摘要： 1,272,118. Coating with Al: electro -depositing Cr/Cr oxides. KAWASAKI SEITETSU K. K. Sept. 26, 1969 [Sept. 27, 1968], No.47590/69. Headings C7B and C7F. Steel sheet is coated with a first coating containing at least 2mg/m 2 of metallic Cr and mainly consisting of hydrous chromium oxides by electrolytic treatment in an electrolyte containing hexavalent Cr, and is then coated with Al by vapour deposition. The first film is typically applied by electrolysis in a CrO 3 /H 2 SO 4 bath using a current of 5-30 A/dm 2 , giving a film containing 2-300 mg/m 2 metallic Cr and 4-160 mg/m 2 Cr as hydrous chromium oxides. The thus-coated article is optionally heated to 150-400C., and a layer of Al, preferably 0À05-0À5 Á thick, is vapour deposited thereon to give a corrosion resistant article.

摘要： Tin-free steel sheets having intimately bonded metallic chromium and hydrated chromium oxide coatings thereon and possessing improved resistance to retorting treatment and improved adhesion to paint films to be applied thereon are produced by chromium plating a steel sheet in a chromium plating bath containing an assistant to deposit and form metallic chromium and hydrated chromium oxide coatings on the sheet surface, subjecting the sheet to reverse electrolysis in the same chromium plating bath to partially dissolve away the metallic chromium and hydrated chromium oxide coatings together with the assistant anions codeposited in the hydrated chromium oxide coating, rinsing the sheet with water, and thereafter subjecting the sheet to an electrolytic chromate treatment in an electrolytic chromate treating bath.

摘要： PURPOSE:To improve the adhesive strength between a metallic Cr film and a Cr hydrous oxide film as well as between the Cr hydrous oxide film and paint by plating the surface of a tin-free steel plate for retort treatment in a Cr plating bath then electrolyzing the same reverse and further subjecting the steel plate to an electrolytic Cr acid treatment in a Cr acid treatment soln. CONSTITUTION:In the production of a tin-free steel plate for retort treatment, first it is plated in a Cr plating bath, whereby Cr plating layers of 20-200mg/ m metal per one surface is formed. Next, this is subjected to reverse electrolysis in this Cr plating bath, whereby the Cr hydrous oxide formed during Cr plating and the Cr plating assistant anions therein are eluted. After the steel plate is thoroughly washed, it is subjected to an electrolytic C acid treatment in an aq. Cr acid soln., whereby a Cr hydrous oxide film of 5-50mg/m is formed. When painting is coated on this surface, the adhesive strength between the metallic Cr plating layer and the Cr hydrous oxide film and between the hydrous oxide film and paint is improved and retort treatment resistance is improved.

摘要： PURPOSE:To integrally form a neck, shell and bottom parts and to obtain the strength and corrosion resistance of a can shell by subjecting a specific Al coated steel plate to a drawn ironing, press forming and necking-in as well. CONSTITUTION:A specifically treated steel plate is used for increasing the Al film adhesion of the Al coated steel plate of a blank to be offered for processing a can, preventing the Al separation and preventing the swell generation of the Al film. It is what the Al film in 5-80mum thickness is formed by plating which one kind among 0.01-0.3mum Zn, 0.01-0.3mum Zn-Ni alloy, 0.005-0.5mum Cr, and 0.1-1mum Mn on both faces of the steel plate, heating, rolling and reheating by sticking an Al powder in layers thereon or rolling, heating, rerolling and reheating. The shell part 1' of a bottomed hollow body whose one end is an opening end 6 and whose the other end a closed end 2 is formed with the drawn ironing of this Al coated steel plate and a concave spherical bottom part 4 is formed by press forming to integrally form a neck part 3 by necking-in.
