The surface treatment method for making nitrogen permeates a spring and giving big compression repulsion to the surface. It adopted in order to secure the fatigue limit corresponding to the high lift camshaft. Although graph is a fatigue limit diagram showing the danger of breakage of a spring, it raised the fatigue limit (the difficulty of breaking) by 1.5 times by adoption of oil tempered chromium-silicone alloy steel wire and nitriding. Thereby, it became possible to be used even in the super-high rev exceeding 10,000 RPM, which had not been accomplished with high lift camshaft
