The Stategic Unit Coatings is your partner for chemical nickel and zinc phosphate coatings, as well as a combination of both. We offer highest quality and reliability for optimal protection of your steel components against wear and corrosion. It is possible to coat single batches as well as to support large series from development to ongoing production.
Chemical nickel plating of your components
TAILORCOAT® ENiP is a nickel-phosphorus alloy that is deposited on workpieces without current true to contour, even on workpieces with complex geometries.
It offers excellent wear and corrosion resistance. TAILORCOAT® ENiP Mid-P has a phosphorus content of 6 - 9 wt%.This high phosphorus content makes the coating ductile, corrosion-resistant and offers pressure resistance. With heat treatment a recrystallization of the nickel phosphides is possible whereby the hardness of nickel phosphorus increases and results in an improved wear protection
Zinc phosphating of your components
ZnPh coatings on carbon steels and spring steels improve the tribological properties e.g. of clutch plates. Due to the improved tribological properties, stick-slip effects are avoided and seizure and fretting corrosion are prevented.
Zinc-phosphate surfaces prevent from corrosion and are used as a primer for sliding laquers. Zinc-phosphate serves as a lubricant with antiabrasive effect, e.g., for better machining in non-cutting forming processes such as drawing and pressing.
TAILORCOAT® coatings are chemical, electroless platings. When the components are dipped into the solution, the previously defined layer is applied by chemical reactions of the metallic surfaces. Depending on the requirements, the layer thickness or the phosphorus content during the chemical nickel plating can be adjusted. Partial coating is also possible using certain processes.
Our coating process is designed for rack goods and the max. dimensions are 900/600/700 mm.
TAILORCOAT® coatings from the Strategic Unit Coatings can be applied to carbon steel and low-alloy steels and are often used in the automotive, commercial vehicle and mechanical engineering industries, but we are also happy to serve other industries.
As a certified partner of the automotive industry, we can recommend our coatings for the following applications, among others:
TAILORCOAT® ENiP: gear flanges, wheel hubs, ring sockets and ring nipples, axial and thrust washers, housings, pistons, valve pistons and in particular the partial hard nickel plating of coupling hubs
TAILORCOAT® ZnPh: clutch disks, clutch springs, hydraulic lines and generally components with stable coefficients of friction
