| 1 | PRIMARY STUDY FOR THE TECHNOLOGY OF ELECTROLESS PLATING Fe-Al-P ALLOYS显示文摘Manuscript received 24 June 1999 The Fe Al P alloy deposits were plated on copper sheets by electroless plating. The change law of the deposition rate, composition, surface appearance and structure for the deposits was studied by changing the metallic salt ratios (AlCl 3/AlCl 3+FeSO 4), the concentration of metallic salt AlCl 3 and reductant NaH 2PO 2. The optimum plating bath was obtained. It was found that the choices of ligand and reductant were the key of increasing Al content for the deposits. | L.L.Wang,L.H.Zhao,W.Y.Hu, X.L.Shu, X.J.Yuan, B.W.Zhang and X.Sheng Department of Applied Physics, Hunan University, Changsha 410082, China | 1999 | Acta Metallurgica Sinica(English Letters)1999，12，5： | 2 |
| 2 | CALCULATION OF THE VACANCY VOLUME OF METALS BY MODIFIED BROOKS' MODEL显示文摘To modify the shape difference between the spherical vacancy and the realistic vacancy, a shape factor is introduced into Brooks’ vacancy model. It is shown that the modified model is more efficient in predicting the vacancy volume of metals than the original one, and the calculated vacancy volumes of 17 metals by the modified model agree with the values reported in literatures. Furthermore, the present results show that the vacancy shape may contribute 2%-9% to the whole vacancy volume. | W.H.Qi M.P.Wang W.Y.Hu B.W.Zhang | 2004 | Acta Metallurgica Sinica(English Letters)2004，17，6： | 0 |
