Abstract
The process of electrochemical polishing is applied to finish the surface of the titanium orifice ring used in a St. Vincent's prosthetic mechanical heart value. The optimum process parameters for polishing flat specimens were determined from a fractional factorial design and a few single-factor experiments. A good shiny surface finish of 0.08 μm Ra, free from any surface or sub-surface defects, was produced in 45 s of polishing time. Subsequent experimental results with shaped electrodes indicated that the titanium orifice rings could be polished to approximately 0.09 μm Ra, this comparing favourably with the surface finish of 0.08 μm Ra that could be achieved by manual polishing.
