METHOD OF MEASURING DESTRUCTION RATE IN CORROSION MECHANICAL TESTS OF METALLIC MATERIALS Russian patent published in 1994 - IPC

FIELD: corrosion-mechanical tests. SUBSTANCE: method involves the steps of: placing a specimen of material to be tested in a corrosion medium, loading the specimen and subjecting it to electromagnetic field produced by a current loop disposed over the specimen, maintaining it for a predetermined time period, determining a change in inductance of the current loop, unloading the specimen and determining a change in inductance of the current loop and finally estimating a destruction rate from a parameter which is selected as the difference between inductance value of the current loop at the loaded specimen and unloaded one. EFFECT: enhanced reliability and accuracy, dominating destruction type determined. 1 dwg
