| Abstract: | The Study investigates transformation in surface hardening zone of 40Cr steel with CO 2 laser. The microstructures and phase compositions and surface of hardening zone were investigated with S 360 scanning electron microscope. Microhardness of laser hardening zone were measured with CHX-1 microhardness tester. The result revealed that parameters such as power and velocity had a great influence on transformation. |
