Abstract
PURPOSE: To inspect faults on insulating coating layer on a container, conductive solution containing minor amount of metal ions is filled in the container, and solution and container are made anode and cathode respectively. Then, voltage is applied to electrodeposit metal ions on deffects of coating layer, while measuring leakage current.
CONSTITUTION: Electrode plates 3 are insulatively located as anode in water chamber 1, and the water chamber 1 and pipe body 2 are made as cathode. An d.c. power supply 4 and ammeter A are located between the electrodes to apply voltage, and conductive solution 7 from tank 6 is circulated through the water chamber 1 and the pipe body 2. The conductive solution 7 is an aqueous 3% NaCl solution added with 0.4% AlCl3. After stopping circulation pump and recovering the conductive solution 7 into the tank 6, the internal of the water chamber 1 and the pipe body 2 is observed. Should defect be present on the insulating coating layer, such defect is clearly indicated by the deposition of granular zinc.
