A method for producing an alloy coating film having high strength high corrosion resistance and low thermal expansion and an alloy coating film produced thereby.

摘要

The present invention relates to a method for manufacturing an alloy coating film having high strength, high corrosion resistance, and low thermal expansion by a plating process and an alloy coating film produced thereby, more specifically, to prepare a Fe-Ni alloy coating film by an electroforming process, such Fe -By adding one or two or more additive metals of C, Cu, Cr, Co to the Ni alloy plating solution, and then heat-treating it, the high strength and high strength by the plating process to have higher strength, higher corrosion resistance, and lower thermal expansion than before It relates to a method for manufacturing an alloy coating film having high corrosion resistance and low thermal expansion and an alloy coating film produced thereby.
