Abstract

An anticorrosion technology for the surface of submarine features that the surface of submarine is integrally treated, and includes such steps as chemically plating a copper layer with 3-5 microns of thickness, and chemically plating a Ni-W-P layer with 50-80 microns of thickness. Its advantages are high resistance to seawater corrosion, high hardness and strength, and high antiwear nature.

Description

The surface anticorrosion processing method of submarine
Technical field: the effect in modernized war of conventionally-powered submarine and nuclear-powered submarine increases day by day, and especially modern war makes submarine become the indispensable equipment of modernized naval, also is the symbol of a national naval military strength.This project belongs to modernization of national defense field.
Background technology: because submarine slips into b.s.l. work for a long time.The submarine surface is subjected to the parasitic erosion of corrosion and ocean of seawater for a long time, the submarine shell mostly is high-quality alloy steel and is welded, the submarine surface is easy to be corroded under the acting in conjunction of surface stress, composition difference, seawater, ocean parasite and huge sea pressure, influence submarine work-ing life even the safety that directly jeopardizes submarine.The surface anticorrosion of submarine becomes the manufacturing problem of being badly in need of solution of countries in the world submarine for this reason.The leader of General Armament Department of PLA also pays much attention to the anticorrosion research on submarine surface.Because the curved transition of submarine profile is big, the surface anticorrosion of submarine substantially all is the method that adopts topcoating both at home and abroad.Though different types of coating has improved the antiseptic power on submarine surface, also differ greatly with the requirement for anticorrosion on submarine surface.
Summary of the invention: the present invention proposes the new processing method of a kind of submarine surface anticorrosive.The object of the present invention is achieved like this, and the first step adopts the method for electroless plating to plate the metallic copper that a layer thickness is 3～5 μ m at the submarine integral surface.Second step was the nickel-tungsten-phosphorus composite bed that plates one deck 50～80 μ m on copper plate with the method for electroless plating, well-known metallic nickel is the best metallic substance of anti-seawater corrosion, the anti-seawater corrosion ability that any chemical coating all is not so good as metallic nickel is strong, for improving intensity, hardness, the resistance to corrosion of nickel layer, adopt the method for the compound plating of Ni-W-P, at the Ni-W-P composite bed of submarine integral surface plating one deck 0.02～0.2mm, its resistance to corrosion greatly strengthens.
