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.
The Parkerizing process cannot be used on non-ferrous metals such as aluminium, brass, or copper. It similarly cannot be applied to steels containing a large amount of nickel, or on stainless steel.
