The effects of single surfactant hexadecylpyridinium bromide(HPB) and cetyltrimethylammonium bromide(CTAB) and the combination of HPB and CTAB on the Cr nanoparticle content in the Ni-Cr film prepared by codeposition were investigated. Single HPB/CTAB addition inhibited the oxidation and amorphous transformation of the Cr nanoparticles in the plating bath and effectively stabilized the Cr nanoparticles content at approximately 10 mass% as a function of time. Moreover, the combination of HPB and CTAB formed a cylindrical micelle structure on the Cr nanoparticle surface, which prompted the formation of a layer of NiCr_2O_4. As a result, the Cr nanoparticle content increased sharply to 20 mass%.
