METHOD OF ESTIMATION OF COALESCENCE STRENGTH OF CLAD LAYER WITH PARENT MATERIAL Russian patent published in 1995 - IPC

FIELD: mechanical tests of materials. SUBSTANCE: blind hole is made in parent material on side of surface being cladded and insert member is placed in it; part of surface of insert member is cladded together with surface of parent material, after which axial slot is made in clad layer which separated breaking-off area which is at definite ratio with area of cut of clad layer. Standard tensile-testing machines are not used. EFFECT: method makes it possible to estimate definitively the quality of coalescence of clad layer with parent material by the following principle: satisfactory or unsatisfactory; there is no need to cut cards from blanket or article which makes it possible to restore serviceability of article or blank after test. 2 dwg
