Electrodeposited Co-W alloys with Self Assembling Nanoscale Metal Multilayers (SANMM)

由于发现了一种可行的电镀替代硬铬电沉积的方法，具有更好的腐蚀和摩擦学性能，因此出现了获得技术优势的机会。该涂层是一种基于电沉积Co-W合金的自组装纳米金属多层膜。非常高的硬度和偏析的纳米结构提供了极好的磨损率，这比硬铬对马氏体不锈钢对接的磨损率低一个数量级。

An opportunity for technological advantage has arisen due to the discovery of a viable electroplated replacement for hard chrome electrodeposit with improved corrosion and tribological properties. The coating is a self-assembling nanoscale metal multilayers film based on electrodeposited Co-W alloy. Very high hardness and segregated nanostructure give excellent wear rate which is an order of magnitude lower than hard chrome against a martensitic stainless steel counterface.
