本文介绍了一种新的电磨削方法，用于制造具有生物材料和其他工程应用所需特性的加工表面。传统的生物材料，如不锈钢和钛合金，需要提高化学稳定性和耐磨性，这取决于表面氧化层的质量。然而，仅通过氧化铝抛光精加工很难生产出足够均匀的氧化层。本研究中提出的电磨削方法在加工过程中将电流施加到磨削液中，改善了加工表面上的氧化层形成，从而实现了具有极厚且稳定氧化层的加工表面。与氧化铝抛光相比，电磨削加工出的表面具有优异的耐腐蚀性。
A new electrical grinding method for the fabrication of machined surfaces with desirable characteristics for biomaterials and other engineering applications is presented. Conventional biomaterials, such as stainless steel and titanium alloy, require enhanced chemical stability and wear resistance, which are dependent on the quality of the surface oxide layer. However, it is difficult to produce sufficiently homogenous oxide layers by alumina polish finishing alone. The electrical grinding method proposed in this study, in which electric current is applied to the grinding fluid in the machining process, improves oxide formation on the finished surfaces, thereby realizing finished surfaces with extremely thick and stable oxide layers, Compared with alumina polishing, electrical grinding yields machined surfaces having excellent corrosion resistance.
