Aging of a Fe-Mn-Al Steel Using Plasma Nitrocarburizing

Materials Performance and Characterization, 2017
Abstract The aeronautics and automotive industries face increasing demands to lower fuel consumption and consequent CO2 emissions. One method of accomplishing this is to use materials with high strength/weight ratio. Alloys of steels using high manganese and aluminum shows promising results, with densities between 10% and 13% lower than ...

Surface porosity sealing effect of plasma nitrocarburizing on sintered unalloyed iron

Surface and Coatings Technology, 2001
Abstract The influence of pore size on the sealing of P/M superficial pores as a result of plasma nitrocarburizing has been studied. Samples with different particle size distributions were sintered, resulting in surfaces with different pore sizes. The samples were compacted at 600 MPa and sintered at 1150°C for 1 h.

Influence of γ'N and ɛ'N phases on the properties of AISI 304L after low-temperature plasma nitrocarburizing

Journal of Vacuum Science & Technology A, 2023
The surface of austenitic stainless steel AISI 304L has been hardened by adding nitrogen and carbon through the plasma nitrocarburizing process. Plasma nitrocarburizing at low temperatures eliminates the formation of nitrides and carbides of chromium ...

Influence of Plasma Power and Oxygen-Containing Process Gases in Active Screen Plasma Nitrocarburizing with Carbon Solid Source*

HTM: Journal of Heat Treatment and Materials, 2022
Plasma nitrocarburizing by means of active screen technology using an active screen made of carbon fiber-reinforced carbon was carried out by varying the power at the active screen and using oxygen-containing fresh gas components (O2, CO2) in the N2:H2 ...

Plasma post-oxidation process for nitrocarburized layer

Surface and Coatings Technology, 2000
Abstract In the process of the formation of a nitride/oxide layer, the effects of H 2 gas on the oxidation process have been investigated in both a conventional steam process and a plasma oxidation process. In a conventional steam process a single phase of magnetite (Fe 3 O 4 ) has been obtained below a H 2 O/H 2 volume ratio of ∼1:2 while a single

Process control of plasma nitriding and plasma nitrocarburizing in industry

Surface and Coatings Technology, 1993
Abstract Whenever plasma processes are used under continuous production conditions to produce nitrided or nitrocarburized layers, a variety of parameters has to be controlled in order to guarantee consistency of quality. Some of these parameters must be considered during the engineering period of an installation.
