SLM增材制造复杂不锈钢热管内壁的空化磨粒抛光方法研究
Cavitation abrasive polishing method for inner walls in complex stainless steel heat pipes manufactured by SLM additive manufacturing
摘要
Abstract
Heat pipes play a vital role in efficient heat transfer in various industries,including aerospace.At present,complex heat pipes are widely formed by additive manufacturing technology,and the inner wall is polished by abrasive jet technology.However,the traditional abrasive jet is prone to cause pipe rupture due to excessive pressure during the processing of curved pipes,while pure cavitation jet processing suffers from cavitation attenuation effects,making it difficult to ensure uniform surface roughness along long heat pipe channels.Therefore,this paper proposed a new surface treatment technology.This technology used the cavitation effect to assist in enhancing the material removal effect,and employed the self-developed solid-liquid-gas three-phase jet polishing equipment to polish the inner wall of the heat pipe.The experiment was conducted on the polishing experiment of stainless steel grooved heat pipes manufactured by additive manufacturing at 0°,15°,and 30°.The experimental results show that under the experimental conditions adopted in this study,the solid-liquid-gas three-phase jet polishing technology can effectively remove the surface sticky powder and spheroidization phenomenon and improve the surface step effect.The optimal process parameters for polishing were obtained through experiments,and the surface roughness Ra of the inner flow channel of the heat pipe was reduced from 4.3 μm to 3.3 μm.关键词
