90% of hydraulic cylinder failure is a result of inferior piston rod coatings. But with Griekspoor, you’re protected. TOPCOAT are the highest quality coatings available — maximizing the lifespan of equipment in the world’s most challenging conditions.
Our coatings are extremely wear-resistant and corrosion-resistant, that is finished to the specified fit and roughness. We coat products up to a length of 23 meters, a diameter of 1100 millimeters and a weight of 20 tonnes.
All TOPCOAT coatings meet the demands of the latest version of the NBD 10300, the coating specification for (ceramic) coatings developed and used by the Dutch department of waterways.
The coating consists of a plasma-sprayed nickel-chrome adhesive layer with a minimum thickness of 100μm and an aluminium oxide/titanium oxide ceramic top layer.
This coating is similar to TOPCOAT®, however the plasa sprayed nickel-chrome based adhesive layer is replaced by an HVOF sprayed nickel based superalloy (TOPCOAT 177).
This ceramic coating is mainly used where a very high degree of chemical resistance against strong acids or bases is required. The coating is tribologically similar to the standard TOPCOAT. The colour is dark grey/green.
This coating is similar to TOPCOAT ULTRA, however the plasma sprayed nickel-chrome based adhesive layer is replaced by an HVOF sprayed nickel based superalloy (TOPCOAT 177).
TOPCOAT CCR is especially developed as a better alternative to electrolytically applied (nickel-) chromium. A major advantage is that no 6-valent chromium is formed during production.
TOPCOAT CCR+ consists of a TOPCOAT 177 UHCR (nickel based superalloy) HVOF sprayed intermediate coating and a chromium carbide top coating, namely TOPCOAT CCR.
TOPCOAT WCR (tungsten carbide) coating is especially developed as a hard chrome replacement, a better alternative to electrolytically applied (nickel-)chromium, when extreme wear resistance is required.
WCR+ is more resistant to corrosion than (nickel-)chromium, especially in sodium chloride, acidic, and alkaline environments.
TOPCOAT 177 UHCR (Ultra High Corrosion Resistant) is an in house developed intermediate coating. This nickel based superalloy's main purpose is to attain optimum corrosion resistance in highly chemical environments with high temperatures.
TOPCOAT 107 is the economic alternative for nickel chrome plating. Even though the costs of both alloys are similar, the corrosion resistance and wear resistance for TOPCOAT 107 are significantly better than for nickel chrome.
TOPCOAT 107+ an absolute top coating system consisting of a super alloy intermediate coating and a special blended carbide top coating. Both coatings are a Griekspoor, in house development, developed in cooperation with Dutch top corrosions experts.
