Effects of Using Alternative Extreme Pressure (EP) and Anti-Wear (AW) Additives with Oxy-Nitrided Samples [PDF]

, 2018
Oxy-nitriding is a widely used industrial process aiming to improve the tribological properties and performance of components. Previous studies have shown the effectiveness of the treatment with friction and wear performance, but very few have focussed ...

CHARACTERIZATION OF NITROCARBURIZED COATING BY PLASMA ELECTROLYTIC SATURATION

Acta Metallurgica Slovaca, 2018
Plasma electrolytic saturation (PES) is an atmospheric pressure plasma deposition which is used for fabrication of nanostructural coatings. This process starts with the appearance of some sparks on the surface and finally by the formation of plasma envelope around the sample, particles and free radicals bombard the surface and diffusion takes place ...

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.

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

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 ...
