FISCHERSCOPE® ST200

Product catalog summary

Overview: The FISCHERSCOPE® ST 200 is an automated scratch tester designed to evaluate the adhesion properties of coatings, particularly in surface technology applications. It is crucial for assessing the reliability and service life of coatings used on cutting tools and other components.

Principle of Operation: The scratch test involves a diamond-tip indenter drawn across a sample at a constant speed. The test simulates real-life stresses on coatings, with results dependent on indenter shape, scratch length, and test force. The critical load (LC) is the force at which the coating fails, indicated by cracks and chipping.

Testing Capabilities: The ST 200 can handle a wide range of test loads from 0.5 to 200 N, making it suitable for hard coatings and thicker paint layers. It is applicable in various fields, including cutting tools, engine parts, dental prostheses, artificial joints, decorative coatings, and car paint.

Features: The device includes a powerful microscope for automatic detection and evaluation of scratches, measuring tangential force, penetration depth, and acoustic emissions. The WinSCU® software facilitates real-time evaluation with critical loads defined quickly. The system is user-friendly, requiring minimal sample preparation, and connects easily to computers via USB. It supports automated measurements with a programmable stage and can analyze parts up to 8 cm tall.

Technical Specifications: The ST 200 offers test forces between 0.5 and 200 N, with three measurement modes (constant, linear increase, incremental increase). It comes standard with a Rockwell indenter (radius 200 µm) and complies with ISO 20502, DIN EN 1071-3, and ASTM C1624 standards. Special holders allow for testing complex-shaped samples.

Global Reach: Helmut Fischer GmbH provides global sales, application support, and service, with headquarters in Sindelfingen, Germany.

In the area of surface technology, coatings have long been high-tech products. Especially with coatings meant to protect such parts as cutting tools from wear, how well the coating adheres to the substrate is decisive for its reliability and service life. The scratch test is an established method for simulating in a laboratory setting the stresses that a coating undergoes in everyday use. Particularly suitable for R & D, quality assurance and incoming goods inspection is the FISCHERSCOPE® ST 200 - Fischer's automated scratch test system. It tests the adhesive and cohesive strength of thin coatings...

Convenient operation and evaluation The FISCHERSCOPE ST 200 has a powerful microscope for automatically detecting and precisely evaluating the course of the scratch. In addition, the tangential force, the penetration depth and the acoustic emissions are measured. The intuitive WinSCU® software combines all three parameters in just one evaluation in real time: the critical loads are thus defined in just a few mouse clicks. The FISCHERSCOPE ST 200 is designed for easy operation. And with just one USB cable, you can easily connect the scratch tester to any computer. The programmable measuring stage...
