【Abstract】 Based upon the mechanism of rapid prototyping,copper alloy components with complicated shape were directed deposited on base table through laser melting metallic powders which were delivered coaxially.The obtained microstructure is fully dense and evenly distributed.The mechanical properties are somewhat higher than that for casting,and meet the requirement for real usage.更多还原
