Gas Nitriding Behaviour of 34CrAlNi7 Nitriding Steel
Acta 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.
