【摘要】 用座滴法研究了Fe78B13Si9原始非晶条带和其预退火条带与液态Sn的润湿性.结果表明,与普通晶态合金之间的润湿规律不同,原始非晶Fe78B13Si9基底与液体Sn的平衡接触角并不随温度升高而单调减小.与原始非晶Fe78B13Si9基底相比.当润湿温度低于预退火温度时, Fe78B13Si9非晶基底的预退火使其平衡接触角显著增大;当润湿温度高于预退火温度时,Fe78B13Si9基底的预退火对其平衡接触角没有明显影响.更多还原

【Abstract】 The wetting behaviors of liquid Sn on three types of Fe78B13Si9 substrate, an amor-phous substrate and two types of pre-annealed substrate at 400 and 450℃ , were studied by the sessile drop technique between 350-450℃. The equilibrium contact angle of the amorphous Fe78B13Si9 substrate did not decrease monotonically with increasing temperature, which is evidently different from that of polycrystalline alloy substrate. Pre-annealing of Fe78B13Si9 substrate made its wettability very poor when the wetting temperature was lower than the pre-annealing temperature. However, when the wetting temperature was higher than the pre-annealing temperature, pre-annealing of substrate had little effect on the equilibrium contact angle.更多还原
