摘要： 目的:采用几种工艺参数制作激光熔积钴铬合金试样,研究其表面EDS能谱的变化。方法:根据激光功率、扫描速度、送粉速率数值的不同（激光功率2500~3000 W、扫描速度5~15 mm/s、送粉速度3~6 r/min）,采用正交实验设计9组试验组,利用自主研发的Co-Cr合金金属粉末,分别通过Rofin DL 035Q激光熔附系统制作3个圆柱形SLM钴铬合金试件（直径10 mm,厚度3 mm）,对9组试件分别行EDS能谱分析,测定试件表面成分及含量。结果:在设定的工艺参数下,9组试件的EDS能谱分析结果(Co：62.98%~67.13%,Cr：25.56% ~28.50%,Si：0.49%~1.23%)均与临床常用钴铬合金组成相似。结论:根据表面EDS能谱分析结果,在本实验采用的各种参数下,制成的SLM钴铬合金试件的表面成分稳定、可控。

Abstract: PURPOSE: To fabricate selective laser melting cobalt-chromium alloy samples by different processing parameters, and to analyze the changes of energy dispersive spectrum(EDS) on their surface. METHODS: Nine groups were set up by orthogonal experimental design according to different laser powers,scanning speeds and powder feeding rates(laser power:2500~3000 W, scanning speed: 5~15 mm/s, powder feeding rate: 3~6 r/min). Three cylinder specimens(10 mm in diameter and 3 mm in thickness)were fabricated in each group through Rofin DL 035Q laser cladding system using cobalt-chromium alloy powders which were developed independently by our group.Their surface compositions were then measured by EDS analysis. RESULTS: Results of EDS analysis of the 9 groups fabricated by different processing parameters(Co：62.98%-67.13%,Cr：25.56%-28.50%,Si：0.49%-1.23%) were obtained. They were similar to the compositions of cobalt-chromium alloy used in dental practice. CONCLUSIONS: According to EDS results, the surface compositions of the selective laser melting cobalt-chromium alloy samples are stable and controllable, which help us gain a preliminary sight into the range of SLM processing parameters.
