Castolin unveils HD8 extreme wear-resistant coating for highly demanding industries

(PresseBox) (Schweiz, ) HD8 is an extremely wear-resistant coating made with an innovative, high-deposition welding technique. This coating has been specifically developed by our engineers in Wiener Neudorf (Austria) who aimed to get a very high density of tungsten carbides homogeneously distributed within a nickel-based matrix at high deposition rates. The critical parameters of the process, in particular the temperature, are automatically controlled in order to avoid severe carbide dissolution as it may happen in standard welding techniques. Furthermore, the coating is optimized with a low dilution and consequently the overlay chemistry is not negatively affected by the base material. The wear resistance is far superior than steel hardened plates or usual chromium carbide wearplates as it is measured with ASTM G65 test.

Ideal for extremely demanding applications in cement and mining industries

With its extreme wear-resistance, smooth and regular surface HD8 is the ideal solution for applications where standard chromium carbides wearplates are too heavy and not resistant enough, in particular where large production throughput is required. For instance, expensive heavy duty fans are exposed to extreme erosion and have to be regularly replaced. HD8 increases service life and consequently reduces the costs associated to new parts and changeovers in high demanding industries such as for instance cement, mining and power generation. Plates and customized HD8 parts are provided exclusively by CastoLab® Services workshops. HD8 can be applied directly on the customers' parts or provided as full plates.

Wear-resistance optimization

In order to provide the optimum wear-resistance, the Castolin automated changeover system allows producing on the same surface continuous beads of different alloys. This ensures a smooth and regular surface which is critical in high demanding applications. Consequently, the area that is exposed to the highest wear can be coated with HD8, while an iron-based powder can be deposited where the wear phenomena is not severe. This optimizes the part service life and offers the best cost-efficient solution.
