BD电镀黑铬工艺的研究

Study on Electrodepositing Black Chromium

在大量的实验基础上,详细介绍了一种既能应用于航空、照相机、仪器、仪表等光学系统中,又能应用于其它日用工业品中的电镀黑铬工艺。BD添加剂的应用,大大改善了黑铬镀层质量,增加了镀铬的阴极极化,扩大了黑铬区的电流密度范围,显著改善了镀液的深镀能力和均镀能力。整个工艺的投资同国内其它黑铬工艺相比,本工艺投资小、见效快,能很快应用于生产中。

It is developed that a new type of electrodepositing black chromium technology based on many experiments. This technology can be used in aerospace industry, camera industry, instrument industry and so on. BD additive used in this technology can widen the polarization of the cathode, expand the range of the current density in the black area, improve the ability of the deep plating and even plating. This technology has the advantages of small investment and fast income of the technology compared to other electrodepositing black chromium technologies. It can be applied in industry easily.
