Abstract:
1. A method of forming an opaque chrome coating on a substrate, comprising: providing a substrate and depositing an opaque chrome coating having three layers on said substrate, said deposition being: depositing an initial chrome layer having a thickness less than 10 nm on the substrate without ion-assist or with undetectable ion-assist; and depositing one of the remaining layers of the opaque chrome coating with or without ion-assist and depositing the other one of the remaining layers of the opaque chrome coating with ion-assist to thereby form an opaque chrome coating having three layers on said substrate; wherein ion-assist is defined as undetectable when the ion energies are less than or equal to about 25 V and current density is less than or equal to about 0.04 mA/cm
