Scratch Tester easySCRATCH

Product catalog summary

Overview: The easySCRATCH is a cost-effective scratch tester designed for adhesion testing between coatings and base materials. It is suitable for quality assurance and coating development, adhering to standards DIN EN ISO 20502 and ASTM C1624.

Specifications:

Test Load Range: 10 - 120 N in steps of 10 N (additional steps available on request).
Scratch Speed: 5 - 20 mm/min.
Scratch Length: 2 - 40 mm.
Max. Travelling Path: 90 mm.
Max. Sample Height: 40 mm.
Clamping Range for Flat Samples: 36 mm.
Dimensions (without weights): 460/295/295 mm (h/w/d).
Power Supply: 85 – 264 VAC, 47 – 63 Hz.
Weight: Device 13.5 kg, weights approx. 11 kg.

Features:

Quick and easy operation with user-friendly interface.
Diamond stylus (Rockwell-C-indenter) for creating scratch marks.
Motor-driven sample movement with adjustable speed and scratch length.
Easy exchange of test weights and indenter for inspection or replacement.

Applications: Suitable for hard-coated materials (PVD, CVD) with coating thicknesses up to 30 µm. Example application includes W-DLC coating.

Procedure: The device uses a diamond stylus to apply a load across the coating. The resulting damage, such as cracks or chipping, is assessed under a microscope. For production tests, a constant load is used to determine a PASS or FAIL outcome, simplifying the assessment process.

Options:

Indenter with DAkkS or ASTM certificate.
V-Block for cylindrical samples (ø 5 - 30 mm, length 90 mm).
Microscopes for scratch evaluation.
Bidirectional multipass scratch capability.

cost-effective method for adhesion testing The scratch tester easyScratch is used to determine the adhesion between the coating and the base material according to DIN EN ISO 20502 and ASTM C1624. Under load, a diamond stylus is drawn across the to be tested coating system. The coating damage is assessed under a microscope. Several coating damage, such as cracks, chipping and spalling can occur. For tests during production, it is generally sufficient to test with a constant load, at which no coating damages may occur. Like that the sample can directly be rated, PASS or FAIL. This reduces the effort...
