Notes:
The TiC particles are selected as reinforced phase and the Hadfield steel as matrix. The powdermetallurgy liquid phase sintering technique is adopted to fabricate TiC particles reinforced Hadfield steelmatrix composites. The effects of elements Mo and Ni on the performance of the composites were studied.The impact wear tester is adopted to investigate the wear-resistant property of the composites under thedifferent impact loads. Adding Mo can improve the interfacial bonding between the Hadfield steel andTiC, and the best adding ratio between Mo and TiC is 1:3.68. Adding 2%(vol.%)Ni can significantlyimprove the density and hardness of the composites. The experiment results of impact wear tests showthat under the condition of low and middling loads, the composites display the best wear-resistantproperties, moreover, the more TiC content is, the better wear-resistance property is. Under 2.0J impactenergy, the wear resistance of the composite containing 40%(vol.%) TiC is 1.3 times of Hadfield steel
