Creation of Highly Oleophilic Surfaces by Wettability Control

―Plasma Surface Modification to Resin Sliding Materials―

Abstract

On the surface of resin, additives such as oil agent for metals cannot be used, and the affinity with oil is poor. It is considered to improve the wettability of oil and avoid the direct contact with solids is effective to reduce the friction of resin under oil lubrication. This article introduces the plasma surface modification as a method to improve the oil wettability of resin surface. Then, the practical example that improved tribological characteristics by the plasma modification is introduced with explanation of mechanisms.
