Abstract
The reliability of a braze joint formed between a diamond film and a tungsten carbide body is increased by use of a vanadium containing braze. The braze joint exhibits an average shear strength greater than about 40,000 pounds per square inch, (276 MPa) and the braze exhibits a contact angle with the diamond film of less than about 15.degree..
