티타늄 박막을 증착시킨 알루미늄의 마모 특성에 관한 연구

Abstract

Aluminium alloys have excellent strength and fatigue characteristics and are widely used as substitutes for steel in the aviation and ship automobile industries. Parts of the Al 7075 alloy used in the industry are subject to constant friction, damage and destruction at the contact surface between component and component. As a result, the need for functional materials suitable for specific applications is increasing. Surface coating technology is widely used to increase abrasion resistance and protect the material inside from the external environment. In this study, the abrasion resistance characteristics are considered when the DC magnetron sputtering power of the thin film is applied and the pressure is changed during the actual thin film deposition after argon is injected and plasma is formed. After that, the thickness of the thin film for each condition was measured, and the hardness was measured when the titanium thin film was formed. Then, the wear track was checked through the scanning electron microscope and the amount of wear was calculated. We have confirmed that abrasion resistance of Ti thin film decreases as deposition time increases and decreases when power is increased.
