摘要： PROBLEM TO BE SOLVED: To provide a hot-dip Zn-Al-Mg-Si-plated steel sheet which has superior surface appearance with few black spots, and to provide a manufacturing method therefor.
SOLUTION: The method for manufacturing the hot-dip Zn-Al-Mg-Si-plated steel sheet comprises the steps of: reducing a base steel sheet while heating it; cooling it; hot-dipping it in a bath including 2.8% or more Mg, 10.5% or more Al, 0.01-0.5% Si and the balance Zn with unavoidable components; adjusting a coating mass of the plated layer on the steel sheet appearing from a hot dipping pot, with a gas wiping technique; and cooling and solidifying the plated layer in a molten state at a cooling rate of 10°C/s or higher in a temperature range of 340±10°C and at a cooling rate of 7°C/s or lower in a temperature range of 330 to 310°C. Thus obtained steel sheet has a Zn-alloy-plated layer of which the X-ray intensity ratio of Mg
2 Zn

摘要： PROBLEM TO BE SOLVED: To lessen the consumption of two sheets of insoluble anodes and to prolong the service life of these anodes by changing the amt. of the electrode active substances according to the potential difference to be impressed on the electrodes at the time of applying the electroplating on both surfaces of a steel sheet in different amts. by using two sheets of the insoluble anodes. SOLUTION: At the time of allowing the steel sheet to travel between two sheets of the insoluble anodes in the plating liquid and applying the electroplating of the different amts. on both surfaces thereof, the width of the insoluble anodes is set larger than the width of the steel sheet to be plated and both surfaces of the steel sheet are plated by giving a difference in the potential of the anodes by a difference in the plating amts. The insoluble anodes are formed by coating the surfaces of titanium substrates with iridium oxide or a compound oxide of iridium-tantalum, iridium- titanium, etc., as the electrode active substances. The coating material, of the electrode active substance on the anode surface where cathode polarization is induced by the difference in the potential between the two anodes is set at 60 g/m and the coating amt. of the electrode active substance of the anode where the cathode polarization does not arise is set at 15 to 60 g/m . As a result, the consumption of the electrode active substance by the cathode polarization of the anodes is decreased.

摘要： PURPOSE:To improve corrosion resistance in high-current-density electrolysis by providing the metallic Ir layer and dense IrO2 layer with the relative density specified on an electrode substrate as an intermediate layer and then furnishing a conductive layer of IrO2 by a coating and baking means. CONSTITUTION:An electrode substrate 1 is made of a valve metal 2 alone or obtained by providing a valve metal layer on the metallic substrate 1. A metallic Ir layer 8 having >=90% relative density as the first layer and a dense IrO2 layer 7 having >=90% relative density as the second layer are formed on the substrate 1. A conductive layer consisting essentially of IrO2 is formed through the first and second intermediate layers 8 and 7 as the outermost surface layer by a coating and baking means. The thickness of the first and second layers 8 and 7 is preferably controlled to about 0.01-5mum. Consequently, the pores and cracks 5 are practically eliminated, the corrosion of the substrate 1 and the formation of an insulating oxide coating film are prevented because a plating soln. is less apt to reach the substrate 1.
