For the boffins, this process includes stripping of the existing chrome, performing a stress relief bake followed by a glass bead blast. The rockers are then polished and a proprietary activation of the base material is performed. Only then are the parts chrome plated to a specified thickness, achieving the maximum hardness of 850-100Hv (65-70Rc). They are then post-baked for hydrogen embrittlement relief.
