Abstract (en)
[origin: WO03078676A1] The invention relates to a method for the Alfin processing of components (40) in an Alfin processing bath (20), which are provided in order to be poured in a casting part made of aluminium, wherein the oxygen present in the components is at least partially removed before placing the components in the Alfin processing bath by heating the components in an inert gas atmosphere. As a result, defective points on the Alfin processing layer caused by local oxidation can be prevented. Said method can be carried out at low cost in a continuous operation through a continuous furnace (10) charged with inert gas, the Alfin processing bath (20) being simultaneously arranged therein.
