摘要

Novel process technologies of thermal nanoparticles coating and microlines patterning were newly developed to fabricate fine ceramics layers and geometrical intermetallics patterns successfully for mechanical property modulations of practical alloys substrates. Nanometer sized alumina particles were dispersed into acrylic liquid resins, and the obtained slurry materials were sputtered by using compressed air. The slurry mists could blow into the arc plasma with argon gas spraying. On stainless steels substrates, the fine surface layers with high wear resistance were formed. In cross sectional microstructures of the coated layers, micromater sized cracks or pores were not observed. Subsequently, photo sensitive urethane resin including pure copper particles was spread on a pure aluminum plate. Fractal networks with self similar arrangements were drawn by single stroke scanning of an ultra violet laser beam. Micro patterns composed of copper aluminides were created through heat treatments. Microstructures and composite distributions in the formed composite lines were observed by a scanning electron microscope and energy dispersive X-ray spectroscopy, respectively. Measured mechanical properties by tensile tests were compared with simulated and visualized results by finite element method.
