Method for coating ceramic discs and ceramic disc obtained by said method |
摘要 |
<p>The method includes the phases of preparation of said ceramic discs once lapped and polished; and deposition of a layer of hydrogenated amorphous carbon (or DLC: Diamond-Like Carbon) on said ceramic discs, said deposition phase including the following stages: exposure of said ceramic discs to vacuum; application of a cleaning plasma on said ceramic discs; application of a first deposition plasma on said ceramic discs; and application of a second deposition plasma on said ceramic discs. The ceramic disc is characterised in that it includes a layer of hydrogenated amorphous carbon deposited directly onto the ceramic disc. Thereby are obtained ceramic discs for utilisation in mixer valves of single-lever mixer type whose friction coefficient is lower that that of the ceramic discs currently used, all this without loss of leak tightness, without having to use grease and with a low manufacturing cost.</p> |
