Abstract:
This study shows the results of mechanical properties (hardness, toughness, TRS), oxidation behavior against high temperature and wear resistance of composite materials based on a ceramic phase –Ti(C,N) or WC– and a metal binder (Fe15Ni10Cr). These hard metals were produced through a powder metallurgy process that included mechanical milling, uniaxial pressing, and sinter-HIP. Standardized cylindrical specimens were used for TRS tests, and oxidation tests were conducted on broken specimens in static air at temperatures up to 1000 ºC. Wear behavior was analyzed through reciprocal sliding tests using WC-Co balls as counter material with loads up to 30 N and test times up to 150 min. This study recorded the friction coefficient during and after the tests, the mass variation, the width, and depth of the wear tracks analyzed by an optical profilometer.
