Corrosion-inhibited iron-based members and method of producing the same

摘要

A corrodible iron-based work such as a cylinder rod is subjected to hard chrome plating, heat-treatment by high frequency heating or baking at a temperature of not less than 150 DEG C. (e.g. 170 DEG to 600 DEG C.), resin impregnation treatment and finish buffing in that order to produce a corrosion-inhibited member. In the impregnation step, a thermosetting resin may be impregnated under subatmospheric pressure. After the impregnation step, the thermosettable resin or sealant may be cured in a curing step. The present invention provides for an remarkably high degree of corrosion resistance even though the thickness of the hard chrome plating layer is small.
