Physical Vapour Deposition process
PVD technology developed by Vacuum Surtec consists in
surface treatment with ceramic compounds characterised as follows:
- high levels of hardness (2000 ÷ 3000 HV);
- chemical stability (UV stability according to UNI 9397 standard);
- friction coefficient variation on the sublayer;
- non-toxic and biocompatibility levels (according to ISO 10993-10 standard);
- surface reproducibility;
- base surface roughness preservation;
- increased resistance to wear and corrosion (according to ISO 9227, ASTMB117 and DIN50021 standards);
- exceptional resistance to the action of many aggressive domestic and industrial products and solvents according to MKF testing;
- vast range of colours: gold-yellow, brass-yellow, steel grey, pearl grey, gunbarrel grey, black, copper, bronze, blue, green, etc.
The materials suitable for PVD coating are metals (including precious metals), charged plastic, glass and ceramics.
