Nitriding of AISI 1020 steel: comparison between conventional nitriding and nitriding with cathodic cage [PDF]
Materials Research, 2014 Cylindrical samples of AISI 1020 steel were nitrided, using the techniques of conventional plasma nitriding and cathodic cage. In the latter, the samples are kept at floating potential, inside of a cage that works as a cathode and to shield the samples ...

The effect of novel composite pretreatment on performances of plasma nitrided layer
Journal of Materials Research and Technology, 2020 Novel composite pretreatment combining laser shock peening and pre-oxidation was primarily adopted prior to plasma nitriding for 42CrMo steel. Optical microscope, scanning electron microscope, vickers microhardness tester and wear tester were used to ...

HARDNESS OF NITRIDED LAYERS TREATED BY PLASMA NITRIDING
Acta Polytechnica CTU Proceedings, 2020 Stainless steels, particularly the austenitic stainless grades are widely used in many industries due to good corrosion resistance, but very poor mechanical properties as surface hardness and wear resistance limit its possible use. Plasma nitriding is one of the few ways to increase the surface hardness of these steels, even though this will affect its

Metallurgical response of an AISI 4140 steel to different plasma nitriding gas mixtures [PDF]
Materials Research, 2013 Plasma nitriding is a surface modification process that uses glow discharge to diffuse nitrogen atoms into the metallic matrix of different materials. Among the many possible parameters of the process, the gas mixture composition plays an important role,

Changes of Structure and Physical-Mechanical Properties in Alloy Steels Thermochemically Treated by Plasma Nitriding [PDF]
MATEC Web of Conferences, 2021 Plasma nitriding is a method of surface modification using a glow discharge technology to introduce nitrogen into the surface of a metal, which subsequently diffuses into the material.

Surface modification of titanium by plasma nitriding
Materials Research, 2003 A systematic investigation was undertaken on commercially pure titanium submitted to plasma nitriding. Thirteen different sets of operational parameters (nitriding time, sample temperature and plasma atmosphere) were used. Surface analyses were performed
