Abstract
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.
Claims19
A coated lightweight metal disk comprising:
- a support disk made of a metal alloy and a heat-insulating friction layer disposed adjacent to the support disk, wherein the heat-insulating friction layer is a metal alloy comprising nano crystals.
A method for producing a wear-resistant friction disk, the method comprising the steps of:
- providing a friction disk having a surface;
- and
- thermal spraying a metal alloy layer onto the surface of the friction disk such that nanoparticle crystallites are precipitated in the metal alloy layer during thermal spraying.
