摘要

为解决当前激光选区熔化成型过程难以按需在零件上自由布置不同材料的难题，基于多漏斗供粉+柔性清扫回收粉末原理，对异质材料零件激光选区熔化增材制造技术展开了研究，详细探讨了成型机理、粉尘污染防范机制及异质材料数据处理方法。采用CuSn10

4340两种不同的合金材料进行了工艺实验验证。实验表明，该方法能自由地在不同层间或同层内不同区域按需布置不同的材料；所得块状异质材料零件的铜合金材料区域Fe元素的平均质量百分含量可控制在2%以下，钢材料区域Cu元素的平均质量百分含量可控制在1%以下；成功成型了一个具有复杂外形及微细材料区域特征的异质材料齿轮零件，零件异质材料区域不受零件复杂外形限制，可自由按需布置材料，0.5 mm宽的层内异质材料区域也能被较好地表达出来，尺寸误差不超过±0.1 mm。

Abstract

To solve the problem of free placement of different materials at any location on a part during selective laser melting

the manufacturing technology of selective laser melting of heterogeneous material parts was studied. This method is based on supplying powder through multiple funnels and cleaning and recovering of powder using a flexible scraper. The processing mechanism

the prevention mechanism of powder cross contamination

and the data processing method of heterogeneous material parts were discussed in detail. Two materials

namely

a CuSn10 alloy and 4340 steel

were used to verify the technology. Experiments show that this method can effectively solve the difficult problem of heterogeneous material placement during selective laser melting and can realize the formation of heterogeneous material parts. Specific results of the study are as follows: (1)Heterogeneous materials can be arranged freely in different layers or in different zones of a single layer. (2) For a bulk heterogeneous material part

the average mass percentages of Fe in the copper alloy region and of Cu in the steel region can be controlled to less than 2% and less than 1%

respectively. (3) A heterogeneous material gear part with a complex shape and the characteristics of a narrow material region is successfully formed. The heterogeneous material distribution of the part is not limited by the complex shape

and the materials can be arranged freely as needed. The heterogeneous material region in one layer with a 0.5 mm width can also be well expressed

and the dimensional error does not exceed ± 0.1 mm.
