Extreme High-Speed Laser Material Deposition (German: EHLA) as technical alternative for certain applications for hard chrome plating
Chromic acid was added to the REACH authorisation list in 2013 and its use requires authorisation in the EU since 2017. Extreme high-speed laser material deposition (German: EHLA) can provide a technical alternative to hard chromium plating, which is particularly suitable for rotationally symmetrical components. The process offers an alternative for applications where increased requirements are made, e.g. on the adhesion of the coating as well as the prevention of corrosion of the coated surface and protection against wear of the treated metal.
