ABSTRACT:
A process and apparatus is disclosed for the fabrication of press plates hardened by the use of plasma ion nitriding techniques to produce wear resistant decorative laminate containing alumina grit while improving associated press plate useful life. The application of this process to press plates having exacting final microfinish requirements is possible due to the determination of interdependancies between parameter settings and expected results. These interdependancies include the work piece geometry, surface and subsurface structure and desired results, process temperatures, pressures, and duration of heat-up time, thermal loading, reflective radiation and heat effects, cooling systems, and gas mixture composition.
