Abstract

Abstract: By testing the dimensional accuracy, roughness and strength of nitrided parts before and after oxidation treatment, the applicability of oxidation treatment after nitriding in actual production was investigated. The results show that the influence of the process on the dimensional accuracy and roughness of parts is small, but the influence on the strength is large. Therefore, the oxidation treatment after nitriding is not suitable for the quenched and tempered workpieces and standard fasteners whose tempering temperature is lower than the oxidation temperature.

Key words: nitriding and post-oxidating, dimensional accuracy, roughness, strength, fastener strength
