Study on Laser Rapid Prototyping of High Thin-Walled Revolved Parts with Variable Diameters Based on Inside-Laser Coaxial Powder Feeding

Abstract:

The article firstly puts forward an experiment scheme for the study according to the laser rapid prototyping of high-level revolved body accumulate based on inside-laser coaxial powder feeding. And the changes of Z-axis feeding and power regulation in the progress are observed by high speed CCD technology. Then the organization and performance of laser cladding rapid prototyping parts are analyzed. The study shows that the microstructure of the parts is fine and has the characteristics of directional solidification and rapid solidification. The hardness of the parts is better than that of the castings and the ordinary steel parts after heat treatment. The hardness of cladding layers is floated , but there are little differences between each layer.
