MIM metal parts for uav parts

Silicon nitride with high temperature stability, good wear resistance, excellent corrosion resistance, heat resisting impact and the features of low density (weight) has been regarded as a potential ceramic material.

A research project at Oregon state university has been investigating the use of silicon nitride powder injection molding manufacturing for unmanned aerial vehicle (uav) engine components.Goal is to develop a kind of high efficiency and energy saving of power systems, to run in remote locations, and has very low maintenance requirements.

Uav engine project adopts a kind of new material system, by the nano and micro level of silicon nitride powder mixtures.Magnesium oxide and yttrium oxide as sintering additive.Powder by a paraffin wax based multi-component polymer adhesive mixing.Adhesive powder volume solid content (60%) to analyze its properties and forming characteristics.Research involves several steps of development and processing operations.Includes: analysis of torque meter, mix scale up, glue powder performance measurement, the o’s 221 m forming machine for injection molding, adhesive removal, sintering, scanning electron microscope (sem) analysis and mechanical property measurement.

Now in the process of injection molding simulation to evaluate the feasibility of manufacturing ceramic engine, and optimum technological parameters were determined.The study using a successful development of design parameters, manufacturing silicon nitride powder injection molding are engine parts is possible.
