Abstract

The pollution materials emission standards in Europe are going to be more strict. In order to meet the environmental standards, a European automotive manufacturer performs a finishing laser treatment on the honed cylinder bores of their V-engine blocks. Samples of laser treated cast iron cylinder bores with lamellar graphite were investigated. In order to evaluate the microstructure and grain size of the laser-treated layer, scanning electron micrographs were taken on cross-sectioned samples with a scanning electron microscope/focused ion beam dual-beam instrument. The samples were found to be ultra-fine grained. Nanoindentation hardness measurements of the surface layer showed a clear linear trend between the laser power deasity in the applied range and the measured hardness. Additional micro-hardness measurements suggest an annealed region beneath the surface.
