DEMARTIN Chrome Boost LF
Chrom Boost LF: pearl chrome coating with dry-lubricating topcoat
Chrom Boost LF is an innovative coating solution that combines a high-performance pearl chrome coating with a dry-lubricating topcoat. This unique combination offers improved wear resistance, corrosion resistance and friction minimisation for demanding industrial applications
The basis is a hard chrome coating with a special bead structure (1). This structure gives the surface greater hardness and wear resistance compared to conventional chrome coatings. The pearl structure also enables better adhesion of the topcoat (2) and improves the durability of the coating.
The dry lubricating topcoat (2) is a special coating that is applied to the pearl chrome layer. This topcoat contains solid lubricants that have a friction-minimising effect. This reduces or even eliminates the need for liquid lubricants, resulting in a significant reduction in friction and wear.
The combination of pearl chrome and dry lubricating topcoat makes Chromium Boost LF a versatile solution for various industrial sectors. The coating is particularly suitable for applications involving high loads, abrasive wear and adverse environmental conditions. Examples include hydraulic cylinders, piston rods, valves, pumps and transmission components.
A key benefit of Chrom Boost LF is the extension of the service life of components. The improved wear protection and friction minimisation reduce downtimes and extend maintenance intervals. This leads to increased productivity and cost efficiency in industrial processes.
Chrome Boost LF is applied using a special coating process. Firstly, the hard chrome coating with the bead structure is applied to the component by electroplating. The dry-lubricating topcoat is then applied using a spraying process or dip coating. Precise control of the process parameters ensures a uniform and adhesive coating is achieved.
Overall, Chrom Boost LF is an advanced coating solution that combines the advantages of pearl chrome and dry lubricating topcoats. By combining improved tribological properties, corrosion resistance and durability, this coating offers high added value for demanding industrial applications. With Chrom Boost LF, companies can increase their productivity, reduce costs and optimise the performance of their components.
