DLC 코팅 마모면에 대한 원자력 현미경을 이용한 고찰
An investigation of worn DLC coatings using atomic force microscopy
초록
Tribofilms formed on worn surface protect the DLC coating surface and decrease the friction coefficient. However it is very difficult to evaluate their micromechanical properties due to their small thickness, inhomogeneity and discontinuity. The phase contrast images in tapping mode atomic force microscopy allow an estimation of inhomogeneity in micromechanical properties of the sample surface. The purpose of this investigation is to demonstrate how the phase contrast images contribute to the characterization of thin tribofilms.
