    摘要: In order to produce a coating on a substrate, the substrate is placed adjacent to a target. Material is cold ablated off the target by focusing a number of consecutive laser pulses on the target, thus producing a number of consecutive plasma fronts that move at least partly to the direction of said substrate. The time difference between said consecutive laser pulses is so short that constituents resulting from a number of consecutive plasma fronts form a nucleus on a surface of the substrate where a mean energy of said constituents allows the spontaneous formation of a crystalline structure.

    摘要: The present invention features a method for preparing a PtCo nanocube catalyst, the method comprising dissolving a platinum (Pt) precursor, a cobalt (Co) precursor, a surface stabilizer and a reducing agent in a solvent to prepare a solution; heating the solution under an inert gas atmosphere; maintaining the temperature of the solution to obtain PtCo alloy nanocubes; adsorbing the PtCo alloy nanocubes on a carbon support to obtain a catalyst; and removing the surface stabilizer from the catalyst. The disclosed method for preparing a PtCo nanocube catalyst enables preparation of nanocubes with uniform size and cubic shape through a simple process and application for development of high-efficiency fuel cells by preventing change in shape, surface area and composition caused by agglomeration of the nanocubes.

    摘要: An object of the present invention is to provide a material for a precious metal tip of a spark plug, which has more excellent durability, particularly oxidation wear resistance than a conventional one. The precious metal alloy for the spark plug according to the present invention contains 0.2 to 6.0 wt. % Cr as an essential component, further at least any one of Fe or Ni, and the balance being Ir. Here, the amount of Fe and Ni to be added is preferably 2.0 to 12.0 wt. % in total. According to the present invention, the surface may be oxidized to form an oxide layer made from a Cr—Fe oxide, a Cr—Ni oxide or a Cr—Fe—Ni oxide. The oxide layer is formed by a diffusion treatment by heating the precious metal alloy at 300 to 900° C. in an oxidative atmosphere, and preferably has a thickness of 5 to 100 μm.
