The paper investigates the influence of ion-nitriding process on microstructure, corrosion resistance, and tensile strength at elevated temperatures Haynes 282 nickel superalloy specimens produced by Direct Metal Laser Sintering (DMLS) technique. study was performed for two conditions, i.e., as-built DMLS method + covered a layer containing CrN Cr2N phases. An analysis surface morphology reveal...

H-13 steel surface was duplex-treated using Plasma Nitriding (PN) and PVD coatings to solve the thermal fatigue problem faced in die-casting applications. Chromium-based multilayer CrN/Cr (m-CrN) multi-component aluminium–titanium-based AlTiN (m-AlTiN) were deposited a cathodic arc deposition technique after plasma nitriding with different case-depths of 50 µm 200 µm. The structural, tribologic...

It is known that nitro-oxide coatings were developed based on nitriding, which are obtained using a two-stage technology consisting of nitriding at the first stage process and vaporization second stage. Such processing provides high physical mathematical characteristics hardened parts. This technological was improved by us due to preliminary oxidation, made it possible accelerate production nit...

A new alloy for drive-train applications with a significant addition of vanadium is presented. The influence to air-hardening forging steels investigated and discussed. For the investigations, laboratory melt casted forged into rod. mechanical properties microstructure are described compared vanadium-free reference from previous study. component shows high strength hardness in as-forged state (...

The article deals with a possibilities of an enhancement functional properties highly stressed components by specific combination surface technology. Two technologies such as plasma nitriding and laser shock peening were selected for the experiment. Those applied upon steel 42CrMo4 frequently utilized in manufacturing strained components. Properties obtained tested following experimental method...
