Abstract:
An aluminum-scandium (Al—Sc) alloy film applied to vehicle lamps and a manufacturing method thereof are revealed. The Al—Sc alloy film contains a trace of scandium so that both temperature for grain refinement and temperature for recrystallization of the film are increased. This results in a fine and smooth surface of the Al—Sc alloy film and the Al—Sc alloy film has better optical reflectivity. Moreover, the Al—Sc alloy film has high recrystallization temperature and high adhesion strength. After high temperature annealing treatment, the Al—Sc alloy film still has higher corrosion resistance.

Abstract:
A hydrogen storage device includes a hydrogen storage can, at least one first partition, and at least one second partition. The hydrogen storage can defines a major axis. The at least one first partition is used to partition the space in the hydrogen storage can into at least one compartment. The at least one second partition includes a plurality of sub-compartments. The sub-compartments are arranged linearly in at least one row perpendicular to the major axis.
Abstract:
A continuous micro anode guided electroplating device and a method thereof are revealed. By real-time image monitoring and capillary action of the micro/nanoscale tube, a three-dimensional microstructure is deposited on a workpiece at the cathode. The deposit is growing smoothly under the real-time image monitoring. Moreover, the workpiece is not immersed in an electrolyte so that contaminations of the workpiece caused by electrolyte are reduced.
Abstract:
A method for making Mg(magnesium)-based intermetallic compound uses a thermal process during a melting process to produce largely the Mg-based intermetallic compound. The vapor pressure of Mg is high, thereby Mg is prone to be vaporized from a melt and a wrought solid alloy in the melting process of high temperature, for purifying the wrought Mg-based intermetallic compound. The method may simplify the process and devices for making the Mg-based intermetallic compound, and produce efficiently a larger of high purity Mg-based intermetallic compound.

Abstract:
The present invention provides a method for mass producing any metal alloy. After melting a metal mixture, a mixture of heating, soaking and/or cooling is processed to obtain the alloy even with a trace element added. The metal alloy made by the present invention thus has a high purity and a low cost.
