Conclusions
-
1.
The highest elastic limit is attained by removal of a surface layer 10–15 μ thick by electropolishing.
-
2.
Polishing with diamond paste does not impair the mechanical or elastic properties.
-
3.
Polishing with diamond paste produces a surface finish of grade 13–14 (two grades higher than electropolishing).
