摘要

:硼氢化物还原浴化学镀镍硼(ENB)涂层由于其优异的硬度和优异的耐磨性而得到了广泛的认可。因此,它们被认为是硬铬的替代品。然而,在镀液中存在少量的有毒重金属,如Pb或Tl,限制了它们的应用。这些金属盐用于稳定浴液,这是避免突然分解所必需的,并且对环境有害。设计了一种不含稳定剂的新型ENB镀槽。在此浴液中,通过络合剂、pH调节剂和还原剂的浓度优化,达到浴液稳定性。该镀液制备的ENB涂层具有表面形貌改变、硬度优异、摩擦系数低等优点。盐雾试验(ASTM B117-07)和动电位极化试验结果表明,新型ENB涂层的耐蚀性明显优于传统的Pb或Tl盐稳定的ENB涂层。总之,目前的ENB涂层是在环保浴中生产的,镀层的性能与传统的ENB镀层接近。

Corrosion resistance of electroless nickel-boron coating in a bath exempt from stabilizer
: Electroless nickel-boron (ENB) coatings from borohydride-reduced bath have received wide acceptance thanks to their excellent hardness and superior wear resistance. Therefore, they have been considered as an alternative to hard chrome. However, the presence of a small amount of toxic heavy metals such as Pb or Tl in the plating bath restricts their application. These metallic salts are used to stabilize the bath, which is necessary to avoid abrupt decomposition, and are harmful towards the environment. A new bath, that is exempt from stabilizer, was designed for ENB plating. In this bath, the bath stability is achieved through the optimization of the concentration of complexing agent, pH adjuster, and reducing agent. An ENB coating from the new bath presents promising properties including modified surface morphology, excellent hardness, low friction coefficient, etc. Salt spray test (ASTM B117-07) and potentiodynamic polarization test results showed that the new ENB coating has a significantly better corrosion resistance than the conventional ENB coatings stabilized by Pb or Tl salts. In conclusion, the present ENB coating is produced in an environmentally friendly bath, and the deposit presents properties close to those of the conventional ENB deposit.
