Scratch Testing System Analyzes Coating Adhesion

The Fischerscope ST200 from Paul N. Gardner is a progressive-load scratch tester designed to analyze the adhesion and cohesion strength of coatings according to ASTM C1624, ISO 20502 and DIN EN 1071-3. Typical fields of application include hard material coatings; automotive engine and drive train components; electroplated coatings; characterization of hard anodic coatings; materials used specifically in medical technology applications; electronic components, connectors and bond wires; and plasma-applied coating systems.

Features include constant-load, progressive-load and incremental-load measurement modes; optical microscopy, friction-force acoustic-emission analyzing methods; a motor-driven XY stage and Z axis; the ability to measure curved surfaces with motion feedback control; an automatic image scan of the whole scratch; diamond indenters of various geometries; optical filters for contrast improvement; integrated electronics; two microscope objectives; and easy creation of test reports.
