Measuring the effects of some laser parameters on the surface and near surface region of laser treated cast iron cylinder bore

Abstract

The environmental and polluting materials emission standards in Europe are going to be always stricter, so in order to keep up with them, one of the largest European automotive manufacturers performs a laser treatment on the cylinder bores of their combustion engines. In this article the laser treated layers of cast iron cylinder bores with lamellar graphite are investigated with a FISCHERSCOPE^\unhbox \voidb@x \hbox \textregistered HM2000 XY microhardness measurement system and with a FEI Nova Nanolab 600 SEM/FIB dual beam scanning electron microscope (SEM), equipped with focused Ga-ion beam source. Four samples treated by two different laser sources in three configurations were investigated.
