Abstract
The invention relates to a corrosion-resistant iron-based amorphous alloy coating. The corrosion-resistant iron-based amorphous alloy coating comprises the following components of Fe, Cr, Mo, Ni, C, B and Y, wherein the atomic number ratio of the various components is (46-50): (10-12): (10-12): (4-6): (13-17): (5-7): (1.8-2.2). The invention further provides a preparation method of the corrosion-resistant iron-based amorphous alloy coating. The preparation method comprises the following steps: carrying out raw material proportioning, and carrying out smelting through a vacuum smelting furnace to obtain an iron-based alloy cast ingot; preparing the iron-based amorphous alloy cast ingot obtained in the step S1 into iron-based amorphous alloy powder by utilizing a vacuum gas atomization method; carrying out cleaning, sand blasting, roughening and preheating treatment on the surface of a steel matrix; and preparing the surface of the steel matrix into the corrosion-resistant iron-based amorphous alloy coating by utilizing a supersonic flame spraying technology. The invention further provides application of the corrosion-resistant iron-based amorphous alloy coating.
Description
technical field [0001] The invention relates to the field of amorphous alloy coating and corrosion protection, in particular to a corrosion-resistant iron-based amorphous alloy coating, a preparation method and an application thereof. Background technique [0002] The marine environment is extremely complex. Seawater covers 70% of the earth's surface. Sea-related equipment has been in harsh marine environments for a long time, and corrosion damage cannot be avoided, which seriously affects the reliability and life of sea-related equipment and brings huge economic losses. . Explore corrosion-resistant materials suitable for more sea-related equipment such as ships and oil pipelines working in complex seawater environments, thereby prolonging the service life of sea-related equipment to reduce economic losses and safety problems caused by corrosion problems. The development of my country's ocean engineering field is very important. Using advanced surface technology to locally...
