METHOD OF MAKING METAL COATING ON TILLER CUTTING EDGES

摘要

FIELD: process engineering.SUBSTANCE: invention relates to welding. Proposed method comprises producing briquette-shape filling material. Briquettes consist of the mix of powders wherein nano-sized hardening particles make 0.1-0.4% of surfacing metal amount. Binding component represents 4-5%-water solution of carboxymethyl cellulose. Then, briquettes are dried to complete hardening. Briquette is placed onto facing surface. Then coating bead is built up by complete dissolution of filler briquette and, partially, of article metal with penetration depth of 0.1-0.5 mm. Every other briquette is placed on facing surface after dissolution of previous briquette. Now, bead after bead is built up to make two and more layers of coating.EFFECT: higher efficiency owing to continuous surfacing without cooling.3 cl, 1 tbl, 1 ex
