Abstract
The invention concerns a process for coating a substrate 1 of little or no corrosion resistance, especially a metal substrate having an alloy consisting at least of Ni, Cr and Fe, in an evacuable coating chamber 15, 15a. It comprises making an electrode that can be connected to a current supply 10, this electrode being electrically connected to a target 3 which is sputtered and the sputtered particles of which are deposited on the substrate 1. Reactive process gases are, for this purpose, supplied to the coating chamber 15, 15a, so that an amorphously depositing layer 2 is applied onto the substrate.
