Blast case study results

Any cleaning method may he impaired hy contamination or by lack of control. Results of a study in bleach plants suggest that pickhng and glass bead blasting can be more effective than stainless wire brushing and that brushing is more difficult to perform effectively in this case. 

Metallurgy, the science of producing useful metallic materials, almost always requires some kind of compromise. In the case of stainless steel, inclusions of MnS make the steel easier to machine into useful parts, but such inclusions are also the source of pit corrosion. Recently a group of British researchers analyzed stainless steel using a high-energy beam of ions that blasted atoms loose from the steel surface. Studies of the resultant atom vapor revealed the source of the problem. It turns out that when the stainless steel is cooling, the...
