film smoothing plate member 6 before its drying. The paint film smoothing plate member 6 is then pressed from above with at least one pressing roll 7, whereby the surface of the wet paint film 8 is also pressed while being leveled by the paint film smoothing plate member 6.

摘要： PURPOSE:To obtain the title coating easy to handle, capable of giving, in high processability, coating film of uniform and high hardness on matrix steel plates by melting, through heating, a poorly soluble polyester resin together with a crosslinking agent and by dissolving the resultant mixture in an organic solvent at a specified concentration. CONSTITUTION:(A) 100 pts.wt. of a poorly soluble polyester resin (e.g. 3000-20000 in molecular weight) and (B) 10-40 pts.wt. of a crosslinking agent (e.g. epsilon- caprolactam-blocked isocyanate) are heated at temperatures e.g. not higher than the dissociation temperature of said blocked isocyanate and melted to obtain a homogeneous mixture. This mixture is then dissolved in (C) an organic solvent so as to be >=10wt.% in the concentration of the component A, thus obtaining the objective coating. This coating is applied on the substrate film on a cold-rolled or zinc-plated steel plate provided with phosphate or chromate treatment to obtain the other objective coated steel plate excellent in processability.

摘要： PURPOSE:To obtain a blast material capable of producing a surface-treated metallic material having excellent adhesive property and corrosion resistance by coating the Fe or Fe alloy as the core with a Zn-Al alloy layer having a specified composition through a Fe-Zn alloy layer. CONSTITUTION:The Fe or Fe alloy as the core is coated with a Zn alloy layer consisting of 40-65wt.% Al, the balance Zn, and inevitable impurities through an Fe-Zn alloy layer. The coating is obtained by charging Fe powder, etc., into the molten Zn alloy having the above-mentioned composition, and the Fe-Zn alloy layer is inevitably formed as the intermediate layer between both layers. The blast material is formed from the aggregate of the independent double-layer particles thus obtained. The blast material is blasted, deposited and formed a coating film on the surface to obtain the highly corrosion-resistant metallic material. In this case, the blast material is continuously projected onto the surface of the metallic material, and the projecting rate is preferably changed and reduced during the projection. The atmosphere for projecting the blast material or the blast material itself is desirably heated to about 5-300 deg.C for the projection.

摘要： PURPOSE:To provide a titled joint provided with excellent resistance to seizure by forming one kind among Cr, Mo and W alloys for the uppermost layer and a soft metal having low hardness and easy plastic deformability for the lower layer by multi-layer plating to specific thicknesses at a screw or metal sealing part. CONSTITUTION:A soft metal such as Cu, Zn, Sn, Pb or the like of >=2mu which has low hardness and is easily plastically deformable is plated for the lower layer of the screw or/and metal sealing part of an oil well pipe for which high airtightness is required and which is tightly screwed. One kind among Cr, Mo and W alloys is plated to a thickness of =50mu, the plating is likely to be peeled. If the hard layer is >=1/2 the entire plating layer, the part for absorbing plastic deformation is smaller. If the soft layer is

摘要： PURPOSE:To effectively prevent the oxidation loss of steel products over a long term by chromating in environment kept at a high temp. by bringing the steel products into contact with an aqueous soln. contg. a specified amount or more of Cr in the form of CrO4 or Cr2O7 at a presribed temp. under a pressure above the pressure of satd. steam at the temp. CONSTITUTION:Steel products are brought into contact with an aqueous soln. contg. >=0.0001g equiv./lCr in the form of CrO4 or Cr2O7 in environment kept at a high temp. such as 150-350 deg.C under a pressure above the pressure of satd. steam at the temp. The aqueous soln. includes an aqueous soln. contg. 50g/l CrO3 and 45g/l Fe(OH)2. By the chromate treatment at high temp. and pressure, thick Cr-enriched coats are formed on the surfaces of the steel products. The Cr-enriched coats can effectively prevent the oxidation loss of the steel products over a long term.
