| Summary: | 碩士 === 國立臺灣科技大學 === 機械工程系 === 96 === The CrN coating had high hardness, low scratch coefficient and
good antibacterial properties. Therefore, the CrN coatings have been used
widely in the molding industrial. The addition of Cu into the CrN thin
film will further improve the mechanical properties of coating effectively.
In this work, the Cr-Cu-N nanocomposite thin films with Cu content
ranging from 1.6 to 24.1 at.% have been deposited by a bipolar
asymmetric pulsed DC reactive magnetron sputtering system. The
mechanical properties, corrosion behavior and antibacterial test of
Cr-Cu-N thin films with different Cu content were investigated. A
combination of high hardness for the Cr-Cu-N coating containing 15.2
at.%. It was observed that the antibacterial rate increased with the
increasing Cu content in the coating, which was due to sufficient amount
of Cu ions released. The corrosion resistance of Cr-Cu-N thin films is
decreased as the Cu content increased in the NaCl aqueous solution. The
copper oxide is produced on the surface of thin film after annealed. The
hardness is also effected with different Cu contain and annealing
temperature after annealed
