DESCRIPTION:
Ample evidence exists in support of why camshafts subjected to the pulsed plasma nitriding process are superior to all others. In the testing laboratory, on the dyno or in racing engines of the most demanding and hostile operating environments, data indicates reduced component wear, particularly when using sliding-friction tappets. This is true, regardless of basic tappet design.

Wear surface hardness is also increased, on the order of values in the range of 55-70 on the Rockwell “C” scale. As previously indicated, the pulsed plasma process tends to “fill in” slight wear surface imperfections (prior to parts use) that reduce friction, further extending parts life and enhancing the effectiveness of lubricants. This “surface improvement” actually occurs as the part is bombarded with nitrogen. As compared to micro-peening where smaller shot is used for a better surface, pulsed plasma nitriding could be considered as chemically shot-peening the surface (on the atomic level).

Finally, and also along the lines of reduced component wear, the pulsed plasma process reduces (typically eliminates) problems associated with “micro welding,” the combined result of wear surface fracture and material disruption traceable to both high temperature and impact stress loads at the camshaft lobe and lifter interface.

COMP Cams® has, through a rigorous process of exploring and applying the most recent technologies that can extend the life of camshaft lobes and lifter faces, demonstrated its long-term intent to bring the most advanced techniques and processes to its products. When combined with ongoing and intense research and engineering efforts directed to understanding the many complexities of contemporary valve trains and systems, the results stand on their own technological merits. Superiority is not claimed, it is earned.
