BORON-NITRIDING TREATMENT METHOD FOR STEEL AND HIGH ALLOY STEEL AND BORON-NITRIDING TREATMENT ARTICLE USING THE SAME CAPABLE OF IMPROVING ABRASION-RESISTANCE AND CORROSION-RESISTANCE

摘要

PURPOSE: A boron-nitriding treatment method for steel and high alloy steel and a boron-nitriding treatment article using the same are provided to improve the corrosion-resistance and mechanical properties of steel by boron-nitriding and ion-nitriding the surface of high alloy steel.;CONSTITUTION: A boron-nitriding treatment method for steel and high alloy steel is as follows. Boronizing mixed powder is prepared(S10). A boron compound layer is formed on the surface of a treatment article required for boronizing treatment(S20). The powder and the treatment article are put into a sealed container(S21). The sealed container is put into a furnace and is heat-treated(S22). The heat-treated treatment article is cooled(S23). A boron-nitriding compound layer is formed by adding nitrogen to the boron compound layer through ion-nitriding treatment(S30).;COPYRIGHT KIPO 2012
