AST210

Multi-Function Adhesion Scratch Test System

General Information
In the ultra-precision industry of metallic materials and semi-conductors, surface treatment technology is an essential component of protecting and strengthening the surface layer. The performance of thin film coating is largely influenced by the properties of the thin film layer and its adhesiveness to the base material.
AST210 system, using sound wave technology, measures the coating layer’s adhesiveness to the base metal as well as the surface frictional force of the thin film.
