METHOD OF MAKING WEAR-PROOF BIMETALLIC SHEET

摘要

FIELD: process engineering.SUBSTANCE: invention relates to welding. Proposed method comprises arc deposition of coating from wear-proof deposition material on surface of rolled sheet of carbon and low-alloy steels. Rolled sheet is subjected to forced cooling in coat deposition. Cooling medium acts on sheet free surface from below. Said coating is produced in layer-by-layer way. Rate of power input for every said layer is varied subjected to coated rolled sheet temperature. Forced cooling is performed when rolled sheet temperature exceeds tolerable heating temperature. Said tolerable temperature corresponds to that of carbide phase formation temperature. Water solution of sodium chloride is used as cooling medium. Said coating is either solid or intermittent layer.EFFECT: higher wear resistance.4 cl, 9 dwg
