Estimating the term…
The present invention relates to a multilayer material useful as an anti-erosion and anti-abrasion coating, and to a process for producing the multilayer material at low temperatures. The multilayer material comprises a substrate covered with at least one metallic tungsten ductile layer and at least one hard layer of a solid solution of an additional element chosen from carbon or nitrogen or a mixture of carbon and nitrogen in tungsten or a tungsten alloy, the two types of layers ar alternating. The multilayer material is particularly useful as a coating for parts used in aeronautics.
A multilayer material, characterized in that it comprises a substrate covered with at least one ductile, metallic tungsten or tungsten alloy layer and at least one hard layer of a solid solution of nitrogen, in tungsten or in a tungsten alloy, the two types of layers alternating.
