硝酸镧对电沉积Ni-P合金镀层性能的影响

Effect of Nitric Acid Lan on Function of Electricity Deposition Ni-P Metal Alloy

Ni-P合金以其优异的耐蚀,耐磨性能,以及对环境的友好性,代替铬广泛应用于机械、汽车、电子、半导体等领域。但是传统的Ni-P合金镀层要么耐蚀性能好、力学性能差,要么力学性好,耐蚀性能差。此课题用在镀液中加入硝酸镧的方法,寻求解决之道。通过做不加硝酸镧和加硝酸镧的对比实验,运用XL300 W/TWP扫描电镜对镀层表面形貌进行扫描,结果表明,在镀液中添加硝酸镧可以提高镀层的沉积速率,改善镀层表面形貌和组织结构,提高镀层的耐蚀性能。

The Ni-P metal alloy excellently bear eclipse with it and bear to whet function, and replace chrome to the amity of enviromnent extensive application at the realms, such as machine, car, electronics and semi-conductor etc. But tradition of the Ni-P metal alloy plate a layer to want Yao to bear eclipse function good, mechanics function bad, the Yao mechanics good, bear eclipse function bad. Thd topic used to join the method of sparse soil in plate the liquid and look for a solution Pass to do the contrast that don＇t add nitric acid Lan and add nitric acid Lan experiment, usage the XL300 W/TWP scan electricity mirror to carry on scan towards plating the 1 F surface facial look, result enunciation in plate the liquid add nitric acid Lan not only can exaltation plate the machine function of layer, and to exaltation plate a bear of layer eclipse function also beneficial.
