... surface finish (roughness average, or R a ) on ground surfaces is typically in the range of 0.2 to 1 μm, whereas lapped and polished surfaces can have R a values of less than 0.05 μm. The material removal rates in lapping and polishing are usually an order of magnitude less than in grinding. At the...

... research data to support field experience. Quantitative data on the increase in critical pitting temperature in ferric chloride (FeCl 3 ) (ASTM G 48) shows that pickling provides a 2.5 to 10 °C (4.5 to 18 °F) improvement in performance ( Fig. 1 ). While not large, the improvements in lightly ground...
