| Hardness 93-95 Rc - Our surface hardness, as measured on the Knoop scale, is 4700 Kg/mm2 or the equivalent of 93-95 Rc. This means PVD ceramic films provide excellent wear resistance. |
 |
| Chemical Resistance - As a ceramic material, PVD films are inherently inert. Specific formulations of PVD can be made to be highly resistant to gases, harsh chemicals and salts. |
|
| Low Application Temperature - Application of ceramic films by our physical vapor deposition process is accomplished at less than 250°F. This temperature is so low that the drawback of temper or the dimensional distortion accompanying other coating processes do not occur with our PVD applied ceramic films. |
|
| Useful Temperature Range - (-330°F to +2282°F) PVD ceramic films have been used with ball valves handling liquid oxygen at -330ºF with an oxidation threshold of 2282°F. |
|
| Lubricity - PVD Ceramic films have an inherent lubricity that provides static and dynamic coefficient of friction values of <.20 and <.09 respectively. Used in conjunction with lubricants, dynamic coefficient of friction can approach zero when measured to four significant decimal places. |
|
| Uniformity - PVD Ceramic films are sputtered in vacuum at thicknesses ranging from .5 to 6.0 microns (20 to 240 millionths of an inch). Across a flat surface, we have the ability to hold a tolerance of +/- 12 millions of an inch. PVD ceramic films do not build up on inside or outside corners, enabling us to coat razor blades. Surface finishes with features smaller than the thickness of the coating applied tend to be smoothed out. Surface features with an amplitude greater than the thickness of the coating are replicated. |
