POLYKRISTALLINER DIAMANT MIT EINER AN KATALYSATORMATERIAL ABGEREICHERTEN OBERFLÄCHE |
摘要 |
A method of machining a polycrystalline diamond material including a matrix of interstices containing a catalyzing material and a volume close to a working surface thereof substantially free of catalyzing material which comprises the steps of treating the volume to render the polycrystalline diamond electrically conductive, and using an electron discharge machining technique to machine the polycrystalline diamond. In one embodiment, the treatment comprises applying a conductive material layer to a surface of the diamond. |
