Improvement of Wear and Corrosion Resistance of Austenitic Stainless Steel by Combined Treatment Using Electron Beam Cladding and Subsequent Gas Nitrocarburizing

Advanced Engineering Materials, Volume 21, Issue 12, December 2019., 2019
Herein, a solution for locally increasing the wear resistance of austenitic stainless steel by electron beam cladding of a Co‐based alloy and subsequent gas nitrocarburizing is elaborated. Furthermore, the corrosion resistance can be improved as a result of the combined treatment process.

Morphology of the DIN 100Cr6 Case Hardened Steel after Plasma Nitrocarburizing Process [PDF]

Materials Research
Nitrocarburizing is considered one of the most important thermochemical treatments for surface modification of metallic materials and involves the simultaneous diffusion of nitrogen and carbon onto the surface. Understanding and controlling the formation

Microstructure and corrosion behaviour of plasma‐nitrocarburized sintered steel

Materials and Corrosion, 2004
AbstractPowder characteristics and manufacturing processes determine the microstructure, and therefore, the physical, chemical, and mechanical properties of sintered steels. In particular, porosity and corrosion resistance are intimately related, since the contact area between substrate and electrolyte significantly affects the corrosion resistance of ...

Friction Characteristics of Machined Metal with Different Surface Morphologies

Advances in Materials Science and Engineering, Volume 2015, Issue 1, 2015., 2015
This study examined the friction characteristics of SAE1045 medium carbon steel processed by milling machining (MM) and abrasive jet machining (AJM). Friction experiments were conducted with variations in load and friction distance. Experimental results show that micro craters produced by AJM help retain lubricant on workpiece surface and thus decrease

Lower corrosion resistance of the nitrocarburized layer formed on two supermartensitic stainless steel types [PDF]

REM: International Engineering Journal
The aim of this study was to verify the pitting corrosion behavior in the surface layers obtained by plasma nitrocarburizing at 400 and 450 °C/5 h on two types of super-martensitic stainless steel, namely micro-alloyed (Nb-SMSS) and unalloyed (SMSS). The

Study of Multilayer Treatments of Nitrocarburizing with N and Si-doped DLC Films in Improving the Wear Resistance of AISI M2 Steel [PDF]

Materials Research
Diamond-like Carbon (DLC) films demonstrate substantial hardness, minimal friction, and exceptional wear resistance when applied to metal substrates; however, they face challenges related to inadequate adhesion.

Effect of Carbon on the Compound Layer Properties of AISI H13 Tool Steel in Pulsed Plasma Nitrocarburizing

, 2015
Due to the mechanical and inertness properties of the epsilon-Fe(2-3)N phase, its formation as a compact monolayer is most wanted in plasma surface treatments of steels. This phase can be obtained by the inclusion of carbon species in the plasma. In this

Corrosion studies of duplex surface-treated M420 stainless steel by plasma nitrocarburizing and WCrAlTiSiN multilayer coating

Results in Surfaces and Interfaces
M420 stainless steel has good mechanical properties, but its corrosion resistance is poor, which limits its application in marine conditions. Single-technology processing has been unable to meet the development needs of modern industry.
