HVAF and TWI
TWI is planning to install Kermetico HVAF equipment at our Cambridge facility to provide independent assessment of the HVAF technology against competing technologies, such as traditional hard chrome plating replacement alternatives, across a wide range of industrial applications. This facility will be unique in the UK and available for the benefit of TWI Members.
Michael Breitsameter, Director of Sales and Marketing at Kermetico, with over 30 years’ experience in the thermal spraying industry, had this to say on this new collaboration:
“Kermetico is very much looking forward to working with TWI, largely based on its outstanding reputation for supporting a range of industries, the team of experienced individuals who we have been interacting with, but also some personal memories of working with this group back in the 1990s. This was a formative time for HVOF with the Top Gun, the Diamond Jet and the JP5000 HVOF systems being adopted by TWI, two of which I was personally involved with. TWI established a position as the UK's leading independent surface technology research house, utilising cutting edge equipment and resources to push the boundaries, to outreach to new industry spaces, along with conducting high quality research. My role was always to promote and sell the technology, usually to update existing technology, adding capability or capacity at commercial companies selling coatings to a range of industries.
“On one occasion I sent a potential equipment client (the owner of a highly respected spray shop) to TWI to have the JP5000 demonstrated, based on their level of comfort in the fact that TWI had no specific agenda regarding one piece of equipment or another, one technology or another. This type of outreach to industry is a role that TWI fulfils for the good of its Membership and to ensure the latest technologies are available to industry, without bias, leveraging the many years of experience accumulated in this area.”
Dave Harvey, TWI’s Technology Fellow in Surface Engineering, also spoke on the process, saying:
“TWI has been at the forefront of the evaluation of novel thermal spraying processes including HVOF and cold spraying for 30 years. HVAF spraying is one of the most important technology developments in this field in recent years, bridging the gap between the HVOF and cold spray processes. HVAF has the potential to deliver benefits to coating vendors and end-users in terms of reduced coating material costs, higher productivity and longer service life in demanding service conditions, whilst complying with environmental legislation. We really look forward to working with the Kermetico HVAF system and providing TWI Members with an independent evaluation of the characteristics and performance of coatings produced by this exciting technology.”
To support this activity, TWI is launching a Joint Industry Project on New Surface Engineering topics, comparing HVAF technology with the extreme high-speed laser application (EHLA) technology, and conventional HVOF hard chrome plating replacement technologies.
Further R&D support may be accessed by Members through TWI’s core research programme, single client projects and collaborative programmes. To discuss your requirements in more detail please contact us, below.
