摘　　要：采用工业原料在铜模铸造的条件下制备出了ф3 mm的Fe41Co6Cr15Mo14C15B6Y2Mn1和Fe41Co6Cr15Mo14C15B6Y2N1块状非晶合金圆棒,采用X射线衍射(XRD)仪和盐酸溶液浸泡腐蚀试验分别对合金的非晶形成能力和耐蚀性进行了研究。结果表明,采用工业用料制备的铁基非晶合金中添加N时有更大的非晶形成能力和更优异的耐腐蚀性能。Bulk amorphous alloy rods of Fe41Co6Cr15Mo14C15B6Y2Mn1 and Fe41Co6Cr15Mo14C15B6Y2N1 with a diameter of 3 mm were prepared by copper mould casting using raw industrial materials.The glass-forming ability and anti-corrosion property of the alloys were analyzed by X-ray diffraction（XRD） and immersion corrosion testing.The results showed that the amorphous alloys with N addition prepared using raw industry materials had better glass-forming ability and anti-corrosion property.
