Paper Abstract

Metallographical (SEN and rnicrohardneas Investigations of M2 highspeed tool steel incited by a continuous CO2 laser are described. It was apparent that there has been considerable Influence of the graphite coating arid the scanning velocity on melted zone dimensions and its asresolidified structureS In comparison to the uncoated specimens laser melt ing of the specimens coated with a colloidal graphite layer resulted in the increased significantly dimensions of the laseraffected layer and coarser as resolidifled structure. Hardness of the melted zone in the uncoated samples was higher than that of both the graphite coated samples and the conventionally hardened matrix.
