【Abstract】 The mechanism of laser strengthening of cast iron surface was investigated. The change law of structure and properties of different kinds of cast iron surface under the irradiation of CO₂ continuous laser were studied. A selection principle of laser suface strengthening process for various kinds of cast iron was put forward.更多还原
