CVD Coating Services

Naxau CVD Chemical Vacuum Vapor Deposition coating services are mainly focused on high hard cutting tools, anti-adhesive/stamping molding and other tooling categories.Naxau CVD can deposit coatings from 5 microns to 20 microns thick, using TiN, TiCN and α-alumina (Al2O3) to form monolayers or multilayers.The CVD deposition process is typically at 900°C or above, with a coating time of 10 hours, and is only for high temperature resistant substrates.

CVD is limited to high-temperature resistant materials, and like PVD coating, the surface of the substrate is smooth and free of oil and rust in order to ensure the bonding of the coating.
