| Research Abstract |
Friction surfacing using alumina particles dispersed aluminum alloy composite to make a plate a high functionality. It was examined which made the deposit disperse high hardness particles on the friction surfacing process. The deposit which had high anti-wear was made on 5052 aluminum alloy plate by friction surfacing doing particles dispersed aluminum alloy composite, and it could get the friction surfaced material which had an expensive anti-wear compared with base metal. Friction surfacing was done using the drilled aluminum alloy bar which was filled with the alumina particles. It became possible that it got the deposit that alumina particles of high hardness dispersed on the plate by friction surfacing without metal matrix composite. As for high functionality of the plate by the friction stir welding, it paid attention to structure due to the stirring in the friction stir process becoming fine grain structures. The effect of grain to fine by the friction stir processing was confirmed. It tried the dispersed of the high hardness particles in the plate by friction stir processing, and groove processing was done in the plate, and filled with the alumina particles. The dispersion of the high hardness particles was possible in the plate by the friction stir processing. A state of distribution of the alumina particles in the plate varied in the shape of a rotation tool to use. The dispersion of alumina particles is the best of the case of the screw type rotational tool was used. But, there is a little amount of dispersed of alumina particles on the surface of plate. In case of using a taper type rotational tool, the amount of dispersed of alumina particles is a little compared using a screw type rotational tool, but there were many comparatively on the surface of the plate and it dispersed uniformly.
