Galvanic corrosion of powder sintered component and improvement of material removal rate for biomachining

The biomachining properties of copper and powder sintered metal have been investigated using a white-light interferometer, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). A groove was machined on the copper surface and a porous structure was produced on the powder sintered metal in the biomachining. The groove depth of the copper was directly dependent on time but the porous structure depth of the sintered metal was...
