Abstract
As a novel approach for analyzing the particles generated in sliding wear, we have coupled a modified Taber abraser (TA) test with a liquid particle count analysis (LPC) of the generated particles. The particle generation function for plastics metallized by a magnetron sputter deposition method was determined. The counterbody was an aluminium slider. By combining these two methods, a differential analysis of the size of particles as a function of sliding distance can be obtained, thus making it possible to qualify metal coatings on plastics for use in particle sensitive environments. The experimental set-up is described, and sample data are presented. SEM EDX was additionally used to determine the morphology and origin of the particles. Materials studied: Titanium nitride and titanium carbide coatings on PA and PBT.
