The influence of structure on the results of the nitriding of ledeburitic chromium steels--Part VI. Ion nitriding of NC11LV steel burnishing after hardening on martensitic structure

摘要

The paper presents the sixth part of results of the research containing the evaluation of the burnishing effect on the properties after ion nitriding of the NC11LV (D2) steel in martensiting state. The specimens were burnishing by the diamante at the power 150 and 400 N, and were nitriding at 400, 440 and 480 °C by four hour. The research show, that the surface deformation accelerates the diffusion process for the nitriding at 400 °C. The nitriding at highest temperature destroyed the burnishing effect. The tempering at 200 °C delayed the diffusion of the nitrogen but hadn't the influence on the structure and properties of the steel.
