Surface Hardening by Induction

open access: yesTransactions of The Electrochemical Society, 1941
High frequency induction heating is ideal for localized surface hardening of crankshafts and a wide variety of machine parts. There is practically no distortion nor scale formation. Time cycles of only a few seconds are maintained by automatic regulation. The usual and expensive pretreatment, such as copper plating and carburizing, is eliminated.

Effect of Surface Hardening by Gas Nitriding on the Fatigue Resistance of Low Alloy Steel EN 1.8509 (41CrAlMo7-10)

open access: yesInternational Journal of Emerging Research in Engineering, Science, and Management
In this research, the fatigue resistance of low alloy steel was improved by using surface hardening by gas nitridation at different temperatures, 475 to 610°C, and in a medium containing 70% nitrogen and 30% hydrogen.

Bimetallic junctions [PDF]

open access: yes, 1977
The formation of voids through interdiffusion in bimetallic welded structures exposed to high operating temperatures is inhibited by utilizing an alloy of the parent materials in the junction of the parent materials or by preannealing the junction at an ...

Surface Hardening for Low Carbon Steel (A3k) by Yag: Nd Pulse Laser Thermal Activation

open access: yesThe Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2008
The paper is based on experiments for surface hardening on A3k (low carbon steel) samples using YAG:Nd pulse laser. A small x-y moving system conducted by PC was made for sample scanning, relative to fixed focused laser beam.

Effect of surface modification of 5KHV2S steel on the mechanism and intensity of contact wear

open access: yesMetalurgija
The paper presents the experimental study of the contact wear of 5KHV2S steel after surface modification. It is shown that without hardening of the surface layer, 5KHV2S steel is capable of satisfactory operation when a pulsating contact stress of 970 ...
