Gas Nitriding Behaviour of 34CrAlNi7 Nitriding Steel

open access: yesActa Physica Polonica A, 2014
In this study, gas nitriding behavior of 34CrAlNi7 10 steel was investigated. Single stage processes were carried out at 500 ◦C, 520 ◦C and 540 ◦C for 10, 20, 30 h, respectively. Nitrogen activity on surface was controlled by the nitriding potential KN which is known as thermodynamical control parameter for controlled gas nitriding process.
