Objective This project work has demonstrated that the high speed tool steels, with copper phosphorus as a sintering aid, can be sintered to high density and high strength at temperatures of less than 1150 C. These materials form a suitable base for the addition of carbides, oxides, etc, for the improvement of wear properties in components.INCREASED WEAR RESISTANCE OF CONVENTIONALLY SINTERED COMPONENTS, ESPECIALLY FOR THE AUTOMAOTIVE INDUSTRY, IS REQUIRED AND SEVERAL APPROACHES ARE THE SUBJECT OF RESEARCH AND DEVELOPMENT.THIS PROJECT INVOLVES THE UTILISATION OF METAL COATED (NI OR CO WITH MINOR OTHER ADDITIONS) CHEAP CERAMIC POWDERS (SIC, TIC, AL2O3, CR23 C6, TIN, SI3N4, TIB2 AND VC) FOR INCORPORATION IN FE-BASED MATRICES, BOTH HOGH-SPEED STEEL AND TRADITIONAL FE-CU, FE-NI TYPES.CONCURRENT OBJECTIVES ARE LOW SINTERING TEMPERATURES, BELOW 1180 CELSIUS DEGREES, HIGH DENSITY, STRENGTH, TOUGHNESS, AND CORROSION RESISTANCE.THE EXISTENCE OF A SUITABLE METAL LAYER ON THE CERAMIC POWDER SHOULD MINIMISE DIE WEAR, IMPROVE SINTERING CHARACTERISTICS OF THE CERAMIC/METAL COMPOSITE AND INHIBIT DISSOLUTION OF THE CERAMIC IN THE METAL, WHICH WOULD HAPPEN AT ABOUT 1100 CELSIUS DEGREES FOR SIC AND FE. SEVERAL SYSTEMS, INVOLVING BOTH HIGH TEMPERATURE SOLID STATE AND LOWER TEMPERATURE LIQUID PHASE SINTERING, THROUGH THE INCORPORATION OF CU-P POWDER ADDITIONS, WILL BE INITIALLY INVESTIGATED AND PROMISING CANDIDATES CHOSEN FOR FURTHER EVALUATION AND PROTOTYPE FABRICATION AND TESTING.
