Are intended for determination of adhesion by a method of cuts (parallel, trellised or "X"-shaped).
Description
Adgezimetra are executed in the form of the template with rated cuts made of a flat plate of stainless steel.
Use
Adgezimetr keeps within on an ispytuyemy surface, the covering is cut by a knife razor to a substrate, the place of a section is cleared by a brush or by means of a sticky tape adhesive tape (depending on a technique), adhesion is estimated visually on mark system.
Cuts carry out parallel or trellised through equal distances (1 mm, 2 mm or 3 mm - depending on layer thickness).
Basic principles of the choice and applicability
Requirements of the specifications and technical documentation.
At thickness of covering more than 200 microns, and also at determination of adhesion of hard coatings when use of adgezimetr of trellised and parallel cuts is impossible, it is used adgezimetr a H-shaped cut (Constant-AH).
