The Electrochemical Colouring of Austenitic Stainless Steel in Environmentally Benign Solutions

该项目将解决以下问题：基于良性化学物质的不锈钢着色替代工艺充分了解迄今为止开发的着色工艺的化学/电化学，包括不锈钢基材所起的作用；确定使用良性化学物质的成本，以确定它们是否适合商业规模的生产；根据工艺参数（即溶液成分）对成功工艺的着色阶段进行调查；处理时间和温度等有色表面特性的研究，如保色性、耐磨性、薄膜稳定性等；研究有前途的着色系统的放大问题。

The project will address the following issues : Alternative processes for colouring stainless steel based on benign chemistriesA full understanding of the chemistry/electrochemistry of the colouring processes developed to date including the role played by the stainless steel substrateTo scope the cost of using benign chemistries to determine if they are viable for manufacture on a commercial scaleAn investigation of the colouring stages for successful processes in terms of their process parameters i.e. solution compositions, process times and temperatures etcAn investigation of coloured surface properties e.g. colour retention, abrasion resistance, film stability etcAn investigation of scale-up issues of promising colouring systems.
