Cemented tungsten carbide substrate with enhanced surface to receive chemical vapor deposited diamond film and method of making same |
摘要 |
A carbide substrate including a binder prepared to receive a cutting material such as a diamond coating thereon. The substrate is immersed in an electrolyte solution with the substrate acting as the anode thereby providing for an electro-polished substrate surface. The electro-polished substrate surface is then etched to substantially remove the binder phase of the carbide substrate, the etching being to a depth of up to about 15 microns. The resulting surface is susceptible for receiving a coating of the diamond cutting material. |
