METHOD OF PRODUCING HEAT-RESISTANT COATING ON STEEL Russian patent published in 2020 - IPC B23K20/08 C23C10/48 

Abstract RU 2725501 C1

FIELD: technological processes.

SUBSTANCE: invention relates to the technology of producing coatings on metals using explosive energy and can be used in making parts of power and chemical plants having high heat resistance. Two-layer stack is made out of fixed steel plate and 0.8–1 mm-thick fechral driver plate above it. Welding is carried out by explosion of plates at specified speed of detonation of explosive charge. Explosive charge height and the welding gap between the plates are selected from the condition of obtaining the specified speed of their collision. Method includes aluminising fechral layer of welded billet in AL2 silumin melt and heat treatment of obtained billet.

EFFECT: technical result is increase in the heat-resistant coating working temperature in the oxidizing gaseous media and simplification of the coating production method.
