Influence of Laser Parameters on Precision in Hybrid Plasma Laser Deposition Manufacturing

Abstract

The present study is a continuation of the previous research on direct metal component fabrication by hybrid plasma and laser deposition manufacturing (PLDM). The overall performance of component depends not only on the plasma but also on the laser. The purpose of this paper is to study the influence of laser parameters, such as average power, repetition frequency and pulse width, on the precision of single layer and analyze the influence rule. The results of this research are presented as follows: (1) The width of single layer decreases with the enhancing of average power and the thickness increases with the enhancing of average power. (2) The width of single layer minishes with the increasing of repetition frequency until it reaches a minimum value, and the thickness increases with the increasing of repetition frequency until it reaches a maximum value. (3) The width of single layer decreases with the increasing of pulse width and the thickness increases with the increasing of pulse width.
