  • 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.

  • Publication number: 20210047721
    Abstract: The present invention relates to: Ti alloy coating-film having excellent adherence with a base material, low friction resistance, and excellent hardness and elastic modulus characteristics; a method for manufacturing the coating-film, and a compressor comprising a component to which the coating-film is applied. According to the present invention, provided is the coating-film having: an amorphous matrix comprising Ti as a main component; and a nano composite microstructure including nanocrystals comprising TiN components dispersed in the matrix, thereby having an effect of increasing the ratio of H/E (hardness/elastic modulus) so as to enable the durability of the coating-film to improve.
