    • The present invention relates to a method for manufacturing a novel hydrogen sensor, the method comprising the steps of: forming a thin film on an elastic substrate using a transition metal or an alloy thereof; and applying tension to the elastic substrate to form a plurality of nanogaps in the thin film formed on the elastic substrate. When the tension is applied, the thin film is elongated in the direction of the tension and is compressed in a direction perpendicular to the direction of the tension, and when the tension is not applied, the thin film contracts in the direction in which the tension was applied, and expands in the direction perpendicular to the direction in which the tension was applied. In this way, nanogaps are formed in the thin film.

    • A process for manufacturing an Alnico system permanent magnet is disclosed in which the alloy powder of the Alnico system having the proper composition is manufactured through a rapid solidification process, so that the crushability and the formability should be superior, the sintered density should be high, and the magnetic properties should be excellent, as well as cheap in its manufacturing cost and simple in its manufacturing process. An alloy of Alnico system is subjected to a rapid solidification with a spinning solidifier wheel speed of 6 - 40 m/sec, thereby manufacturing a micro-crystalline rapidly solidified powder. The powder is ground into a finer powder, and then a press-forming is carried out. Then a sintering is carried out at a temperature of 100 - 1350 DEG C for 0.5 - 4 hours. Then based on a single heat treatment, an external magnetizing force of 1 - 15 kOe is applied in a temperature range of 600 - 1000 DEG C, thereby carrying out a heat treatment under a magnetizing force. Thereafter, an aging heat treatment is carried out at a temperature of 500 - 700 DEG C for 1 - 10 hours, thereby magnetizing the formed body.
    • 公开了一种制造Alnico系永磁体的方法,其中通过快速固化方法制造具有适当成分的Alnico系统的合金粉末,从而使粉碎性和成形性应优于烧结密度, 磁性能优异,制造成本低,制造工艺简单。 AlNico系统的合金以6〜40m /秒的纺丝凝固轮速度进行快速凝固,由此制造微晶快速凝固的粉末。 将粉末研磨成更细的粉末,然后进行压制成型。 然后在100〜1350℃的温度下进行烧结0.5〜4小时。 然后基于单次热处理,在600-1000℃的温度范围内施加1〜15kOe的外部磁化力,从而在磁化力下进行热处理。 然后,在500-700℃的温度下进行1〜10小时的老化热处理,由此磁化成形体。
