A process for coating a thermally resistant substrate with first and second materials selected respectively from a first group consisting of TiN, TaN, ZrN and HfN, and from a second group consisting of Au and an alloy of Au, comprising the first step of depositing on said substrate a non-opaque layer consisting essentially of one of said first or second materials, the second step of depositing on said layer of one of said first or second materials a non-opaque layer consisting essentially of the other of said materials, the third step of depositing on said layer of said other of said materials another non-opaque layer consisting essentially of said one of said first or second materials, and repeating each of said second and third steps at least once, the layers of said first material having a thickness in the range of 0.01 micrometers to 0.33 micrometers, and the layers of said second material having a thickness in the range of 0.003 micrometers to 0.13 micrometers.
