Abstract

A Vicker M55 inverted microscope (Vickers Instrument, U.K.) with a stage upward at the top is refitted for normal indentation and scratch indentation tests of epoxy coating debonding induced by indenters of tungsten carbide (WC) spheres and cones on the soda-lime glass substrates. A special designed apparatus assembled on the microscope stage can load the indenter quantitatively onto the coating and the amounts entering into the coating of indenter can be read out by an alignment microscope. The model system of the coating/substrate combination between the indenter and the objectives of Vicker microscope can be slide by handle and motor with velocity of 0.8 mm/min. Lots of experiments are done with satisfactory results by the use of the refitted microscope.
