A detailed analysis of the structural, morphological characteristics and micro-abrasive wear behavior of nitrided layer produced in α (CP–Ti), α+β (Ti–6Al–4V), and β (TNZ33) type Ti alloys

open access: yesJournal of Materials Research and Technology, 2023
The present work aimed to create a hard surface on a titanium surface via plasma nitriding to improve microhardness and wear properties of the as-cast (α-CP-Ti (CP–Ti), α+β-Ti6Al4V (Ti–Al–4V), and β-Ti-33Nb–33Zr (TNZ-33) samples.

Surface Treatment of Tool Steel in Controlled Plasma Nitriding Environment

open access: yesTribology Online, 2008
Nitriding of tool steel was investigated in a controlled electron beam excited nitrogen plasma environment. The samples were nitrided in two distinct regions, a region with high plasma density and a region with low plasma density called the irradiated ...

Plasma-Nitriding Properties of CoCrFeMnNi High-Entropy Alloys Produced by Spark Plasma Sintering

open access: yesMetals, 2020
High-entropy alloys (HEAs) were fabricated by powder metallurgy using gas-atomized powder and spark plasma sintering (SPS) followed by surface modification (plasma nitriding) of the sintered sample.

Surface modification of austenitic steel by various glow-discharge nitriding methods

open access: yesMedžiagotyra, 2015
Recent years have seen intensive research on modifying glow-discharge nitriding processes. One of the most commonly used glow-discharge methods includes cathodic potential nitriding (conventional method), and active screen plasma nitriding. Each of these

PLASMA DEPOSITION OF SILICON NITRIDE [PDF]

open access: yesLe Journal de Physique IV, 1991
This paper reports on the preparation and characterization of thin films of silicon nitride deposited on heated silicon substrates from Si (CH3)4-NH3-H2 mixtures activated at room temperature by an a.c. discharge at low frequency. The films were deposited at 800°C.

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Friction and wear behavior of duplex-treated AISI 316L steels by rapid plasma nitriding and (CrWAlTiSi)N ceramic coating

open access: yesResults in Physics, 2021
Due to their high corrosion resistance, non-transformation, and non-magnetism, austenitic stainless steels can meet the service requirements. However, their low hardness and poor wear resistance impose serious drawbacks. A combination of plasma nitriding
