METHOD FOR SMOOTHING THE SURFACE OF A PART MADE FROM A CMC MATERIAL |
| 摘要 |
<p>The invention relates to a method for smoothing a corrugated, rough surface of a part made from a ceramic matrix composite material. According to the invention, a ceramic coating is formed on the surface of the part by means of the following steps, namely: application (20) of a liquid composition on the surface of the part, said composition containing a ceramic precursor polymer and a solid refractory filler; crosslinking (40) of the polymer; and conversion (50) of the crosslinked polymer into ceramic by means of heat treatment. The method also includes the impregnation of the ceramic coating with a liquid metal composition (60).</p> |
