摘要： PROBLEM TO BE SOLVED: To provide a steel sheet for electrogalvanizing in which the occurrence of unevenness caused by the surface defects of an original sheet after plating can be prevented, and to provide a method for producing an electrogalvanized steel sheet which has no surface defects such as unevenness and has excellent surface appearance.
SOLUTION: In the steel sheet for electrogalvanizing, a layer changed in properties is present on the surface, and the area ratio of the layer changed in properties occupied in the surface is ≥80%. The steel sheet for electrogalvanizing is produced by projecting fine particles on the surface of the steel sheet, and thereafter applying electrogalvanizing to the steel sheet. The mean particle diameter of the fine particles to be projected is preferably controlled to 10 to 300 μm. Further, the projection velocity of the fine particles is preferably controlled to ≥30 m/s, and the projection density of the fine particles to 0.2 to 60 kg/m

摘要： PROBLEM TO BE SOLVED: To obtain an electrogalvanized steel sheet free from surface defects such as unevenness and high in whiteness by forming an electrogalvanizing layer on a tin layer of a specified precipitating amt. formed on a steel sheet by pickling. SOLUTION: The precipitating amt. of tin formed by pickling is 0.5 to 10 mg/m2. At first, a steel sheet is passed through a pickling soln., and pretreatment to plating is executed. The picking soln. has been added with tin sulfate, e.g. by 0.1 to 20 g/l, and tin is precipitated onto the surface of a plating original sheet. As the pickling soln., a sulfuric acid soln. is desirable. Next, the pretreated steel sheet is electroplated with an acidic plating bath contg. H2SO4. The plating current density is not particularly limited, and generally, by 30 to 150 A/dm2 current density at which it is industrially produced for electrogalvanizing a steel sheet or by the higher current density, e.g. 200 A/dm2, the effect of dissolving unevenness and improving whiteness can be obtd. The applicable pH in the plating both is different in accordance with the anode system, but, in the case an insoluble anode is used, the pH in the plating bath is desirably controlled to 0.8 to 2.5.

摘要： PROBLEM TO BE SOLVED: To impart stable and low contact resistance and to improve cell characteristics by discontinuously forming nickel plated layers on one side of the surfaces of a low carbon steel sheet, then anodically electrolyzing the one side of the surfaces in an acidic solution in order to form many small pits at exposed steel parts and forming a nickel plated layer onto the both surfaces of the steel sheet. SOLUTION: Discontinuous nickel plated layers 1 having a mass of deposit of 0.05-0.50 g/m2 are formed on one side of the surfaces of an aluminum killed low carbon steel sheet 3, whose surface has been cleaned by dewaxing and removing iron oxides. The discontinuously nickel plated surface is anodically electrolyzed in an acidic solution having a pH of 2-5 at a bath temp. of about 30-60 deg.C and at a current density of about 10-60 A/dm2 for about 0.3-5 sec in order to solve only exposed steel parts 2 and form many small pits 4. Thereafter, both surfaces of the steel sheet 3 having many small pits on its one surface are subjected to nickel plating for forming nickel plated layer having a mass of deposit of 9-45 g/cm2. If necessary, the adherability is enhanced by forming a nickel-iron diffusion layer between nickel plated layer and the steel sheet by heating at 450-700 deg.C.
