研究了直径为2 mm的Co43Fe20Ta5.5B31.5块体非晶合金的腐蚀性能。在1 N HCl和1 N H2SO 4溶液中的钝态电流密度分别为10 - 1和101 A/m2，表明该块体非晶合金除了具有已报道的抗弯强度和优良的软磁性能外，即使不含任何耐蚀元素，也具有相当高的耐蚀性。
The corrosion properties of Co43Fe20Ta5.5B31.5bulk glassy alloy with a diameter of 2mm were investigated. The passive current density of the glassy alloy rod in 1N HCl and 1N H2SO4solutions is in the order between 10−1and 101A/m2, respectively, indicating that except the ultrahigh strength and excellent soft-magnetic properties which have been reported before, this bulk glassy alloy also exhibits rather high corrosion resistance even without any corrosion-resistant elements.
