ABSTRACT:
A diamond article, for example, a sheet-form diamond tool insert brazable in air. The diamond sheet has a dual layer coating, a WTi bonding layer and a protective braze compatible overcoat, such as a Ag overcoat. The interface between the WTi layer and the diamond substrate includes sufficient metal carbide component to provide adhesion. Once coated with the WTi layer and the protective overcoat, the dual-coated diamond insert may be air brazed to a tool substrate in a manufacturing environment using a standard braze without a vacuum furnace or special atmosphere. A method for manufacturing the diamond insert is also disclosed. The diamond insert is coated and heat treated in an oxygen- and nitrogen-free atmosphere to create metal carbide at the diamond-coating interface.
