  • CNC Cutting Service

    The commonly used CNC cutting services are mainly divided into flame cutting services and plasma cutting services, each of which has its own advantages. What is the main difference? Principles of CNC cutting service Flame cutting is the oldest form of thermal cutting. It raises the temperature of the flame through the combination of ...

  • Revisited: Why we should be recycling more nickel

    Dr Tim Johnson has revisited his nickel blog for CIWM magazine Earlier this year we released a blog that explained why we should be recycling more nickel. The blog was written by Dr Tim Johnson and proved to be very popular in the wider metallurgy community. The blog explained how important nickel can be, and how plasma technology can help recycle nickel in a sustainable way. Dr Tim Johnson has ...

  • How can lead be so crucial, but also so toxic?

    Why is everyone talking about lead? Not long ago, like so many historic buildings in the UK, a local parish church near to where I live had the lead stolen from its roof.  Sadly, this is not so unusual and all the more distressing in this case, both because it holds special memories as the church where my wife and I were married, and also because the lead was stolen during heavy ...

  • 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 ...

  • Keeping APCr out of Landfill

    The CIWM have recently featured an article by our very own Dr David Deegan in the latest edition of their magazine. The article explains why Tetronics International were unhappy to be informed recently that Defra ministers had taken the decision not to remove the ...

  • Titanium Demand on Rise for Additive Manufacturing Printing: How it’s Made? Titanium Plasma Atomization.

    Plasma atomization is used in many applications, including 3D printing. First developed in 1998, this technique has risen to become the industry standard process for creating reactive metal powders suitable for 3D printing. Learn how plasma atomization works and why you need an oxygen monitor to stay safe with plasma atomization.  How Plasma Atomization Works ...

  • Atomic Layer Etching – Changing the Art of the Possible

    The society of vacuum coaters (SVC) deserves to be better known. It was founded in 1957 during a surge in the use of vacuum coating techniques such as sputtering and evaporation. The techniques go back a very long way: that man Edison filed a patent for coating phonograph cylinders in 1892 (It will never catch on). Did you know that the shiny surface inside your crisp packet is a vacuum ...

  • UV LEDs making waves with clean water

    Oxford Instruments systems now facilitate water purification technology With World Earth Day last week I’ve decided to make this weeks blog about how new technology is being used to enhance people’s lives in a fundamental way. The UN recognises that clean drinking water is a global issue with over ...

  • Degradation kinetics of organic dyes in water by high voltage atmospheric air and modified air cold plasma

    High voltage atmospheric cold plasma (HVACP) is a novel, non-thermal technology which has shown potential for degradation of various toxic components in wastewater. In this study, HVACP was used to examine the degradation kinetics of methyl red, crystal violet and fast green FCF dyes. HVACP discharge was found to be a source of reactive nitrogen and oxygen species. High voltage application ...

  • New Paper: Atomic layer etching using advanced plasma etch technology

    Scientists at Plasma Technology demonstrate Atomic Layer Etching (ALEt) of Silicon, using advanced technology  and plasma process knowledge. Read the article in JVST by Andy Goodyear and Dr Mike Cooke, Oxford Instruments Atomic layer etching using plasma is a cyclical etching process of gas dosing and surface bombardment that removes material layer ...

  • Treatment and Disposal of Air Pollution Control Residue

    What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic ...

  • Guide To Coolant In Oil Test Methods

    Liquid cooled engines and rotating equipment use glycol based coolants because of their excellent heat transfer abilities. However, glycol based coolants are not desirable at all in lubrication oil itself – Coolant ingression to the lubricant is a particularly nasty contaminant for the variety of damage it can cause. Glycol coolants break down in the high temperature engine environment, ...

  • Optimization of atmospheric air plasma for degradation of organic dyes in wastewater

    This study optimises the degradation of a cocktail of the dyes methyl orange and bromothymol blue by atmospheric air plasma. Response surface methodology (RSM) was employed to investigate the efficacy of the plasma process parameters on degradation efficiency. A Box–Behnken design (BBD) was employed to optimise the degradation of dyes by air plasma discharge. A second order polynomial equation ...

  • Is it time to recycle more nickel?

    Now you might think me a little sad, but I have to confess that as a metallurgist, I always find it interesting just how closely the history of mankind is linked to advances in metal working. The first evidence of metal working in Europe dates from around 5500 BC with the extraction of copper, lead and precious metals and this was followed by the working of bronze from around 4000 BC, both of ...

  • Nuclear Waste: Greatest environmental challenge facing society

    Dr Tim Johnson discusses how we can tackle the nuclear waste epidemic. A world full of waste They say you can tell a lot about a society by what it throws away. Like me, I’m sure you can recall the excitement of archaeologists on numerous TV documentaries, sifting through the remains of a rubbish dump or ‘midden’ on the edge of some ...

  • Let’s talk plasma

    Usually when I attend a conference on behalf of Tetronics I am about the average age of the other delegates. Not this time. Suddenly, I am old enough to be the father of most of the other people here, because this is a university-based conference hosted by the University of Liverpool. Yes, this is the snappily-titled International Workshop on Plasmas for Energy and Environmental Applications, or ...

  • 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 ...
