Method of making an adhesive bond on the surface of a diamond

摘要

Method of producing an adhesive bond on a small surface of a diamond (8), for example for the cutting transducer for mechanically cut recording media such as a video disc or audio disc. The adhesive bond is made by fusing-on a layer (7) of a gold/tantalum alloy, using a further layer (1) of a metal from groups IVa, Va or VIa of the Periodic Table. <IMAGE>
