Effects of liquid droplet volume and impact frequency on the integrity of Alnalloy AW2014 exposed to subsonic speeds of pulsating water jets

Original language description

This study focuses on the analysis of the surface material integrity of the polished, rigid, solid surface of annaluminium alloy after periodical impingement of liquid droplets with variable volume and impact frequencyndistributions normal to the solid surface. The volume of water droplets was determined for the pressures of 20nand 40 MPa. By increasing the traverse speed of the ultrasonic pulsating water jet head with respect to thenstationary tested specimen, the number of water droplet impacts on one area was controlled in order to reach thenearly erosion stages. Also, for the comparative study, aluminum alloy was exposed to continuous water jet fornboth supply pressure 20 and 40 MPa with traverse speed of 1 mm/s over the material surface. Systematic testingnfocused on material integrity in the early erosion stages in the interval between the elastically deformed surfacenand material disintegration was conducted with the aid of microhardness measurements, X-ray analysis of stressnstate, and microstructural analysis by SEM. The motivation for carrying out this experiment was to verify theneffects of periodic drops on the integrity of the material and to identify the parameters leading to surfacenstrengthening without erosion as compared to continuous jet. Such surface treatments can improve fatigue life,nsimilarly to shot peening.
