摘要: 化学镀非晶态Ni-P镀层初期沉积过程和沉积层状态是影响结合强度的决定性因素.对不同基体材料初期沉积的观察发现,有些非晶态镀层的初期沉积中含有微晶.微晶的产生与否与基体材料以及镀层材料晶格的错配度有关,当镀层与基体材料点阵常数相差不大,镀层的初期沉积沿基体晶格外延生长出现微晶层,反之,点阵常数相差较大时,初期沉积物中未发现微晶.

Abstract: The initial process and mophology of electroless nickel played a domination role in adhesive strenghth of EN coating. The structure of initial deposits on certain matrixes was observed by TEM analysis. The deposition of a extremaly fine grain film depended on relative contrast between a coating and a matrix in crystal lattice parameters. When the coating and matrix had similar srystal lattice parameters. A extremely fine grain film was obtained. On the contrary, when the crystal lattice parameters were very different, a amorphous structure was observed.
