Abstract

The invention provides a corrosive liquid, a preparation method of the corrosive liquid and a corrosion process of the corrosive liquid applied to Incone625 nickel alloy, and belongs to the technical field of corrosion. The invention relates to a corrosive liquid, which is characterized by comprising the following aqueous solutions of substances with the following concentrations: 30-50ml / L of nitric acid with the mass fraction of 65%-68%, 500-550ml / L of hydrochloric acid with the mass fraction of 35%-36.5%, 130-160g / L of industrial grade anhydrous ferric chloride and 5-10ml / L of a surfactant. The method has the advantages that the Inconel 625 nickel alloy is difficult to corrode or high in efficiency and can be controlled when the Inconel 625 nickel alloy is corroded.

Description

technical field [0001] The invention belongs to the technical field of corrosion, in particular to a corrosion solution, a preparation method of the corrosion solution and its application in the corrosion process of Inconel625 nickel alloy. Background technique [0002] Inconel 625 alloy is a nickel-chromium-iron nickel-based corrosion-resistant and heat-resistant alloy with a nickel content of more than 58%, a chromium content of 20-23%, and a molybdenum content of 8-10% and a molybdenum content of 3-4%. Its unique composition makes it highly resistant to corrosive substances. Common inorganic acids such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid and mixed acids have very little corrosion rate to this alloy. [0003] Due to its excellent corrosion resistance, this metal is widely used in military industry, aerospace, marine industry, etc. However, due to its involvement in military industry, aerospace, etc., the relevant corrosion technology is kept c...
