<p>The Cr2O3 protective coating (3) is applied, during the vacuum spray process, as a leakproof coating to a support (1), and has a density of not more than 5.3 g/cm3, a residual porosity of less than 2%, a Vickers hardness (HV) of over 2000 kp/mmm2 and an electric strength of at least 5 V/ mu m of protective thickness; it is particularly suited as a protective coating on supports (3) exposed to corrosion and simultaneously subjected to high mechanical loads.</p> |
