【摘要】 研究了PCVD法在电工钢上沉积Si的规律及其电磁性能，探讨了处理温度对表层中硅含量的影响。本底Si含量0．5％；厚0.15mm的电工钢经PCVD处理后磁性能得到极大改善，高温扩散后其铁损P_10／50下降了55％，P_15／50下降了66.2％，磁感应强度B₅₀₀₀提高了5．42％。更多还原

【Abstract】 This paper deals with PCVD Si - deposited layetof silicon steel sheets and its electromagnetic properties.The influence of treating temperature on the layer is stud-ied. The properties of the treared sheets are improved.After diffusing at 1150℃ the core loss of the sheets treat-ed by PCVD Si - deposition reduces more about 55 % andtheir flux density increases 5. 42 %.更多还原
