Semisolid Process

Metal ceramic composite are adding ceramic particle powder to metal, also called powder dispersion reinforced materials, Its unique properties with extensive use value. But how to produce the metal ceramic composite is the main diffculty of the technology. In the last the method of the mixing are mechanical mixing method ,electromagnetic stirring and so on .The shortcomings of mechanical mixing method is clunky, difficult operation and low efficiency. The problem of the electromagnetic stirring method is its large equipment investment and its complex device. The paper researched a new device to produced metal ceramic composite in the semisolid process which advangtage is self-quantitative ,uniform mixing,save energy and environmental protection.This device was designed in sample full consideration of the mixing process may. As much as possible to avoid cracks. As to the sealed containers to consider the nitrogen let liquid to prevent oxidation and reduce the impurity intervention; Another auxiliary handle design also to make the experiment more convenient and accurate Indeed, etc. These advantages are the practicability for device, and provide a guarantee for the production metal ceramic composite.

The metal ceramic coating of TiAl (CN) by nitrogen-arc cladding technology was produced on the surface of 45#steel.The phase composition of coating was analyzed with X-ray diffractometer; The bonding state and microstructure were observed with scanning electron microscope; The microhardness was examined and the wear resistance of the metal ceramic coating compared with that of 60Si2Mn steel treated by quenching and tempering was tested by abrasive tester as well. The results indicated that the TiAl (CN) ceramic particle synthesized in-situ is distributed dispersively in the cladding and the size is under 3 um. The excellent bonding between the coating and 45# steel substrate is strengthened by the strong metallurgical interface; the coating is uniform and continuous. The maximum microhardness of cladding is HV0.21820 and the abrasive performance is better than 60Si2Mn steel treated by quenching and tempering. The simulation test results showed that the cladding is good, and can be used to the repair and remanufacture for wearable parts of stubble-cleaning cutter.
