Abstract

DC60 (29/11/56) This invention Provide a method to modify the skin that can provide resistance in low cost carburization process with alloy steel base material used to make carburizing parts in furnaces; used in carburizing furnaces, surface treatment equipment and carburization parts in the furnace problem has been Modified by surface modification methods, including the aluminum annealing process. as a base material coating Type 1 nickel alloyed steel with molten aluminum To create an aluminum-coated film 2 on alloy steel-type 1 base material, the process of removing excess aluminum It is the use of heat to melt the film. Aluminum coating 2 to remove excess film of molten aluminum coating 2, and the process of creating a diffusion layer is to heat the hot alloy steel material 1 and from there. excess of film Aluminum coating 2 will be eliminated. at higher temperatures The heating temperature of the elimination procedure excess aluminum to distribute the elements that come together of the base material consists of steel 1 and aluminum contained in the aluminum coating film 2 together to form a diffusion layer 3.
