Understanding Abrasive Media Blasting Basic Finishing Guide

Abrasive blasting can make a good finish better and cleaner. It also produces a better tooth for bonding. It is estimated that the surface area of metal increases as much as ten times as a result of the abrasive impact action. This increases the surface to which paint, coating or plating can adhere.

control strategy can be implemented. To characterize surface roughness, mechanical profilometry was used to collect average roughness parameter, R a. Decreasing blast distance from 6” to 4” gave ΔR a = +0.22 µm and from 8” to 6” gave ΔR a = +0.22 µm. Increasing blast pressure from 42 psi to 60 psi decreased the R a by 0.33 µm.

Introduction to Blasting

Introduction to Blasting Blasting is the acceleration of particles by air or mechanical means to a surface or work piece to achieve a variety of physical effects. Surface effects are determined by media type, size, speed, and direction of impact. The visual appearance of a blasted surface tends to be a dull to bright satin-matte finish.
