Abstract

The paper describes the fabrication of micro gears of diameter and height 1 mm by micro powder injection moulding. 316L stainless steel powder of 2.4 µm (d50) is mixed with a multi-component wax-based binder system. The feedstock is then injection-moulded into micro gears followed by debinding and sintering. The microstructure of the micro gear at its tooth and hub is studied by electron backscattered diffraction. The average grain size at the hub is ~ 5 µm. However, a high content of annealing twin and a significant grain growth is found at the tooth.

Graphical abstractMicro gears of diameter and height 1 mm is by micro powder injection moulding of 316L stainless steel powder (2.4 μm) feedstock. The microstructure of the sintered micro gear at its tooth and hub is studied by electron backscattered diffraction and different grain size is found at these two regions.Figure optionsDownload full-size imageDownload as PowerPoint slide
