METHOD OF HARDENING OF METALLIC SURFACES Russian patent published in 2005 - IPC

Abstract RU 2261939 C1

FIELD: methods of hardening of restored surfaces of steel products.

SUBSTANCE: the invention is pertaining to the field hardening of metallic surfaces of steel products. The offered method includes a cyanidation of the electrodeposited layer of an iron-molybdenum coating within 1-4 hours at the temperature of 600-650°C with usage of a paste of the following composition (in mass %): yellow bloody salt - 30...45, sodium carbonate - 8...10, calcium carbonate - 5...10, carbon-black - up to 57. The technical result of the invention is boosting hardness and a wearability of surfaces of steel component parts.

EFFECT: the invention ensures an increased hardness and a wearability of surfaces of steel component parts.
