Grit blasting a distributed roughness based on a 30% probability of exceedence
Abstract
The objective of this study was to obtain a prescribed roughness on a metal surface through control of grit blasting techniques. It includes a description of the equipment used to grit blast the metal samples, the grit-blasting technique, the photomicrographic technique, and the procedure used to characterize the roughness. As a result, calibration curves were obtained which gave surface roughness as a function of grit blasting pressure setting, grit size, and surface material.
