The search for replacement of products with hexavalent chrome, chromium(VI), is an important current issue in today’s market. Griekspoor Thermal Coatings already developed the alternative in 2017: TOPCOAT® 107.

This piston rod is being coated with the economic alternative for nickel chrome plating: TOPCOAT ®107. Watch the video

Griekspoor Thermal Coatings was the first coating specialist who developed its own integrated Linear Positioning Measurement (LPM®) system.

Our recently developed coating TOPCOAT®107 has besides an excellent corrosion- and wear resistance also another big advantage. Small impact damage can easily be repaired by simple welding. For a 90 seconds demonstration see above instruction video.

The photos show the chromium carbide coating before grinding of the lower bearing of a high end screw pump.

It had to wait a little but the coating of the piston rod is finished!

This rod is now pre-machined and is being prepared for the coating process! Follow for update and read more....

In this movie you see one piston rod off a pair. The piston rods are 14.5 meters long each and will settle in a heave compensation cylinder in a large ship.

To assure the delivery time and the projected costs quality of the rod is an essential factor. Therefore in this second article of the the right pre-machining quality, we provide you with a short overview of the quality checkpoints before supplying…

Last week we posted about an 8,5 tons piston rod being prepared for ceramic coating. Click to see the end product!

Griekspoor TC has coated a piston rod with a diameter of 360mm, length 10.500mm, and weight 8,5 tonnes. In the movie you see the rod being prepared for coating.

To really save time (reliable delivery times) and costs for both you as our customer and us as your supplier, pre-machining quality of the rods is an essential factor. Therefor is this article a short overview of the quality checkpoints before…

Follow the process of how to repair the propeller shaft of a ship that has wear damage.

Griekspoor Thermal Coatings has coated 22 Falzspitzen to extend their lifespan. Falzspitzen are cones in a folding machine for leaflets that wear out because of friction.

This piston rod is ready for take off. We applied TOPCOAT®. Prepairing this piston rod with our 'standard' TOPCOAT® makes it suitable for almost all aggressive and corrosive environments.

Yesterday one of the piston rods that will be installed in a ship to harvest in the Dead Sea was coated.

Thermal Coatings will prepare 4 piston rods for a rough and intensive use on a ship that will sail the Dead Sea.

Griekspoor thermal coatings is pleased to carry out their specialization in the coating of very long and thin piston rods. In this case for a foreign gouvernement!

Two unreleased coatings will be tested in our lab! The two rods are ready for an Acetic Acid Salt Spray test(according to ISO 9227 – AASS).

Our colleagues from Griekspoor bv have revised the “Stevensbrug” (Stevens bridge) in Leiden. One of the areas that needed repairing was the cylinder that raises and lowers the bridge. Griekspoor Thermal Coatings removed the damaged chrome plating…

The correct roughness of the piston rod coating is very important in the hydraulic industry. An optimum roughness has a positive effect on the lifespan of the rod coating and on the lifetime of the seals.

Griekspoor Thermal Coatings has recently developed TOPCOAT® 107: a nickel based super alloy blended with carbides. TOPCOAT® 107 is developed as an improved and very economical hard chrome and nickel/chromium replacement.

Laboratory In the laboratory at Griekspoor several devices can be found that are needed to test and improve existing coatings as well as develop new coatings. Griekspoor can test coatings according to a range of standards, e.g. NBD 10300 (corrosion…
