Automated Scratch Testing System for Analyzing the Adhesion and Cohesion Strength of Coatings

ASTM C1624, ISO 20502, and DIN EN 1071-3

Equotip


The FISCHERSCOPE® ST200 is a progressive load scratch tester for analyzing the adhesion and cohesion strength of coatings according to ASTM C1624, ISO 20502, and DIN EN 1071-3. The instrument is perfectly suitable for measurement in development, quality assurance, incoming inspection and process control.


Typical fields of application:

  • Hard material coatings (PVD, CVD)
  • Automotive engine and drive train components
  • Electroplated coatings (decorative, functional)
  • Characterization of hard anodic coatings
  • Materials used specifically in medical technology applications
  • Electronic components, connectors, bond wires, etc.
  • Plasma-applied coating systems

Benefits of Progressive Load Scratch Testing

top
  • Fundamental Mechanical Properties ← Nanoindentation - Scratch → Real World Conditions
  • Quantitative test- Failures defined by loads in Newtons or Millinewtons
  • Check the adhesion between thin coatings and the substrate
  • Characterize resistance of the coating to cracking, chipping and spallation
  • Simulate real world failures under controlled lab conditions
  • Measure according to ASTM C1624, ISO 20502 and DIN EN 1071-3
