Three-body Abrasive Wear Resistance of Iron Matrix Composites Reinforced with Ceramic Particles
Pure aluminum oxide (A1203), ZrO2 toughened Ai2O3(ZTA; 25-30% ZrO2) , and ZTA (55-60 % ZrO2) ceramic particles reinforced Cr25 matrix composites are successfully fabricated by the infiltration casting process.The volume frac tion of ceramic particles in the composites is 47-55 %.The interface structure between ceramic parti cles and the matrix was analyzed by digital probing microscopy and was found to be continuous mechan ical bonding.The wear behavior of the composites was studied by a three-body abrasive wear tester.ZTA (55-60 % ZrO2) reinforced Cr25 composite has excellent wear resistance which is approximately six times higher than that of the high chromium cast iron matrix.It is discovered that the wear mecha nism of composites is micro-cutting and fatigue stripping.A correlation exists between the wear re sistance of composites and the strength of ceramic particles.
