apparatus and method for non-destructive estimation and location of corrosive phenomena of metal armor for a structure, in particular, the armor of steel of a stream of limeostrich.

摘要

the apparatus comprises essentially a current generating unit (2) and a unit for the detection of thermal effects (3).the method is to pass an electric current in metal suit (9, 23, 14) of a structure (10, 22, 24), which acts as an electric resistance.and to take the thermal gradient between the surface area heated structure (10, 22, 24) which indicates a reduction of section of armor for corrosion.
