摘要: Abstract In this work, self-lubricating Ti(C,N)-based cermets were prepared by solid carburization. The sintered wrapped carburizing agent and again at 1440 °C with different time. microstructure composition of studied. wear behavior containing graphite phase was also evaluated using a block-on-ring tribometer. results showed that the carbon content increased gradually in binder When time 3 h, got saturated phase. exceeded solubility binder, excessive precipitated formed Uniformly distributed clusters after carburization for 4 h. consisted flocked particles. With extended to 5 h, became large some them interlaced together. Besides, indicated volume loss half without due formation smooth tribofilm on worn surface cermets.
