9361973 Kemp Most electropolishing treatments for stainless steels employ multiple open mildly acidic vessels. Concerns regarding fumes and carryover of more aggressive acids make commercial treatments for titanium unavailable. An automated enclosed single tank electropolishing machine provides and environmentally friendly method for titanium. Workpieces are placed in a dry vacuum tight chamber and necessary fluids are sucked in. Electrolytes and rinse fluid storage canisters are sealed and rinse fluids are continuously deactivated. All servicing is through removal and replacement of sealed tanks. The work includes construction of a working model and the verification of procedures which include pulse current and ultrasonic capabilities. Phase I will also include metallurgical characterization of electropolished titanium and zirconium samples. Phase II includes prototype construction with complete automation and the characterizing of metallurgical effects on representative ferrous, nickel, and reactive alloys. Immediate beneficiary will be the medical industry where titanium is now finished by manual polishing. Longer term the new system can move many electroplate/polish operations into the clean computer controlled environment of the modern production facility.

肯普9361973 大多数不锈钢的电解抛光处理采用多个开放的弱酸性容器。 对烟气和携带更强酸性物质的担忧使得钛无法进行商业化处理。 全自动封闭式单槽电解抛光机为钛合金的抛光提供了一种环保的方法. 工件被放置在一个干燥的真空密闭室和必要的流体吸入。 电解液和冲洗液储存罐被密封，冲洗液被连续停用。 所有维修都是通过拆卸和更换密封罐进行的。 工作包括工作模型的构建和包括脉冲电流和超声波能力的程序的验证。 第一阶段还将包括电解抛光钛和锆样品的冶金特性。 第二阶段包括完全自动化的原型构建以及对代表性的黑色金属、镍和活性合金的冶金效果的表征。 直接受益者将是医疗行业，钛现在是通过手工抛光完成的。 从长远来看，新系统可以将许多抛光/抛光操作转移到现代化生产设施的清洁计算机控制环境中。
