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.

The Contact Mechanics of Novikov’s Surface‐Hardened Gearing during Running‐in Process

Advances in Tribology, Volume 2018, Issue 1, 2018., 2018
The article is devoted to the analysis of the state of the contact surfaces of the higher kinematic pair in the general case of relative motion, that is, in the presence of rolling, sliding, and twisting, which is characteristic of Novikov’s circular‐screw gears.

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
