The Wear-Resistance of 3Cr2W8V Steel with Cave Pit Non-Smooth Surface Processed by Laser
The cave pit non-smooth surface on the 3Cr2W8V die steel were processed by laser and the size and microstructure of the non-smooth units were studied. The wear-resistance and hardness of the 3Cr2W8V steel with non-smooth surface were measured. The results show that the wear-resistance characteristic is better if the distance between non-smooth units is smaller. The size (the depth, the width), the hardness and the microstructure of the units vary with the laser parameters. When the current intensity and the pulse duration increase, the microstructure of non-smooth unit becomes coarser for the increase in the width and volume, as a result, the hardness decreases and the wear-resistance improves. The wear-resistance of the non-smooth material under higher current intensity and longer pulse duration was found to be better in the experiments. The improved degree of wear-resistance lies in the combination of size, microstructure and hardness of non-smooth unit.
