RC adhesion test

ADHE-COAT TESTER
Instrument for adhesion test of PVD coatings

In accord to standard VDI 3198

TEST DADHESION RC 1


Manufacturers and users of hard coatings are often confronted with the problem of measuring adhesion of PVD coatings.

TRIBOtechnic has created a new and innovative instrument called ADHE-COAT TESTER fully equipped with all items needed for fast and convenient adhesion testing.


EASY AND FAST TO USE:
Indentation and observation

ECONOMICAL TO USE:
Low consumption of diamond tip:
10 times less than a scratch tester.     

 
Applications :
The method is compatible with the following coatings:
- PVD coatings
- DLC coatings

Procedure :
After a conventional hardness test according to DIN 50103, made by a Rockwell C indenter, user can visually evaluate the cracked perimeter. This test must be done on a sample or tool in speed steel at least 54 HRC, coated with layer maximum 5 µm thickness.


Examples of determination of adhesion of PVD coating on steel:

Good  adhesion                             Adhesion non acceptable
