並列タイトル等Formulation of Cavitation Erosion Including Deceleration Stage
一般注記Cavitation erosion tests were carried out by using vibratory apparatus to obtain MDE (Mean Depth of Erosion) and MDER (MDE Rate) curves for pure aluminum and aluminum-base alloys. The relation between the surface profile and impact load of cavitation was studied. Since aluminum alloys are very soft materials, the surface roughness increases with exposure time to cavitation. The impact loads on the specimen surface decreases with increased roughness, and the deceleration stage of MDER curves appears. It was concluded that the erosion rate d with exposure time can be expressed by four parameters α, β, c, and k in the following equation. d=(α/β){1/[1+(α/β)ce^<-αt>+kt]}
