Abstract
Coating (1) for a substrate (100) made of plastic or metal material, comprising at least one first layer (10) made of metal material or metal compound, and at least one second layer (11) made of metal material or metal compound, wherein said first layer (11) is deposited by cathodic sputtering on said substrate (100) and wherein said first layer (11) is made of a material having elasticity modulus of less than 150 Gpa, preferably less than 125 Gpa, and said second layer (12) is deposited by cathodic sputtering on said first layer (10) and wherein said second layer (11) is made of a material or having hardness greater than 600 Vickers.
