  • Patent number: 11408060
    Abstract: The present invention relates to an amorphous alloy having low frictional resistance and capable of improving abrasion resistance, a target made of the amorphous alloy, and a compressor comprising a layer of the amorphous alloy as a coating layer. According to the present invention, it is possible to secure high hardness and a low elastic modulus of the coating layer by controlling a microstructure having an amorphous phase as a primary phase by using Ti-based three-component to five-component amorphous alloys. As a result, it is possible to prevent the coating layer from being peeled off from a matrix or destroyed, and thus it is possible to achieve the effect of improving reliability or durability of a mechanical apparatus such as a compressor.

  • Patent number: 9725560
    Abstract: The present invention relates to a catalyst for reductive amination-reaction, and uses thereof. The catalyst according to the present invention can show a high amine conversion rate because it can maintain catalytic activity even in the presence of moisture particularly while basically maintaining the balance of dehydrogenation and hydrogenation reactions. Accordingly, the catalyst can be usefully used for preparing a polyetheramine compound through a reductive amination-reaction not only in a continuous preparation process but also in a batch preparation process, irrespective of the existence of moisture.

  • Patent number: 9133353
    Abstract: In a method for preparing a polyimide resin by reacting diamine and dianhydride, the polyimide resin is polymerized under the presence of a solvent having a boiling point ranging from 130° C. to 180° C. so as to be curable at a low temperature ranging from 150° C. to 250° C. Because the polyimide is curable even at a low temperature, when the polyimide resin is used as an electronic material, damage to equipment due to an otherwise high temperature process can be minimized, and in addition, the polyimide resin can be extensively used as an electronic material such as for a plastic substrate, or the like.
