BRASS-COLORED COATING WITH COLOR-IMPARTING NITRIDE LAYER

摘要

In a process for producing a brass-colored coating for fixtures, hardware, and articles in daily use, application of an intermediate layer to the substrate or to a base coating on the substrate is made by spraying, for which purpose a magnetron source with a zirconium target is situated in the process chamber in the proximity to the substrate and a mixture of argon and nitrogen serves as process gas, and the application of the top layer by spraying is done using a zirconium target in a mixture of argon and oxygen as process gas wherein the top layer is modified by bombardment with low-energy ions in a mixture of argon as carrier gas and a reactive gas, for example oxygen or hydrogen.
