TL;DR: A surface-coated steel sheet having improved corrosion resistance and suitable for use as automobile inner and outer panels comprises a steel sheet with on at least one surface thereof a composite coating which comprises the following layers (a) to (d) from the bottom to the top of the coating: (b) a first zinc alloy plating layer with a coating weight of 10-100 g/m2 which contains at least 1 of Ni and Co in an amount satisfying the following inequality: 0.05≦(5×Co)+Ni≦10 (in weight percent),

TL;DR: A surface-coated aluminum material having improved corrosion resistance comprises a base aluminum or aluminum alloy material having on at least one surface thereof an aluminum-manganese alloy coating with a coating weight of 0.1 - 50 g/m² which may be further coated with an oxide film or chemical conversion coating as mentioned in this paper.

TL;DR: In this article, a method and apparatus of continuous electroplating of a strip with an alloy by passing the strip through a plating bath of the immersion type in both down-pass and up-pass with an anode being positioned in each pass so as to face at least one side of the strip are disclosed.

TL;DR: A multilayer plated aluminum sheet suitable for use in automobile body panels comprises a base aluminum sheet made of aluminum or an aluminum alloy and has a first layer of zinc or a zinc alloy formed by displacement plating on the surface of the aluminum sheet and one or more layers of electroplated coating formed on the first layer by electroplating in an acidic bath as discussed by the authors.

TL;DR: In this article, a material for producing far-infrared radiation is disclosed, which consists of a substrate and an Al-Mn alloy-derived oxide surface layer on the substrate, the oxide surface surface layer being porous with an average pore diameter of 0.01-2.0 micrometers and a porosity of 103 -1012 pores/cm2, the weight ratio of Mn/Al of the oxide layer being 0.001-2
