СПОСОБ ПОВЫШЕНИЯ ИЗНОСОСТОЙКОСТИ ЛИСТОПРАВИЛЬНЫХ РОЛИКОВ

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention refers to methods of treatment of planing machine rollers. The method includes preparing of roller body surface and application of strengthening coating. Preliminary preparation of roller body surface is performed by means of its blowing-off under pressure with iron shot of 180...200 mcm fraction. Further two-layer strengthening coating is applied by the method of gas-detonation sputtering. Also the interior layer of coating is applied with powder of tungsten carbide of 55...65 mcm fraction obtaining thickness of the interior layer of 15...25 mcm. The exterior layer is applied with copper powder with additives not more, than 0.6%, obtaining the thickness of the exterior layer of 8...10 mcm. ^ EFFECT: upgraded wear resistance of sheet planing roller. ^ 1 ex
