| 摘 要： | 通过调整Ni-W-P化学镀镀液中钨酸钠浓度，获得了钨元素含量不同的三元Ni-W-P镀层。进一步的实验研究表明，随着三元Ni-W-P镀层中钨元素含量的增加，其热稳定性得到显著改善，同时，镀层晶粒转变的激活能值呈增大趋势。三元Ni-W-P镀层的抗垢性随着镀层中钨元素含量的增加而降低，而与镀层表面自由能以及表面粗糙度没有必然的联系。

| Abstract: | In the present work, ternary Ni-W-P deposits with different tungsten content were prepared by varying sodium tungstate concentration in electroless plating. Studies on phase transformation behavior carried out by differential scanning calorimetry (DSC) showed that Ni-W-P deposits exhibited higher thermostability and activation energy with the increase of W composition. Further fouling experiments indicated the surfaces of Ni-W-P deposits with different W content inhibited the adhesion of fouling compared with the mild steel surface. However, there is not necessarily a relationship between the fouling adhesion rate and surface roughness or free energy of the ternary Ni-W-P deposits, but is intimately related to the W content. |
