| Outline of Final Research Achievements |
In this study, the effects of injection angle on the textured surface were investigated. The test slurry was pure water containing angular alumina particles 1.2 μm in diameter. The injection angle was set to 30° or 90°. At an injection angle of 30°, a surface with protruded silicon was produced. At an injection angle of 90°, the surface with dimpled silicon was produced.
And, the friction behavior of high silicon aluminum alloy with the surface texture was investigated using a ball (SUJ2)-on-plate reciprocating friction tester. Surfaces with protruded Si (injection angle of 30°) were shown to have low friction. Especially, surfaces with protrusion height ≧ 0.88 μm and protrusion area ≧ 9.5% were effective in maintaining low friction.
