1. A method for preventing gases and fluids to penetrate a surface of an object, comprising the steps of:
- depositing (S1) an amorphous metal (5) on a surface of an object (4), wherein the depositing comprises;
depositing a first amorphous metal on said surface of said object forming a continuous layer (5a) thereon; and
depositing a second amorphous metal on the continuous layer formed by the first amorphous metal forming a continuous layer (5b) thereon, wherein the composition of said second amorphous metal differs from the composition of said first amorphous metal;
forming (S2) a continuous layer of said amorphous metal (5) on said surface of said object (4);
binding (S3) said amorphous metal (5) to said surface of said object by chemical binding; and
passivation (S4) of a surface of said amorphous metal (5) facing away from said surface of said object (4).

8. A membrane (4), characterized in that a surface thereof is covered with a layer of an amorphous metal (5) wherein the layer of amorphous metal comprises a first layer having a first composition and a second layer having a second composition, wherein the two compositions differ from each other, and
wherein said amorphous metal is chemically bound to said surface of said membrane and wherein said layer comprises a passive surface facing away from said surface of said membrane.
