Abstract

In order to investigate the process and performance of QSn6.5-0.1 tin bronze manufactured by selective laser melting (SLM) technique, the orthogonal experiment of three factors and four levels were designed to study the influence of laser power, scanning speed and scanning distance on the density. SEM, OM, Micro-CT and microhardness tester were used to study microstructure and hardness. The results show that the density of Sn-Cu SLM is up to 98.71% with optimized process. The microstructure is net-like dendritic structure with homogeneous (α+δ) phase and α phase. Micro vickers hardness (HB) is about 45% higher than the traditional casting of the soft state (700~900 MPa). The wind wheel model manufactured directly has high compactness. It is indicated that the QSn6.5-0.1 tin bronze alloy parts with better performance can be manufactured directly by SLM.
