Profile: Teer Coatings Ltd. develops new fouling resistant coatings using PACVD and hybrid PVD-PACVD processes. We design and manufacture coating systems incorporating unbalanced magnetrons in the patented closed field arrangement. We also provide coating services, magnetrons, testing equipment & service, and technical support & service. The ST30 is a manual scratch tester that enables simple determination of the coating adhesion by measuring the resulting track using a metallographic microscope. The sample under test is secured on a tilted table which is driven against a diamond indenter, the slope of the table and the characteristics of the sample determine the loading rate.
