TRD Surfaces

TRD Surfaces delivers cutting-edge surface solutions to steel and stainless steel parts. We supply the industry with coating services and engineering parts:

TRD Diffusion coatings

Our chromium-based diffusion coatings are used for increasing wear and corrosion resistance of steel components. Typical parts include valves, nozzles and other complex parts.

TRD Anti-Slip

TRD Anti-Slip is a unique surface solution that offers great mechanical interlocking and increase holding forces more than fourfold. Typical applications are within workholding, automation, robotics, material handling, and mechanical design.

Recent news



TRD CrC now withstanding 100.000 tons

Last year we showed how our TRD Chromium Carbide surfaces increase the lifetime of extruder dies. The dies are still in use, and the total amount of feedstock processed is now an astonishing 100.000 tons, still delivering the same, high end-product quality.

If you are in the extruder processing industry, let us help you improve your tool economy, end-product quality and process stability.

Anti-Slip Elements (ASE)

TRD Surfaces introduces a new range of Anti-Slip Elements for safer and more reliable interfaces. The static friction is more than quadrupled with the anti-slip components and 4x shear forces can be handled. The first set of elements were developed for reliable high friction rings for MAN Energy Solutions.

Article in Motorship

The magazine “The Motorship” has interviewed MAN Energy Solutions about the fruitful collaboration between TRD Surfaces, Heriott-Watt University in Scotland and MAN. The collaboration has successfully resulted in a new, high standard for a safety component employed by MAN in their two-stroke marine engines. TRD Surfaces is now the exclusive, global supplier of high-friction rings for MAN.

High performance nozzles

One of the strengths of the TRD technology is the ability to treat the smallest holes and cavities equal to the rest of the part.

This is essential when coating the inside of a nozzle. Combined with the ceramic hardness of TRD (up to 2000 HV) and the extreme corrosion resistance (up to duplex standard), TRD diffusion coatings are ideal for nozzles.

Many of the parts we receive are nozzles, especially made of stainless steel 1.4404 and 1.4305. Both are industry standards for nozzles.

If your nozzles are dealing with too short a lifetime and declining performance, give us a call and we’ll handle your challenges.



Preventing wear and material loss during food processing

Our ceramic TRD Chromium Carbide (CrC) surface treatment is now approved as a food contact material. This surface solution is suitable for all types of tool steels used in harsh and abrasive environments in the food processing industry.

The high hardness of the ceramic TRD CrC (2000 HV) greatly reduces the amount of wear. This means longer lifetime of the machinery, and of course, minimizes the amount of material transfered to the processed food.

For the compliance test, not even the slightest trace of coating material was detected in the processed media.



Enhancing AISI 316L to a Super Duplex grade

How is it possible to turn an AISI 316L stainless steel into a Super Duplex stainless steel?

Here at TRD we have engineered a surface treatment that is tailored specifically for austenitic stainless steel. The surface treatment significantly improves corrosion resistance by diffusion of chromium.

The illustration below shows that our TRD GammaX is as corrosion resistant as a Super Duplex stainless steel, grade 1.4410.



Laser technology to achieve controllable friction

Today, we are excited to announce our new technology L-TRD developed together with MAN ES: Lasertexturing of steel surfaces combined with subsequent TRD hardening.

Laser texturing enables a precise surface manipulation, while TRD hardening is the only viable method for subsequent hardening of the laser-melted surface. The end result is a highly defined topography which is built to last and has a reproducible static coefficient of friction. L-TRD is three times as precise as the former solution chosen by MAN ES for one of their high friction components.

If you have an application where controlled friction is vital, please let us help you solve your challenge.

TRD approved as food contact material

In order to meet the growing demand within food processing industry, our TRD surface treatments for stainless steel is now tested and approved according to all current regulations.

As expected, no elements from the base material nor the coating has been found to migrate to the test medium, once again proving the superior corrosion resistance of TRD.

TRD withstanding 30.000 tons of aqua feed

We are happy to share these recent results from an industrial manufacturer of fish feed pellets. Our dies (the tool at the end of an extruder) have shown to have a lifetime more than 3X compared to conventional solutions, while at the same time improving pellet quality and extruder efficiency.

The dies are designed and offered together with GRAINTEC A/S, and we look forward to many more solutions being offered to end-users.
