摘要

采用化学镀法制备了三元非晶Ni-Sn-P合金。详细研究了工艺条件对沉积速率和沉积物浓度的影响。用x射线衍射检查了镀层的结构。在Ni-P合金中加入锡改善了非晶相的成形性。在0.5 M H2SO4、5% HCl、10% NaCl和50% NaOH溶液中测定了镀层的腐蚀性能。研究发现，在Ni-P镀层中添加Sn与化学镀Ni-P镀层相比，通常不能提高镀层的耐蚀性。而Ni-Sn-P非晶镀层的耐蚀性与不锈钢相当。

Preparation, structure and corrosion properties of electroless amorphous Ni-Sn-P alloys

Ternary amorphous Ni-Sn-P alloys were prepared by electroless plating. The influences of technological conditions on the deposition rate and concentration of deposits were studied in detail. The structure of deposits were examined by X-ray diffraction. The addition of tin into Ni-P alloys improved the formability of the amorphous phase. The corrosion properties of deposits immersed in 0.5 M H2SO4, 5% HCl, 10% NaCl and 50% NaOH were determined. It has been found that the addition of Sn into Ni-P deposits did not usually improve the corrosion resistance compared with that of electroless amorphous Ni-P deposits. However, the corrosion resistance of Ni-Sn-P amorphous deposits was as good as that of stainless steel, at last.

期刊介绍： Transactions of the Institute of Metal Finishing provides international peer-reviewed coverage of all aspects of surface finishing and surface engineering, from fundamental research to in-service applications. The coverage is principally concerned with the application of surface engineering and coating technologies to enhance the properties of engineering components and assemblies. These techniques include electroplating and electroless plating and their pre- and post-treatments, thus embracing all cleaning pickling and chemical conversion processes, and also complementary processes such as anodising. Increasingly, other processes are becoming important particularly regarding surface profile, texture, opacity, contact integrity, etc.
