Abstract
In the present research a detailed effect of standoff distance water jet peening with the variation of jet presurre on the flat titanium alloy surface has been studied. During the experimentation, at a traverse speed of 30 mm/s accidently the change in standoff distance was encountered in the repeated test. Same treatment condition) which has been reported in this work. The frequency was f = 20 kHz at the pressure of p = 70 MPa with variation in standoff distance was increased from 20 mm up to 100 mm (with step distance of 20 mm ) during the treatment process. The change in microstructural was observed using scanning electron microscopy (SEM). The strengthening mechanism on the surface and subsurface region due to the plastic deformation phenomenon caused by the impact of the waterjet peening was evaluated by Vickers micro hardness test. The micro hardness test was conducted along the depth of the treated region to analyze the effects in the sub-surface layers by scanning the surface by optical Micro Prof FRT profile meter in order to analyze the erosion phenomenon with the variation of standoff distance and jet pressure during the treatment process. The results obtained indicates that the variation in standoff distance has a significant impact on the surface hardness number of the titanium alloy. The above observations elaborated the effect of standoff distance were better and effective of the applied technology for the surfac
