ISBNIn the present study, processing of AISI L stainless steel (ss) has been conducted by intensified plasma-assisted processing (IPAP). The processing parameters (bias voltage, current density, chamber pressure and substrate temperature) of IPAP have been varied in an effort to determine which conditions lead to Intensified plasma assisted processing book formation of a single-phase structure, ‘m’ phase, and evaluate the.

An investigation of the plasma nitriding mechanism under intensified conditions (average particle energy up to eV) was carried out using a triode configuration. The significance of the different physical processes taking place during intensified plasma nitriding, such as sputtering, implantation, defect generation, redeposition and diffusion were investigated experimentally, while.

Nitrided austenitic stainless steel produced by intensified plasma assisted processing has been studied by transmission electron microscopy (TEM), high-resolution TEM, and image simulation techniques.

Cross-sectional TEM studies showed that the nitride layer is composed of a single phase that was found to possess a simple cubic structure. This nitride is produced by. Intensified plasma assisted processing: a novel process in surface coating technology.

Author: De Silva, Eugene. ISNI: Awarding Body: Manchester Metropolitan University Current Institution: Manchester Metropolitan University. Madhavulu and Ahmed observed in their work that the major advantages of the plasma-assisted turning process are the increased metal removal rates, the lower spindle power requirement and the possibility of machining hard and tough metals even when fully hardened and heat-treated.

The authors revealed that PEM leads to a times gain in metal. Electrocatalysts are becoming increasingly important for both energy conversion and environmental catalysis. Plasma technology can realize surface etching and heteroatom doping, and generate highly dispersed components and redox species to increase the exposure of the active edge sites so as to improve the surface utilization and catalytic activity.

This review summarizes the recent plasma. In this mini-review, we have detailed our future focus on the process and energy intensification of plasma-based N-fixation. Three focal points are mainly stressed throughout the review: (I) the integration of renewable energy; (II) the power supply system of plasma reactors and (III) process design of industrial plasma-assisted nitrogen fixation.

Cross-sectional TEM studies showed that the nitride layer is composed of a single phase that was found to possess a simple cubic structure. Written principally for solid state physicists and chemists, materials scientists, and plasma physicists, the book concludes with the outlook for such applications.

Reviews "The authors have managed to write a very informative and inspiring book about a fascinating topic of advanced plasma science and materials processing.". In ultralarge-scale integrated (ULSI) semiconductor fabrication, plasma processing plays a vital role in (1) plasma etching, (2) plasma-assisted chemical vapor deposition (PECVD), and (3) physical vapor deposition (PVD).

In the plasma etching area, there is a very active development of high-density. Plasma-Assisted Materials Processing. Experiments are being conducted to investigate the physical and chemical processes involved in the manufacturing of integrated circuits using a radio frequency (RF) Parallel Plate GEC Reference Reactor.

This work is led by John Foster. Preliminary results reveal that the hybrid plasma-catalytic process requires 21% less electricity than the direct one, while the electric power consumed for the plasma-assisted reaction is the major cost driver in both processes, accounting for ~75% of the total electric power demand.

In order to overcome this trade-off, a plasma‐assisted catalytic process with plasma activation of the catalysts to increase the conversion efficiency while maintaining high energy efficiency has been proposed.

The combination of heterogeneous catalysis and plasma activation, known as plasma catalysis, has attracted increasing interest [28–31]. Plasma assisted N2 fixation, via nitric oxide or NH3 production, is attractive alternative due to inherent non-equilibrium conditions, lower energy demand and the prospect to use an alternative.

The book describes resistance sintering, high-voltage consolidation, sintering by low-voltage electric pulses (including spark plasma sintering), flash sintering, microwave sintering, induction heating sintering, magnetic pulse compaction and other field-assisted sintering techniques.

Using plasma in conjunction with fluorinated compounds is widely encountered in material processing. We discuss several plasma techniques for surface fluorination: deposition of fluorocarbon thin films either by magnetron sputtering of polytetrafluoroethylene targets, or by plasma-assisted chemical vapor deposition using tetrafluoroethane as a precursor, and modification of carbon nanowalls by.

Plasma-enhanced chemical vapor deposition (PECVD) is a chemical vapor deposition process used to deposit thin films from a gas state to a solid state on a substrate.

Chemical reactions are involved in the process, which occur after creation of a plasma of the reacting gases. The plasma is generally created by radio frequency (RF) (alternating current (AC)) frequency or direct current (DC.
