Nickel based anti-corrosion arc silk material

Abstract

The invention relates to a nickel based anti-corrosion arc silk material, which is characterized in that a flux core comprises the following ingredients in percentage by mass: 56 to 74 percent of metallic nickel, 21 to 40 percent of metallic chrome, 5 to 9 percent of metallic aluminum, 2 to 4 percent of metallic copper, 2 to 6 percent of boron, 2 to 6 percent of magnesium and 0.5 to 1 percent of Y. The nickel based anti-corrosion arc silk material solves the problem of surface protection of petrochemical equipment under the conditions of high-temperature ablation and high-temperature corrosion and simultaneously solves the problems of equipment and pipeline salt solution ion point corrosion, and the high-temperature oxidation performance and the chloride ion resistance performance are both better than those of high-nichrome solid wire material PS45 and Q235 low-carbon steel.

Description

technical field [0001] The invention belongs to the field of surface engineering in material processing engineering and is mainly applied to the surface protection of petrochemical equipment and parts. Background technique [0002] Copper-nickel alloy is a commonly used anti-corrosion and anti-fouling material. The toxicity of copper ions reduces the adsorption of microorganisms on its surface. At the same time, copper-nickel alloy has good corrosion resistance. Filters made of this material prevent microbial contamination And entering the system is an effective method; the traditional product will appear irregularly shaped corrosion pits after a period of use. There is a layer of iridescent corrosion products on the surface, which is due to the copper remaining after the substrate is severely denickeled; this Corrosion is receiving more and more widespread attention from society. In the petrochemical industry, many equipment and parts are corroded by solutions containing c...
