一般软磁硅钢含硅量小于 3 5 % ,超过此限则难于加工。为了提高硅钢的磁性 ,除通过冷轧提高硅钢织构度外 ,最有效的方法是提高钢片硅含量 ,达 6 5 %Si为最佳。由于超过 3 5 %Si含量的钢 ,无法轧制成薄片。为此用等离子体化学气相沉积方法 (thePlasmaEnhancedChemicalVaporDeposition) ,在 0 1～ 0 3mm厚的普通硅钢片表面涂硅 ,再进行短时间高温扩散 ,使硅钢平均含硅量可达 6 5 % ,磁性能超过或达到冷轧取向硅钢水平 General soft magnetic silicon content of less than 35% silicon, more than this limit is difficult to process. In order to improve the magnetic properties of silicon steel, in addition to improving the texture of silicon steel by cold rolling, the most effective way is to increase the silicon content of the steel sheet to 65% Si. Due to more than 35% Si content of steel, can not be rolled into flakes. To do this, the plasma enhanced chemical vapor deposition (PACS) method is used to apply silicon on the surface of ordinary silicon steel sheets of 0 1 ~ 0 3mm thick and then diffuse for a short time so that the average silicon content of silicon steel can reach 65% Or cold-rolled oriented silicon steel level
