The professional science master's, or PSM, got its start in 1997 as a way to better and more rapidly equip students with much-needed skills in the science, technology, engineering, and math (STEM) fields. Now nearly 300 PSM programs are offered by KGI and 128 other institutions.
Parkerizing, bonderizing, phosphating, or phosphatizing is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of a chemical phosphate conversion coating.s for all chemical conversion coatings, the Parkerized surface must be completely covered with a light coating of oil to maximize corrosion and wear resistance, primarily through reducing wetting action and galvanic action.
Hard anodizing is not teflon. And it is not a coating. The outer surface of the aluminum is oxidized via an electro-chemical process, creating a surface harder than stainless steel. But most hard anodized cookware has a non-stick coating (Teflon or similar PTFE) on the cooking surface.ut I really miss the non-stick surface for frying pans. I've seen some frying pans recently that were labelled Hard anodized coating. Now I know what anodizing is, but the surface looks just like regular old Teflon Silverstone.
