Objective
The technical objective was to develop ion beam technology for the improvement of the wear and corrosion properties of machine tools.
The importance of ion beam dosage levels in direct ion implantation was established and increases in service life of up to 40% for machine tools have been found. The potential and scope of diamond like coatings (DLC) using ion beam assisted coating (IBAC) has been elucidated but found to be unsuitable for computer terminal control (CTC) tools. However, the results on alumina substrates are encouraging. The advantages claimed by the Japanese for IBAC deposited zirconium could not be repeated. Boron nitride coatings using IBAC techniques have been developed.
Industrial trials have shown significant improvements in machine tool wear.
THE PRINCIPAL OBJECTIVES ARE:
- TO DETERMINE THE EFFECTS OF NITROGEN ION IMPLANTATION ON THE SURFACE DURABILITIES OF CEMENTED TUNGSTEN CARBIDE (CTC) AND INDUSTRIAL HARD CERAMIC MATERIALS, E.G. SIALON AND ALUMINA, BY LABORATORY MICROHARDNESS AND SCRATCH TESTS;- TO ESTABLISH OPTIMUM TREATMENT CONDITIONS IN TERMS OF ION DOSE AND SAMPLE TEMPERATURE FURING IMPLANTATION;
- TO INVESTIGATE THE EFFECTS OF ION BEAM MIXING OF SELECTED POTENTIAL STRENGTHENING ELEMENTS, SUCH AS VANADIUM AND TITANIUM INTO COBALT AND TITANIUM, SILICON AND BORON INTO INDUSTRIAL HARD CERAMICS;
- TO EMPLOY ADVANCED SURFACE ANALYSIS TECHNIQUES AND THEORETICAL STUDIES TO BETTER UNDERSTAND THE STRUCTURAL CHANGES INDUCED BY ION IMPLANTATION;- TO OBTAIN DESIGN PARAMETERS FOR NEW ION IMPLANTATION HARDWARE CAPABLE OF MEETING ALL MAJOR REQUIREMENTS FOR TREATING CTC AND CERAMIC INDUSTRIAL TOOLS AND COMPONENTS;
- TO CONDUCT MONITORED INDUSTRIAL TRIALS OF SELECTED CTC AND CERAMIC TOOLS TO VERIFY LABORATORY RESULTS AND ESTABLISH COMMERCIAL/INDUSTRIAL BENEFITS OF ION IMPLANTATION.
