电化学喷射加工技术为大面积表面结构化和微细加工提供了一种有效的方法，在这种方法中，近表面的冶金性能得到了保证，并且不会受到热载荷的不利影响。在这里，掺杂电解质是专门为喷射技术开发的，以利用在能束过程中发现的高斯能量分布。与标准电解液相比，这可以使溶解开槽减少26%，定义的精度指标提高284%。这是通过在能量分布曲线内的离散点过滤低能量来实现的。提出并研究了电流过滤和刷新率的两种基本机制，以支持使用该方法发现的性能增强。这项研究的目的是证明，通过优化特定于喷射过程的电化学，可以实现过程保真度和灵活性的阶段性变化。
Electrochemical jet processing techniques provide an efficient method for large area surface structuring and micro-milling, where the metallurgy of the near-surface is assured and not adversely affected by thermal loading. Here, doped electrolytes are specifically developed for jet techniques to exploit the Gaussian energy distribution as found in energy beam processes. This allows up to 26% reduction in dissolution kerf and enhancements of the defined precision metric of up to 284% when compared to standard electrolytes. This is achieved through the filtering of low energy at discrete points within the energy distribution curve. Two fundamental mechanisms of current filtering and refresh rate are proposed and investigated in order to underpin the performance enhancements found using this methodology. This study aims to demonstrate that a step change in process fidelity and flexibility can be achieved through optimisation of the electrochemistry specific to jet processes.
