전착도장 마모 수명과 상대재의 기계적 특성 사이의 관계 연구

Abstract

This article investigates the effect of mechanical properties of a counterpart on the wear lifetime of an electro-deposited coating. Reciprocal sliding tests using ball-on-flat contact configuration were conducted under the condition similar to those found in an automotive seat slide rail. The kinetic friction coefficient between the coating and the counterpart was measured during the test. Wear lifetime of the coating was defined as the number of cycles to a critical friction coefficient. It was identified that wear lifetime of the coating varies according to counterpart material. It was found that there is the linear relation between the wear lifetime and the ratio of hardness to elastic modulus of a counterpart. Obtained results could be used for predicting the wear lifetime of an electro-deposited coating.
