中文摘要: 以聚氨酯泡沫树脂为基体,采用化学镀、电沉积、热解和氢气还原的方法制备出网状结构的泡沫Ni-Mo合金。对该泡沫合金的形貌、镀液组分与合金组分的关系和合金的抗拉强度、抗腐蚀性、高温抗氧化性进行了分析研究。试验结果表明:合金中Mo含量随着Na2MoO4浓度增加而增加,该泡沫合金骨架平整,泡沫Ni—Mo合金抗拉强度、耐腐蚀性和高温抗氧化性优于泡沫镍,在中性盐雾试验中的抗腐蚀性加强,高温抗氧化性也增强。
Abstract:Reticulated Ni-Mo foams were prepared through polyurethane as framework by four step method consisting of coating electrolysis, electrodeposition, pyrogenation and hydrogen reducing. The morphology, relationship between compositions of bath and compositions of deposits, tensile strength, salt spray corrosion and antioxidation of alloys foam in high temperature were investigated. The results show that the Mo content in alloys foam increase with the increase of concentration of Na2MoO4, Ni-Mo foams have excellent properties such as even struts, good salt spray corrosion resistance and good oxidation resistance.Anticorrosion in salt spray corrosion experiments and antioxidation in high temperature improved the increasing of Mo content.
