Zusammenfassung:	PCT No. PCT/FR92/00969 Sec. 371 Date Jul. 19, 1993 Sec. 102(e) Date Jul. 19, 1993 PCT Filed Oct. 14, 1992 PCT Pub. No. WO93/08316 PCT Pub. Date Apr. 29, 1993The present invention relates to a multilayer material more particularly intended for producing an anti-erosion and anti-abrasion coating, as well as the process for producing this multilayer material. The aim of the invention is to produce a material which has a greater resistance and which can be deposited at low temperatures. This aim is achieved with the aid of a multilayer material, which is characterized in that it 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 among carbon or nitrogen or a mixture of carbon and nitrogen in tungsten or a tungsten alloy, the two types of layers are alternating. The invention more particularly relates to the production of a coating for parts used in aeronautics.
