... the uniformity of the polishing plane. If available, a vibratory polisher can also be used for the final polishing step ( Fig. 3.18 ). The vibratory polisher is slower than other automated polishing techniques and is easily contaminated but gives the best possible final surface. This process extends...

... Polishing Vibratory Polishing Etching can be accomplished by swabbing or immersing. Swabbing is preferred when mechanical or vibratory polishing is used. Etching times are usually short, 3 to 20 s, depending on the etchant and the alloy being etched. Table 7.2 lists a number of etchants...

...,” in this book. The last polishing steps can be extended using a vibratory polisher. In between each of the polishing steps, it is recommended that the titanium is etched so the composite can be more effectively polished. Titanium etching can be accomplished using diluted hydrofluoric acid (1 to 1.5 percent...
