Title: | Study of electroless Ni-P deposition on aluminium | Authors: | Backović N. Jančić M. Radonjić L. |
Issue Date: | 16-Apr-1979 | Journal: | Thin Solid Films | Abstract: | The investigations performed have shown that the deposition of Ni-P on aluminium starts by nucleation of nickel primarily at grain boundaries and at defects present on the aluminium surface. The shape of the deposited nuclei is hemispherical. These nuclei serve as a catalytic surface for Ni-P deposition. The process of electroless Ni-P deposition continues on deposited nickel nuclei. The Ni-P nuclei are observed to have the same hemispherical shape as the nickel nuclei. The growth and coalescence of such nuclei result in a continuous layer of Ni-P on the aluminium surface. X-ray analysis of the as-plated deposits have shown the presence of a clearly pronounced extended peak corresponding to nickel. In the small angle range a broadened diffraction line with two small extended peaks is present but these are difficult to identify. After heat treatment the deposits have a very well-defined crystal structure and it was confirmed that two crystalline phases-nickel and Ni3P-were present. © 1979. | URI: | https://open.uns.ac.rs/handle/123456789/14571 | ISSN: | 00406090 | DOI: | 10.1016/0040-6090(79)90358-4 |
