Abstract

The invention discloses a surface anticorrosion modification method for a stainless-steel flagpole. The method comprises the following processes: A. polishing: polishing the surface of a stainless-steel flagpole until the surface is smooth, bright and clean; B. cleaning: first cleaning with lye, then with hot water, and then with cold water; C. activating: performing surface activation processing with a chemical activation plus nickel plating method; and D. chemical plating: putting the flagpole in a heated chemical plating solution for nickel-phosphorus chemical plating. Thanks to the provided method, through the surface activation processing with the chemical activation plus nickel plating method, a nickel-phosphorus chemical plating is combined better, and the flagpole is enhanced in anticorrosion property, so that the surface beauty and service life of the flagpole are substantially improved.

Description
