Cast iron surface modification by CO2 laser

摘要

Abstract: In the present paper a globular cast iron surface treated by laser beam has been investigated. In evaluation of the results of experiments with cast iron components, it was found that a structure other than the conventional cast iron structure could be obtained as a result of heat treatment with high power density. Methods like light microscopy, scanning electromicroscopy, X-ray diffraction and DTA were used as test methods in the experiments.!8
