目的：进一步提高电沉积制备Ni-TiN纳米复合镀层的性能。方法选用氨基磺酸盐镀液体系,利用超声脉冲方法在3 Cr13基体上电沉积Ni-TiN纳米复合镀层,研究占空比对纳米复合镀层TiN含量、表面形貌、显微硬度、微观结构的影响。结果随着占空比增加,镀层的硬度和纳米TiN含量先增加,后降低,镀层织构衍射强度增加,结晶度提高,衍射峰变窄。在占空比为0.2时,镀层TiN含量和硬度达到最大值,TiN质量分数为3.85%,硬度为580HV0.1,且镀层表面平整、致密。结论在一定的平均电流密度下,采用合适的占空比可以获得表面平整、致密的Ni-TiN纳米复合镀层。纳米TiN的共沉积影响了镍的结晶过程,不同占空比下制备的镀层中纳米TiN含量不同,引起了镀层晶格畸变,织构发生明显变化,性能改变。
TiN affected the crystallization of nickel. The nano TiN contents of coatings prepared under different duty cycles were different, leading to lattice distortion, significant changes in the texture and altered properties of the coating.
