In recent years, much attention has been paid to electroforming as a high-tech manufacturing technique for many micro-devices such as optical readout disk moulds and micro-transducers. However, most of the present research works are focused on using square-wave pulse current to enhance surface finishing and deposit quality, little research result having been reported on the use of other waveforms. In this paper, triangular-, sine- and square-wave pulse currents are used in the investigations. It is shown that a better surface finishing and a smaller grain size can be obtained by using a triangular wave. Different orientation densities of  fiber texture are observed for different waveforms, which are considered to be related to the change of the amount of inhibiting chemical species during the electrodeposition process.
