To meet growing demands, increasing production speeds push tools to the limit, resulting either in damaging or wearing parts that conclude in lost productivity, expensive downtime and pay-outs. By using our low friction coatings, at Refmet Ceramics, we aim to alleviate these problems enhancing tools and component performance.

Our low friction coatings aim to dramatically reduce downtime and expenditure be extending the lifetime of components and tools, optimising performance. Out performing a vast range of industry standard treatments that include chromium nitride, titanium nitride and plasma deposited thick film ceramics, our low friction coatings are an ideal solution to a host of wear and friction problems.

Our coatings are used on a vast range of applications that include:

  • Metal forming
  • Vacuum
  • Plastic injection
  • Metal forming
  • Motorsport
  • Aerospace
  • Medical

Wear Resistant Coatings

At Refmet Ceramics, we are always looking for ways to innovate in wear resistant coatings, using advanced materials to extend the performance and lifetime of tools and components. Our wear resistant coatings are able to address the issues related to various wear, frictional forces and chemical affinities, utilising various properties that include super low friction, immense hardness and specific surface chemistries.

Thanks to our resistant coatings, previously thought impossible to coat components are now able to be layered using leading edge technologies. With each application facing its own unique challenges with trying to push the boundaries of performance, our wear resistant coatings are able to assist in achieving these goals.   

Coating Applications

Our coating applications are cost effective solutions to boost components and tool performance, improving output, reducing downtime and maintaining consistent levels of quality. Compared to the cost of replacing tools and components, which can cost hundreds of pounds, the cost of coating applications can be easily recuperated through the improved performance of the application and eliminating the need to frequently replace the part.

Our coatings are regularly utilised on a number of applications that include:

  • Bearings
  • Blades
  • Fasteners
  • Gears
  • Threads
  • Stamping tools
  • Plastic injection
  • Lead screws

If you have a tool or component that is unique to your process, please contact us to see how we can assist in enhancing its performance. 

Solid Lubrication Film

Offering the latest in low friction properties, solid lubrication film takes surface engineering to new levels of precision and is unrivalled by any commercial coating process available. Solid lubrication film offers exceptional low friction of 0.03µ – 0.07µ (dynamic/static), avoiding metal to metal contact and keeping both friction and drag to an absolute minimum.

With the ability to be deposited to half a micron thick and a temperature less than 50°C, ensures that the contours of the application are followed without thermal impact and distortion. With such high levels of precision, no excess coating build up is created, allowing solid lubrication film to be applied to a number of materials that include:

  • Nickel
  • Aluminium
  • Electroless nickel
  • Tool steels
  • Stainless steels
  • Copper and brass
  • Diamond-like carbon (DLC)

Due to its amazing high load capacity and chemical stability, solid lubrication film offers exceptional coating possibilities, enhancing the performance of tools and components.
 

Advanced Composite Structure

Advanced Composite Structure is a new generation of thin film vapour, meeting the demands of tribological challenges with the ability to adapt its functional properties. Delivering more than one specific property, Advanced Composite Structure offers hardness levels up to 4,000HV, a friction base of 0.05µ and a thickness of 2–10µm.

Our Advanced Composite Structure is an ideal choice for alleviating adhesive wear coursed by metal on metal contact, making it the perfect choice for metal stamping and forming. Other benefits include providing consistent lower tooling and maintenance costs through increasing tool life cycles and tool performance.  

Synthetic Diamond Film

Synthetic Diamond Film significantly increases the surface hardness of a tool or component taking the surface of a typical 60 HRC hardened tool steel (740 HV) to a micro-hardness level up to 4,000 HV - a magnitude some five times the hardness of the original substrate. Synthetic Diamond Film can be applied precisely and smooth to a thickness of 2–3µm, with an exceptionally low friction of <0.1µ, reducing drag and minimising operational temperatures. This also allows for polished surfaces to remain intact, conforming to both the surface finish and substrate contours.

Synthetic Diamond Film is ideal for temperature sensitive materials, with a deposition temperature of less than 200°C, not risking thermal distortion, substrate hardness or heat treatment presses. Because of diamond's resistant properties, our film creates a corrosion resistant barrier making it suitable for industrial components and medical devices.

Reaction Processed Ceramic

Whereas solid ceramics offer high temperature and hardness properties, the limits to its forming can make a structure brittle and increase costs, Reaction Processed Ceramic (RPC) bridges this gap, allowing components and tools to be coated with pure ceramics material creating a strong, durable structure. Reaction Processed Ceramic protects coated surfaces from the extreme corrosion and wear when subject to high temperatures, unlike other monolithic ceramic bodies. This allows the ceramic to perform under temperatures in excess of 700°C, protecting the structure from loss of hardness and oxidation.

Other benefits of Reaction Processed Ceramic include its hardness of 2,850 HV, 4 times harder than tool steel, and its thick 75µm coating, improving the wear and performance of tools and components. This makes it ideal for a wide range of applications.
