Scratch Tester

Description

Description

The Scratch Tester is a versatile instrument capable of quantifying scratch resistance, critical load, adhesion and bond strength for a wide range of surfaces. The tester evaluates scratch resistance of a sliding surface in relative motion (X movement) to a stylus. The stylus is pressed against the moving surface with controlled force which is normal to the surface. Tangential force at the contact is measured. The ratio of tangential and normal forces is merely the co-efficient of friction till the threshold of surface damage. Energy required to damage the surface contributes an additional component to the tangential force, which increase this ratio. Force ratio is not the only sign of damage - acoustic emission level also increases corroborating the occurrence of surface damage. Image of the entire scratch may be captured and the view at any given load can be seen to study nature of failure.
