摘要/Abstract

摘要： 在以磷酸盐-硅酸盐复合盐系为基础的电解液中,加入不同浓度的着色盐NH₄VO₃,探讨其浓度变化对微弧氧化膜层宏观形貌、黑度、微观结构、物相组成、耐蚀性以及热控性能的影响.结果表明:随着NH₄VO₃浓度的增加,膜层黑度值逐渐减小,颜色加深,但当其浓度超过临界值时,膜层成膜性变差.使膜层呈现黑色的原因是V₂O₃物相的生成.NH₄VO₃的加入使得黑色膜出现了自封孔现象,从而使得膜层的耐蚀性得到明显改善.黑色膜的电化学耐蚀性比基体和未加着色盐的膜层分别提高了5个和3个数量级.膜层吸收率最大为0.927,发射率最大为0.882.黑色膜层的热控性能和耐蚀性得到了同时提升.

Abstract: The effects of different concentrations of NH₄VO₃ coloring agent on the morphology, darkness, microstructure, phase composition, corrosion resistance, and thermal control properties of the micro-arc oxidation (MAO) coatings were investigated by incorporating varying concentrations of NH₄VO₃ coloring agent into the electrolyte based on the phosphate-silicate solution system. The results demonstrated that as the concentration of NH₄VO₃ increases, the darkness of the coating gradually decreases while its color intensifies. However, when the concentration exceeds a critical value, coating formation deteriorates. The black appearance of the coating is attributed to V₂O₃ phase formation. The addition of NH₄VO₃ promotes a self-sealing micro-pore phenomenon in the black coating, significantly enhancing its corrosion resistance. Electrochemical detection revealed that corrosion resistance of the black coatings is 5 and 3 orders higher than thatof both substrate and non-colored coatings, respectively. Moreover, maximum absorptance and emittance values for the black coatings are measured as 0.927 and 0.882, respectively. Both thermal control and corrosion resistance properties for a black coating are achieved simultaneous improvement.
