METHOD OF HARD FACING OF STEEL PARTS BY SULPHIDISING Russian patent published in 2009 - IPC C23C28/00 C23C8/62

Abstract RU 2360038 C2

FIELD: chemistry.

SUBSTANCE: invention relates to hardening of refinishing surfaces of steel parts by sulphidising. Sulphidising is carried our within 1-4 hours at 550- 600°C of temperature with using a coating of the following composition, wt %: sulphur pyrites 50, coal clay 50. Before sulphidising a layer of ferrum molybdene coat is electrically precipitated.

EFFECT: enhancement of wearing capacity and reliability of surfaces of steel parts.
