Alloying up to 10 mm Depth of Cast Surface of Steels 45 and U8 with Ferrum Boride at Consumable Patterns Casting

Dementiev V.B., Ovcharenko P.G., Leshchev A.Y.


A method of surface alloying of required area of cast section to a specified depth is considered. The method is carried out by inserting thin metal plates borided for increasing their hardness, into a expanded polystyrene mold with a constant pitch. During melt loading, the alloyed layer with given depth, which has high hardness due to ferrum boride presence, is formed.
