Abstract

In this study, the tribological characteristics of silver films that were deposited on a glass substrate by electroless plating were investigated. The electroless-plating method has many notable advantages. It is easy and economical to obtain solid films using this coating process, and it can be applied to both nonconducting and conducting substrates. In this study, silver was selected as the electroless-plating material because it is one of the most common materials used as a solid lubricant. The mechanical properties of silver electroless-plated specimens were investigated for various coating conditions. The thickness of the coating could be controlled by varying the electroless-plating time. The properties of the coatings were investigated using AFM, SEM, and a tribotester.

본 연구에서는 무전해 도금 코팅방법을 이용하여 생성한 Ag 박막의 기계적 특성을 고찰하였다. 이 코팅방법은 화학적 반응을 통해 금속박막을 기판 위에 형성할 수 있는 공정으로써 비교적 간단하고 경제적이며 전기도금과 비교했을 때 도체뿐만 아니라 부도체에도 적용할 수 있다는 유리한 장점이 있다. 따라서 반도체에서부터 기계부품에 이르기까지 산업전반에 걸쳐 다양하게 적용되고 있는 코팅방법이다. 본 연구에서는 무전해 도금 공정의 변수에 따라 형성되는 Ag 박막의 기계적 특성을 파악하는데 중점을 두었다. 특히, 무전해 도금방법을 이용해 제작한 코팅 시편에 대해 도금시간에 따른 거칠기 및 두께에 대한 분석을 실시하였으며 AFM, SEM, Tribotester 와 같은 장비를 이용하여 트라이볼로지적 특성을 규명하였다.
