Abstract

The production of amorphous electroless nickel (EN) deposits from hypophosphite (H2PO2) containing solutions is well known. The crystallization of the deposits has been studied by differential scanning calorimetry (DSC) and the changes in crystallization behavior with deposit thickness have been attributed to chemical effects. In this work, DSC results from deposits initiated by use of a noble metal catalyst are compared to those from a conventional zincate.

The implication of the DSC data is that the bulk structure of the EN deposit is determined to a large degree by the mechanism of deposit initiation. This is in contrast to the conventional view that solution chemistry is the dominant factor that determines the properties of the deposit.
