摘　　要：文章研究了Ni-Cu-P复合涂层的电沉积制备工艺及其润湿行为,利用电沉积法在304不锈钢上制备具有分级微纳结构的Ni-Cu-P三元涂层,对其表面形态、相组成以及润湿行为进行系统性研究.通过控制电流密度来调节涂层形貌和表面化学性质,以获得良好的疏水性能.在确定最优电流密度后,对表面进行退火处理以调整其化学成分.结果表明:Ni-Cu-P涂层电沉积的最佳电流密度为50 mA/cm^(2),无需额外进行退火处理.Ni-Cu-P涂层XRD图谱显示主要相为Ni立方相,涂层表面呈现均匀且致密的菜花状结构,表面粗糙度约为(3.8±0.1)μm,静态水接触角为(143.8±3.9)°,接触角滞后约5.5°.This study meticulously explored the intricate process of electrodeposition for the fabrication of Ni-Cu-P composite coatings,alongside a comprehensive examination of their associated wetting behavior.The ternary Ni-Cu-P coatings with hierarchical micro-nano structures were fabricated on 304 stainless steel through electrodeposition method,subsequently accompanied by a comprehensive analysis of surface morphology,phase composition,and wetting properties.The morphology of the coatings and the surface chemistry were optimized by regulating the current density to achieve optimal hydrophobic performance.Following the identification of the optimal current density,an annealing treatment was employed to modify the chemical composition of the surface.The results indicated that the optimal current density for the electrodeposition of Ni-Cu-P coatings was determined to be 50 mA/cm^(2),and no additional annealing treatment was necessary.The X-ray diffraction spectrum of the Ni-Cu-P coatings predominantly displayed phases of Ni in a face-centered cubic structure.The surface morphology of the coating revealed a uniform and dense cauliflower like appearance,with a measured surface roughness of approximately(3.8±0.1)μm.Furthermore,the static water contact angle was recorded at(143.8±3.9)°,exhibiting a contact angle hysteresis of about 5.5°.
