Document Type and Number:
WIPO Patent Application WO/2019/147022
Kind Code:
A1
Abstract:
The present invention relates to: a 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 or comprising Si on the basis of Ti as the 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.
