The Influence of the Thermomagnetic Treatments on the Nitrided Superficial Layers Evolution after Wear Process (III)
Two types of steel grades were subjected to a nitriding thermo-chemical treatment after the thermo-magnetic treatments. The structural aspects of the superficial layers of these steels are studied after the friction process ...
Some Experimental Results Concerning the Influence of Surface Coatings on the Wear of Poly-Ether-Etherketone (Peek) Polymeric Gears
Gears made of general purpose Poly-Ether-Ether-Ketone (PEEK) polymeric material and coated on their flanks with a thin layer of different solid lubricants MoS2, graphite (C), BN and PTFE are tested in relation to wear and ...
The Application of CRN Coating in Sliding Pairs under Lubrication Conditions
This work revealed the results of the impact of the formed surface layer CrN and the surfaces layer CrN-steel 46Cr2 “ring” structure. The sliding pairs worked under conditions of lubricating the friction area with Lotos ...
The Influence of Nano-Particle Additive to Lubricating Oils on the Structure and Properties of Friction Surfaces
The article considers the influence of the additive in the lubricating oils Cermet, on tribological properties of a friction pair «cast iron – chrome», which is typical for the cylinder-piston unit of engines. It is shown ...
Analysis of the PM Bearing – Spindle Contact Using Finite Element Method
Using PM (Powder Metallurgy) technologies, new antifriction materials based on iron-copper powders with different addition elements were developed. The elemental powder mixtures were compacted at different pressures and ...
