Abstract: A production method for an aluminum alloy coated steel sheet. The aluminum alloy coated steel sheet is improved in appearance, corrosion resistance and workability resulting from dipping a base steel sheet into an aluminum alloy coating bath with a Si content of 7 to 15 parts by weight, a Cr content of 0.5 to 1.5 parts by weight and a Mg content of 0.46 to 3.0 parts by weight. Because of excellent workability, peeling of a coating layer and cracks of a coating film are reduced upon press working, thereby corrosion resistance being improved even after working. As a result, car mufflers, heat resistant home electric appliances, etc. having improved corrosion resistance can be produced.

The aluminum alloy coated steel sheet is improved in appearance, corrosion resistance and workability resulting from dipping a base steel sheet into an aluminum alloy coating bath with a Si content of 5 to 15 parts by weight, a Cr content of 0.1 to 1.5 parts by weight and a Mg content of 0.01 to 3.0 parts by weight. Because of excellent workability, peeling of a coating layer and cracks of a coating film are reduced upon press working, thereby corrosion resistance being improved even after working.

Abstract: A method for manufacturing a gravure transfer-coated continuous metal plate, wound in the form of a coil, comprising: coating, over the metal plate, a primer coating material; curing the primer coating material to form a lower coating layer; thermally transferring a desired pattern from a gravure transfer sheet onto the lower coating layer, thereby forming a transfer coating; coating, over the transfer coating, an upper coating material of thermosetting fluorine resin, thermosetting polyester resin, or UV-thermosetting polyurethane-acryl-based resin; and curing the upper coating material to form an upper coating layer. The primer coating material consists essentially of: 20-40% polyester resin having a number average molecular weight of 5,000-20,000 and a glass transition temperature of 10-50° C., 4-15% melamine resin, 1-10% urethane resin, 0.3-3% isocyanate, 15-35% pigment 30-50% hydrocarbon/ester-based mixed solvent, and 1.5-3% additives.

Abstract: Disclosed is a technique for manufacturing a Ni—Fe alloy thin foil using a single-step electrodeposition-based plating process without requiring processes such as melting, casting, forging, and rolling. A manufacturing apparatus is provided which includes an electrolyzer adapted to receive an electrolyte containing, as a major component thereof, a solution of nickel and iron compounds, a cathode partially dipped in the electrolyte and arranged in such a fashion that it is rotatable, an anode completely dipped in the electrolyte and arranged in such a fashion that it faces the cathode while being spaced apart from the cathode by a desired distance, and a current supply device adapted to generate a flow of current between the cathode and the anode, whereby a Ni—Fe alloy thin film is electrodeposited to a desired thickness over a surface of the cathode facing the anode, and then peeled off from the surface of the cathode, so that a continuous Ni—Fe alloy thin foil is manufactured.
