摘要

PROBLEM TO BE SOLVED: To provide a design method for the rust preventive structure and rust preventive design of a mobile body by carrying out a quantitative method for measuring corrosive environment on the mobile body whose environment changes sharply.;SOLUTION: At least one corrosion sensor is installed at one or more parts of the mobile body at least a part of which is composed of a metal material, wherein the corrosion sensor has two kinds of metal electrodes different in component and/or composition, one kind of which is a metal material to be selected for a component of a mobile body material, while the other kind is the same metal different from the one kind and metal to be noble in an electrochemical rank to the one kind, and the corrosion sensor is arranged so that a clearance between a pair of electrodes is 0.1-5 mm across an insulator. An electric current or potential difference between the electrodes caused by electric short circuit of the electrodes in the corrosive environment is continuously or intermittently measured including a moving time.;COPYRIGHT: (C)2009,JPO&INPIT
