COATED LIGHTWEIGHT METAL DISK

摘要

The invention relates to a coated lightweight metal disk, in particular a brake disk, comprising a support disk made of a thermally resistant lightweight metal alloy, and a heat-insulating friction layer formed from a metal alloy that includes nanocrystals. The friction layer can be applied directly to the support disk without adding an insulating intermediate layer. Because of the thermally insulating effect of the friction layer, only a moderate amount of heat is transferred to the support disk.
