dc.description.abstract |
Metal matrix composite layers were formed on an aluminium substrate by means of laser surface alloying method. Aluminium 1200 was used as a host material and TiC particles were used as the reinforcement. The microstructure of the modified layer consisted of the hard particles uniformly distributed in the host metal matrix. A strong bond between the particles and matrix was formed in the modified layer. A Rofin Nd: YAG laser was used for injecting the ceramic powder into the substrate. In these experiments the laser power was varied from 3 to 4.0 kW, the laser scan speed was varied from 0.8 to 2.0 m/min. The powder feed rate was varied from 2 to 5 g/min. The structural characterisation of the metal matrix composite included X-ray diffraction (XRD), optical and scanning electron microscope (SEM) as well as microhardness measurements. The microhardness of the layers increased from 20 HV to 350 HV. This represented a significant improvement of the surface properties compared to the base metal. |
