Laser surface hardening of engine camshaft cams
Abstract
The publication describes research into the laser hardening process of the camshaft cams surface. Samples of camshaft cams made of structural bearing steel were hardened using a powerful fiber laser LS-15. The effect of altering the laser surface hardening process parameters on the microstructure and microhardness of the surface was investigated. Also, the influence of low-temperature tempering after laser surface hardening was shown.
