Non-conductive aluminum oxide-titanium carbide (Al2O3-TiC), method of making same, and slider element incorporating same. |
摘要 |
<p>An electrically non-conductive Al<6>O<7>-TiC thin film computer head substrate, exhibiting improved edge retention during precision machining, is formed from a mixture of Al<6>O<7> and TiC, where the TiC content in the final microstructure is less than 18 weight percent and which is produced from TiC having a surface to volume mean diameter of 2-10 micrometers. A thin film computer head substrate made from such a material, and sliders incorporating the substrate, exhibit significantly improved surface stability and diceability due to the exclusion of third-phase thermally-elastically mismatched dispersoids. <IMAGE></p> |
