Abstract
Experimental studies on wear performance and wear mechanisms of fluoropolymer based composite, non-stick coatings on aluminum substrates were carried out by using particular wear testing methods, i.e. the “mechanical tiger paw (MTP) Test” and the “Nord Test”. Both are supposed to simulate household abrasive operating conditions in a laboratory environment. It was found that the wear process involved in the MTP Test was an accelerated one, but that in the Nord Test was decelerated due to a transition from severe three-body abrasion to milder two-body sliding wear. In addition, both effects of the microstructure of the coatings and of the surface treatment of the substrates were discussed.
