Element diamond coated tool corresponding substrate and method of making.

摘要

A tool includes a substrate of cemented carbide BASED TUNGSTEN CARBIDE AND DIAMOND COVER PLACED on the substrate. The substrate has two peaks KA1 and KA2 Diffraction CLASSIFIED INDEX BY PLANE (211) for the tungsten carbide X-ray diffraction. PEAKS SATISFACENLA RATIO L1 / L2 = 35 wherein L1 and L2 are the heights of the KA1 KA2 PEAKS AND MEASURED FROM A BASE OF A DEPRESSION AMONG TWO diffraction peaks. To manufacture TOOL, A GREEN COMKPACTO SINTERED IS FIRST TO PROVIDE A SUBSTRATE BASED ON Cemented Carbide tungsten carbide. SUBSEQUENTLY THE SUBSTRATE IS GROUNDED HEAT TREATED AND SUBSEQUENTLY at a temperature between 1000 CY 1600 C in a vacuum or in an atmosphere NO oxidizer. Thereafter, a deck of diamond is formed on the substrate by the method of vapor deposition.
