研制出高Bs非晶态磁头材料CcFeNiCuSiB和非晶态录象机磁头材料CoFeNbNiCrSiB分别基本满足了录音磁头和录象磁头的要求。认为Co基非晶合金的耐磨性和脆性与成分有重要关系。在滑动状态下,耐磨性与非晶表面氧化膜的存在有关,与滑动速度有关,还与回火过程中合金内部的结构变化有关。其退火脆化与其内部的晶化过程有密切关系。 Developed high-Bs amorphous CcFeNiCuSiB amorphous head material and amorphous magnetic head material CoFeNbNiCrSiB basically meet the recording head and video head requirements. It is considered that the wear resistance and brittleness of Co-based amorphous alloys are related to the composition. In the sliding state, wear resistance and amorphous surface oxide film is related to the sliding speed, but also with the internal structure of the alloy during tempering changes in the structure. Its annealing embrittlement and its internal crystallization process are closely related.
