| Research Abstract |
The surface of high silicon aluminum alloy(high Si-Al Alloy) was machined by wet blast technique. The slurry, that is pure water contained with alumina particles with 1. 2μm in diameter by a concentration of 3 mass% is jetted on the high Si-Al alloy specimen. The impingement angle of the slurry was set from 45 to 90 degrees. As a result, the processed surface of high Si-Al alloy was classified into two types of topography. One is the surface with convex areas of Si, and the other is the surface with dimples of Si.
