CSM Instruments Announce Free Scratch Testing Webinar

CSM Instruments has announced a free webinar entitled "Scratch Testing, a useful technique for coating adhesion and scratch resistance".

It will take place on June 6th, 2012, at 16:00 Central European Time (15:00 GMT / 11:00 EST).

About CSM Instruments Scratch Testers

CSM Instruments Scratch Testers are ideal instruments for characterizing the surface mechanical properties of thin films and coatings, e.g. adhesion, fracture and deformation. They can be used for all kinds of industrial coatings from the plasma processed layers used in semiconductor and optical technology to the decorative and protective coatings used for consumer goods and automobile parts.

The scratch tester's ability to characterize the film - substrate system and to quantify parameters such as friction force and adhesive strength, using a variety of complementary methods, makes it an invaluable tool for research, development and quality control.

The technique involves generating a controlled scratch with a diamond tip on the sample under test. The tip is drawn across the coated surface under constant, incremental or progressive load.

At a certain critical load the coating will start to fail. The critical loads are very precisely detected by means of the friction coefficient, the penetration depth, the acoustic emission sensor together with observations from a built-in optical microscope.

The critical load data is used to quantify the adhesive properties of different film - substrate combinations by using different sensors (acoustic emission, penetration depth, friction force) and video microscope observations.

There will be a Live Q & A session following the webinar presentation. After the live webinar, the recorded presentation will be made available.
