This research demonstrates improved structure and thickness of chilled layers in camshaft cams, suggesting better performance for automotive applications.
This work is devoted to the development of an effective technology for strengthening camshaft cams cast from gray pearlitic cast iron. As a result of the conducted studies, it was proven that the manufacture of camshafts from gray cast iron with chilled cams is promising for automobile engines, especially under intensive operating conditions. The most rational technology for whitening the working surface of camshaft cams made of gray cast iron is casting in a sand-clay mold with the installation of coolers in the cavities that form the nose of the cam.
