METHOD OF DETERMINATION OF ADHESION STRENGTH Russian patent published in 1994 - IPC

FIELD: investigation of physical-chemical and production processes. SUBSTANCE: operation of adhesiometer is based on breakage of specimen representing a coating in the form of a drop placed in the hole of a plate-cutter during whose movement on the surface of a fixed backing the hole generatrix breaks the sample due to the shearing force. The value of breaking load related to the contact area is the comparative characteristic of strength. At the same time the kind and nature of breakage are determined at investigation of formed surfaces. The method does not need production of standardized specimens, it is convenient at estimation of durability of the contact area. Adhesiometer dimensions - 80x100x300 mm, mass - 5 kg, time required to test a single specimen - 2 to 3 min. EFFECT: enhanced truth of determination of adhesion strength of materials. 1 dwg
