Abstract
Microcrystalline diamond thin films were deposited on cemented tungste n carbide cutting tools by hot-filament chemical vapour deposition pro cess. The coatings deposited were irradiated with 50 MeV Si7+ ions upt o a dose of < 10(13) ions cm(-2). The adhesion and wear characteristic s of as-deposited and irradiated coatings were studied and it was foun d that irradiation induced increased adhesion of the coatings to the s ubstrate resulting in reduced coating failure during wear tests.
