CORROSIONPROOF MAGNESIUM ALLOY MEMBER, CORROSIONPROOFING TREATMENT METHOD FOR MAGNESIUM ALLOY MEMBER, AND CORROSIONPROOFING METHOD FOR MAGNESIUM ALLOY MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a corrosionroof magnesium alloy member of which any desired part is easily made corrosionproof.;SOLUTION: The corrosionproof magnesium alloy member is composed of an Mg-based, alloy-element-containing alloy and has an easily corrodible corrosion part and a hardly corrodible corrosionproof part, both formed on the surface by partially changing the corrosionproofness of the member. In the alloy member, the preferential corrrosion of the corrosion part inhibits the corrosion of the corrosionproof part.;COPYRIGHT: (C)2004,JPO&NCIPI
