DURALLOY® is an extremely hard, crack-free, precise, very thin and ultrapure metallic chromium layer.
A nodular structured surface can be deposited in the layer thickness range from 1.5 to 20 μm. Due to the low process temperature of under 70 °C no changes to the structure of the base material occur during plating. This essential advantage of the process ensures shape and hardness stability for any manufactured components. DURALLOY® provides effective protection against friction and vibration corrosion and thus increases considerably the wear resistance of the material when used, for example, in gears or with shaft-hub-joints. The nodular structured surface of the DURALLOY® layer provides outstanding chemical resistance and material hardness for applications where conventional coating systems with comparable layer thicknesses are ineffective.
Continuous and homogeneous transitions in the microstructure, without any sharp edges, enables oil to be retained in the surface. Additional layers can be applied either to improve the dry-running properties or to satisfy other specific requirements
