Indicates diamond conversion into graphite within the irradiated area.

Diamond micromachining. At 633 nm mea sured simultaneously with zb. As a cutting tool material diamond is superb because of its high hardness stiffness thermal conductivity low friction in air and relative inertness. Pseudo binary phase di agram of wc co from upa98. However the diamond irradiated with a dose of 4 10 15 ionscm 2 promotes the graphitization process with a reduction in activation energy from 2906 j in a pristine diamond to 1915 j. Optical transmission image zc. Diamond is a wide bandgap semiconductor material with high mechanical strength and thermal stability and therefore is an ideal candidate for micro electromechanical devices. Mechanical micromachining by drilling milling and slotting 165 fig. The result confirms the optimal ion dose to influence the diamond iron affinity. Diamond machining is commonly used to produce very smooth surfaces with highly precise geometry for optical and many other applications. Micromachining provides a more flexible manufacturing of microparts with a much wider choise of materials. Diamond makes a superb choice for a cutting tool. Surface of a diamond sample before and after application resolution of diamond micromachining using a near of two laser pulses in the center of the imaged area. Diamond micromachining is of particular interest for the optical and electronic industries. In this paper diamond surface micromachining technology used for fabricating diamond film devices is reported. To meet this need the technique of choice for precision micromachining of diamond tools is increasingly the industrial ultrafast laser.

The manufacturing is done by using the classic cutting techniques of milling drilling and turning as well as microtools made of carbid or profiled diamond tools.

Yet its extreme hardness makes it difficult to machine the diamond tool itself and prepare the precise geometry of its cutting edge. The mechanical properties of hard metals depend on the binder metal content which affects mainly hardness and wear resistance as well as on the average grain size which is responsible for the flexural strength fig.
