A PROCESS FOR PREPARATION OF NANO CERAMIC-METAL MATRIX COMPOSITES AND APPARATUS THEREOF |
摘要 |
<p>A method to introduce ceramic particles into the liquid metal from the polymeric pre¬ cursor route by in-situ process by cross-linking organic precursor into a hard polymer, this powder is crushed, and then added to the liquid melt for in-situ pyrolysis of the organic into the ceramic phase. The starting material, the organic, for the above process can be in the form of a liquid or a solid. If it is a solid it us usually dissolved into a solvent to create a liquid form. The organic is then cross linked either directly by a thermal process, by adding a catalyst, or by the well known sol-gel process into a hard polymer. It is this hard polymer which is then pyrolyzed into the high temperature ceramic material by the process outlined above.</p> |
