摘要:
通过电沉积将纳米Y2O3颗粒掺进Co-W镀层中，在黄铜表面制备出Co-W/Y2O3复合镀层。研究了纳米Y2O3颗粒掺杂对Co-W镀层的形貌、成分、晶粒尺寸、晶粒生长取向、耐腐蚀性能以及磁性能的影响。结果表明：镀液中添加2.5 g/L纳米Y2O3颗粒时，制备出平均晶粒尺寸仅为35.7 nm的Co-W/Y2O3复合镀层，其平整度和致密性最好，并且呈现(200)晶面择优取向。与Co-W镀层相比，该复合镀层具有更好的耐腐蚀性能和磁性能，腐蚀电流密度降低了约一个数量级，仅为8.54×107 A/cm2；矫顽力增大16 560 A/m，比饱和磁化强度提高约10 A·m2/kg。纳米Y2O3颗粒掺杂既影响了Co-W镀层的结晶形核和晶粒生长过程，还影响了Co沉积过程，从而导致复合镀层的平整度、致密性、耐腐蚀性能以及磁性能表现出差异。
Abstract:
Co-W/Y2O3 composite coating was prepared on the brass substrate via electrodeposition by incorporating Y 2O3 nanoparticles into Co-W coating, and the effect of Y 2O3 nanoparticles incorporation on the morphology, composition, grain size, grain growth orientation, corrosion resistance and magnetic property of Co-W coating were investigated. The results demonstrate that a Co-W/Y 2O3 composite coating has optimal surface smoothness and compactness, with an average grain size as small as 35.7 nm and exhibit a preferred orientation of (200) crystal plane is prepared in the electrolyte containing 2.5 g/L Y2O3 nanoparticles. Compared with Co-W coating, the composite coating exhibits superior corrosion resistance and enhanced magnetic property. Specifically, the corrosion current density was reduced by approximately one order of magnitude to 8.54×10 7 A/cm2, while the coercivity increased by 16 560 A/m, and the saturation magnetization improved by about 10 A·m2/kg. The incorporation of Y2O3 nanoparticles not only influence the crystallization nucleation and grain growth process of Co-W coating, but also modulate the Co deposition behavior, ultimately leading to variation in the surface smoothness, compactness, corrosion resistance and magnetic property of Co-W/Y2O3 composite coating.
