  • Deposition – A question of choice

    Often the first question in any discussion on deposition processes is which technique is best suited. Often the answer to this question is clear, but in some cases it requires a detailed understanding of the application and production targets in order to give a qualified answer. Typical questions to understand which technique to use are: What is the end application (often there are well ...

  • Our Go Green initiative ‘goes electric’!

    As sustainable travel becomes a more pressing global issue, we’ve taken action and made it a reality here at Plasma Technology with our Go Green initiative! Two recent initiatives have been put in place at the company near Bristol with the support of local authority, North Somerset Council. With over 100,000 electric vehicles now on our roads, a greater choice of vehicles, and more charging ...

  • Fly Ash Treatment – Plasma Torches versus Graphite Electrodes

    Background Plasma generating devices have to be designed to tolerate incredibly harsh conditions during operation and in particular very high heat loads and temperatures around the arc. However, when used in the vitrification of highly chlorinated materials the challenge is even greater than in other applications. The combination of high ...

  • 25 Years of Success – Outokumpu Stainless DC Plasma Smelting Facility

    Design is not just what is looks and feels like. Design is how it works. Between 1982 and 1987, British Steel (Outokumpu today) made extensive investigations into the treatment of steel dust. Their research was far and wide and covered off many various methods of recycling, including alternative to plasma technologies. But, in 1985, they engaged Tetronics International to carry out a ...

  • New applications of beam–plasma systems for the materials production

    Beam–plasma systems (BPS) are known to be a great prospect for the surface modification of organic and inorganic materials. The present paper considers the plasma–assisted synthesis and deposition from the point of view of the hybrid materials production. Pilot setups in which the above processes occur in the electron–beam plasma (EBP) and combined plasma (CP) are described. The results of the ...

  • CIWM Feature: Plasma Power - Dr Deegan gives a flavour of what plasma technology can offer

    Sustainability… what does this mean? It is often a term that means many different things to different people and organisations based on their perspective. When examined in detail, the definition is quite complex, something that Chartered Environmentalists will be more than familiar with. It is also something that is linked into addressing concerns around the subjects of strategic ...

  • Our HVOF equipment takes coating to another level in Scandinavia case study

    KMAB (Karlstad Metallisering AB) in Sweden was the first company in Europe to purchase our CJK5 HVOF equipment. KMAB is a company with tradition that has been working with thermal spraying since 1958. Besides thermal spraying, KMAB are also working with machining, balancing and teflon coatings. Today the company is using plasma, flame, arc spraying and HVOF in their daily work. The parts that ...

  • O- density measurements in the pulsed-DC reactive magnetron sputtering of titanium

    The importance of electronegative species in technological plasmas is currently of great interest, both from a theoretical and experimental point of view, with much of the recent work concentrating on reactive ion etching discharges. However, other very important plasma systems have been somewhat neglected by scientist and engineers in terms of the role of negative ions, for instance, pulsed ...

  • Waste Advantage Magazine- The use of Thermal Plasma Technology for treating APC Residues

    The  growth in Energy from Waste plant capacity is leading a corresponding increase in the generation of Air Pollution Control (APC) Residues, making it one of the fasted growing waste sectors in the UK. In this article published in Waste Advantage Magazine, Dr Tim Johnson from Tetronics discusses how plasma technology is one solution to this ...

  • The Chemical Engineer - The Forgotten Earth

    Demand for minerals is on the rise, as is their price. No wonder then that industry is looking to extract minerals from what once would have considered waste. In this article, Dr Tim Johnson of Tetronics explains how plasma technology plays its ...

  • The Plasma Processing of Steel Plant Wastes

    ABSTRACT: Electric arc furnace (EAF) dusts, have been successfully treated in plasma-fired carbothermic reduction furnaces to recover metal values. Although the technology is equally applicable across the range from plain carbon to stainless steels, historically, it is the latter that has been the more commercially successful. Because the plasma heat source is independent of process chemistry, ...

  • Large-scale synthesis of nanopowders by transferred arc thermal plasma

    The present work describes the preliminary results on large-scale synthesis and characterisation of copper (Cu) and aluminium nitride (AlN) nano powders by transferred arc thermal plasma technique. The transferred arc was used to vaporise the precursor materials (Cu, Al metal 99.9% pure). Nano particles are formed in the gas phase as a result of homogeneous nucleation. The vapours of Al were ...

  • Relativistic energy-momentum: the concepts of conservation versus frame invariance

    The use of relativistic frame invariants is very well established, especially when it comes to the energy-momentum. In the following paper we clarify the terms 'conserved' and 'frame invariant' and we explain the differences between the two concepts. Our paper is divided into three main sections. In the first section we explain the notion of frame invariance. In the second section we explain the ...

  • Synthesis and characterisation of nano alumina dental filler

    The production of alumina nanoparticles using a low power plasma torch and creating a nanocomposite for use in dental applications were investigated. Upon fabricating the nanocomposite based on alumina nanoparticles, the mechanical properties were studied using instrumented nanoindentation and compared to three standard dental fillers. Several nanocharacterisation techniques were employed in the ...

  • Nonthermal plasma reactors and plasma chemistry

    The main goal of this paper is focused in reviewing the last 22 years of the use of nonthermal plasma reactors as alternative technologies for the treatment of residual fluid substances, regarding the destruction of hazardous compounds or the synthesis of other valuable compounds. The electrical discharge processing has emerged as alternative plasma-based technologies. Electrical discharges can ...

  • Feasibility of a CHP driven industrial park based on exergy analysis

    Industrial zones are manufacturing plants clustered in a given part of a city. Such clustering is primarily dictated by zoning regulations that tend to isolate residential, business, and industrial neighbourhoods. A number of properly matched manufacturing plants can be clustered within a given proximity with a primary objective of optimising their energy use. As secondary goals the cluster may ...

  • Pyrolysis processing of used old tyres by thermal plasma technology

    Thermal plasma pyrolysis of used old tyres was studied in a nitrogen plasma reactor in order to evaluate the material and energy recycling potential. The main gaseous products from thermal plasma pyrolysis of used old tyres were identified by chromatography as H2, CO, CH4, C2H2, ...

  • Techniques for processing industrial waste using arcplasma generated by the twelve-phase alternating current

    We have already presented an arc-discharging plasma generator, generally called a thermal plasma generator which is constructed by the six-phase alternating current power supply(Matsuura et al, 1994a, 1997). A more effective thermal plasma generator can construct by expanding this concept. As an example, this small power supply system has been presented in reference (Matsuura et al., 1994b). In ...
