To avoid the Ambiguity appearing in the Formulation Process using the Numerical Methods of Partial Differentrial Equations it is Important to Satisfy the following Conditions given by Fletcher C.A.J. 1989, p18 :

 "The governing Equations and Auxiliary (Initial and Boundary) Conditions are Well-Posed Mathematically if the Following three Condtions are met:

A major concern for plasma coatings is how wear resistant they will prove to be on the final product. Since

plasma coatings are a popular use for automobile engines, these coatings are tested through strenuous

conditions. If the coating on the engine itself wears off at a fast rate than the life expectancy of that

particular engine or part becomes a problematic concern. With the plasma coating wearing off, the parts

originally being protected will become exposed to melting temperatures, corrosion and other potentially
