研究了成分及热处理对化学镀ＦｅＭｏＢ非晶态合金镀层交流磁性和结构的影响。讨论了样品在晶化过程中交流磁性和结构的变化。初步解释了样品交流磁性参数随成分的变化规律，同时研究了样品在热处理过程中损耗随退火温度的变化规律。 The effects of composition and heat treatment on AC magnetic properties and structure of electroless Fe-Mo-B amorphous alloy coatings were studied. The changes of AC magnetic and structure during the crystallization process are discussed. The variation law of magnetic parameters of AC samples with composition was preliminarily explained, and the law of loss with annealing temperature during the heat treatment was also studied.
