PROCESS OF DETERMINATION OF ADHESION OF GASOTHERMIC COAT Russian patent published in 1997 - IPC

FIELD: measurement technology. SUBSTANCE: sample is manufactured in the form of backing and examined coat deposited on it. Sample is bonded to countersample. After this two through cuts are made in backing parallel to each other and perpendicular to boundary of separation between backing and coat. Area S₁ of contact of backing and coat should not exceed its value found from relation 2 , where 3 σ₂ is adhesive strength of cement; 4 S₂ area of contact of coat and countersample and 5 δ₁ is predicted strength of adhesion of coat to backing. Uniform separation of coat from backing is performed and parameter by which adhesion of gas-thermic coat is evaluated is found. EFFECT: improved accuracy of determination of adhesion. 1 dwg , 1 tbl
