VD0608 Chrom-Nickel (Cr/Ni)-vapour deposition materials

Description

Chromium-Nickel evaporation materials typically have a high melting point. They can withstand the high temperatures required for evaporation processes without significant decomposition. This ensures stable evaporation and a consistent deposition rate. The Chromium and Nickel components in these materials contribute to their corrosion resistance. They resist attack by various corrosive agents and are suitable for use in environments where corrosion is a concern. Chromium-Nickel deposition materials demonstrate good adhesion on various substrates so that the deposited layers remain securely attached to the underlying surface. This adhesion property is critical for producing coatings that are durable and long-lasting. These materials produce smooth and uniform coatings during evaporation, which results in thin films with maintained optical, electrical and mechanical characteristics given that the coatings are free from defects and contaminants. Chromium-Nickel deposition materials generally exhibit adequate electrical conductivity and are therefore appropriate for applications where electrical performance is critical. These materials also show good thermal stability and retain their properties at elevated temperatures. Consequently, they can be utilised in processes that involve significant thermal loads.
