【摘要】 结晶器是钢材连铸技术过程中非常重要的组成部件.结晶器铜板长时间经受钢水冲刷,必须具有很高的耐摩擦磨损、耐腐蚀性能.现研究了钼酸钠含量、电流密度对结晶器铜板电沉积Ni-Co-Mo合金的影响,并对镀层的成分、硬度、耐腐蚀性能进行了测试.在确定镀液成分后通过极化曲线和循环伏安法测试研究了电沉积Ni-Co-Mo合金的机理.用SEM、EDX方法研究了镀层形貌、成分.利用磨损试验机研究了镀层的耐磨损性能.更多还原

【Abstract】 The continuous casting mold is very important part in continuous casting process.The continuous casting mold needs great wear resistance and great corrosion resistance for it is eroded under molten steel in a long time.The influence of content of sodium molybdate and current density on the content of coating,the hardness of coating,the structure of coating,the current efficiency of bath and corrosion resistance is studied.The mechanism of electrodepositing Ni-Co-Mo alloy is studied through polarization curves and cyclic voltammeter curves after the process is confirmed.The morphology and composition of coating is tested by SEM and EDX.The wear resistance of coating is studied by wear testing machine.更多还原
