| titleOfInvention | A kind of preparation method of diffusion barrier layer suitable for large-scale components |
| abstract | A preparation method for a diffusion barrier layer suitable for large-scale components, preparation of aluminizing agent: put aluminum-iron blocks into a container, add ammonium bifluoride with a mass percentage of 0.5% to 1.0% of the aluminum-iron blocks, and then add water until the aluminum is diffused. The surface of the iron block is then heated in a heating furnace and kept at 270-330°C until it is boiled dry; a roasting at 700-900°C is carried out between two activation treatments; degreasing: parts and components that need to be aluminized, including test For example, use organic solvent to clean the surface dirt and oil; Liquid sand blasting: Before aluminizing, the components need to be blasted by liquid sand, and the wind pressure should not exceed 0.3Mpa; Gas phase aluminizing: 900～1050℃, heat preservation for 1～3.5 hours , the relative pressure in the furnace is controlled between 0.002MPa ~ 0.01Mpa. The advantages of the invention are: the formed alumina barrier layer is complete, continuous and dense, and can exist stably at high temperature for a long time; it can be used for the preparation of the diffusion barrier layer of large components; the cost of raw materials is low, the process is simple, and the production efficiency is high. |
