摘要： PROBLEM TO BE SOLVED: To provide a surface-treated steel sheet which balances plane corrosion resistance with end corrosion resistance. SOLUTION: The Al-Zn plated steel sheet superior in corrosion resistance has an Al-Zn plated layer comprising, by mass%, 10% or more Zn, 0.5-15% Si, 0.05% or more Cr, and the balance Al with unavoidable impurities, on the surface of a steel containing 3% or more Cr. The steel can contain Mo, Cu, Mn, and Ni, and the plated layer Mg, Sn, Ca, and a misch metal, as needed. The use of the Cr-containing steel as a base metal gives the Al-Zn plated steel sheet corrosion resistance on both the plane and the end, because Cr in the base steel diffuses into the plated layer.

摘要： PROBLEM TO BE SOLVED: To impart stable lubricity at the time of working, such as press forming, to a steel sheet and to prevent the occurrence of a forming defect and crack by distributing colloidal silica particles of a specified particle size to the surfaces of the steel sheet. SOLUTION: The colloidal silica powder having the primary crystal grain size of >=20mm is adhered at 0.05 to 1.0g/m by dry weight on the surfaces of the galvannealed steel sheet. The adhesion treatment is executed by coating the steel sheet with a soln. contg. the colloidal silica particles by a roll coater system, wringer roll system after spraying or immersing or air knife system, spraying system, etc. The reason for limiting the coating weight of the colloidal silica distributed in the steel sheet surfaces lies in that if the coating weight is smaller than 0.05g/m , the effect of improving the lubricity is not exhibited and that if the coating exceeds 1.0g/m , an increase of a production cost may be resulted and may lead to a change of the steel sheet surfaces to white and the occurrence of an appearance defect.

摘要： PROBLEM TO BE SOLVED: To impart excellent lubricity and degreasing properties to a steel sheet and to prevent the generation of defects in molding at the time of molding by pressing or the like and cracking by forming a chromate treated layer contg. colloidal silica particles on the surface of a steel sheet. SOLUTION: The surface of a galvannealed steel sheet is coated with a chromate treating soln. contg. colloidal silica particles having >=20nm primary particle size by a roll coater system, a wringer roll system after spraying or immersion, an air knife system or an atomizing system, and drying is executed to form a chromate layer. The coating weight of colloidal silica at this time is regulated to 0.05 to 1.0g/m by dry weight. Furthermore, the coating weight of the chromate layer is not particularly regulated, but, it is preferably regulated to the range of 5 to 40mg/m . The colloidal silica particles roll into the space between the steel sheet and the surface of a die, by which a coagulating phenomenon caused by the metal-metal contact between the surface of the die and the surface of the galvannealed steel sheet is suppressed to improve its lubricity.
