** Thicker bond coat equals better corrosion resistance.

*** Thicker if necessary (on request)

 

TOPCOAT® Ceramic coating (TC)

TOPCOAT® ceramic coating (TC)

TOPCOAT® Our 'standard' TOPCOAT® is our earliest developed coating and is applied since 1987. For a number of years this was the only coating that could be supplied for hydraulic applications. (They can choose any colour as long as it is black).…
TOPCOAT® ULTRA Ceramic coating (TCU)

TOPCOAT® ULTRA ceramic coating (TCU)

TOPCOAT® Ultra 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. The coating…
TOPCOAT®+ Ceramic coating (TC+)

TOPCOAT®+ ceramic coating (TC+)

TOPCOAT®+ This coating is similar to TOPCOAT® ceramics, however the plasa sprayed nickel-chrome based adhesive layer is replaced by an HVOF sprayed nickel based superalloy (TOPCOAT® 177). As a result the corrosion resistance, chemical resistance,…
TOPCOAT® ULTRA + Ceramic coating (TCU+)

TOPCOAT® ULTRA + ceramic coating (TCU+)

TOPCOAT® Ultra+ 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). As a result the corrosion resistance and resulting…
TOPCOAT® CCR, Chromium Carbide metallic HVOF coating

TOPCOAT® CCR, Chromium Carbide metallic HVOF coating

TOPCOAT® CCR TOPCOAT® CCR is especially developed as a better alternative to electrolytically applied (nickel-)chromium. It is a single layer chromium carbide. A major advantage is that no 6-valent chromium is formed during production. There are…
TOPCOAT® CCR+, Chromium Carbide metallic HVOF coating

TOPCOAT® CCR+, Chromium Carbide metallic HVOF coating

TOPCOAT® CCR+ TOPCOAT® CCR+ consists of a TOPCOAT® 177 UHCR (nickel based superalloy) HVOF sprayed intermediate coating and a chromium carbide top coating, namely TOPCOAT® CCR. As a result the corrosion resistance and therefore the operational…
TOPCOAT® WCR, Tungsten Carbide metallic HVOF coating

TOPCOAT® WCR, tungsten carbide metallic HVOF coating

TOPCOAT® WCR 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. A major advantage is that no…
TOPCOAT® WCR+, Tungsten Carbide metallic HVOF coating

TOPCOAT® WCR+, Tungsten Carbide metallic HVOF coating

TOPCOAT® WCR+ TOPCOAT® WCR+ consists of a TOPCOAT® 177 UHCR intermediate coating, a nickel based superalloy, and a tungsten carbide top coating, namely TOPCOAT® WCR. As a result corrosion resistance and operational reliability are improved while…
TOPCOAT® 177

TOPCOAT® 177

TOPCOAT® 177 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…
TOPCOAT ® 107

TOPCOAT® 107

TOPCOAT® 107 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. TOPCOAT® 107…
