Study on Structure and Properties of Alloy Nodular Cast Iron Roller with Laser Heat Treatment

Abstract:

Article Preview

The microstructure analysis and hardness test were carried out on the surface of alloy nodular cast iron roll treated with CO2 laser of power 5 KW by optical microscopy, Rockwell hardometer and micro-hardometer. The results indicate the cladded layers with laser heat treatment are divided into melt region, phase change region and substrate region. The dimension and microhardness for every region are related to laser power, scanning speed and process parameters. The fatigue life of alloy nodular cast iron roll treated with laser increased remarkably.
