The majority of engineering failures are due to surface initiated effects such as wear, corrosion and fatigue. Surface treatment / coatings (T / C) offer opportunities for prevention of failure and often to reduce costs. T / C of choice is an important part of design for manufacture (DFM) spectrum and has been very elusive work to formalize. With the advent of a knowledge-based system, providing T / C selection of the designer in the early stages of the design process has become a practical reality. Reports of TESS ...
