Different methods of measuring synergy between cavitation erosion and corrosion for nickel aluminium bronze in 3.5% NaCl solution

Synergistic effects in hydrodynamic cavitation abrasive finishing for internal surface-finish enhancement of additive-manufactured components

“…Such impacts are a result of acceleration due to cavitation implosion (not noticed in pure cavitation and pure abrasion conditions). The findings are in good agreement with the observations from other investigations [51][52][53]. The positive synergistic effects contribute to a comprehensive removal of the surface asperities, resulting in a smooth and uniform surface finish.…”

In situ measurement of cavitation damage from single bubble collapse using high-speed chronoamperometry

“…Polarization method and electrochemical impedance spectrometry (EIS) are the two most common electrochemical methods in the corrosion studies. These two methods have been widely used to quantify the effect of cavitation erosion on corrosion and vice versa [7] , [8] , [9] , [10] , [11] , [12] . However, insensitivity to high-speed short-time changes on the surface, makes these two methods not suitable for the study of cavitation damage under single bubble collapse which occurs in microsecond time-scales.…”

Fabrication of MnCuNiFe–CuAlNiFeMn Gradient Alloy by Laser Engineering Net Shaping System

“…Mn–Cu alloy was once regarded as an ideal material for propeller damping, shock absorption, and noise reduction due to its excellent damping and mechanical properties [ 11 , 12 , 13 ]; however, due to its severe shrinkage porosity and poor stress corrosion and corrosion fatigue resistance, Mn–Cu alloy still faces challenges for application in the field of propeller manufacturing [ 12 , 14 ]. Current marine propeller materials are still mainly nickel–aluminum bronze (NAB) and composite materials [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ]; Mn–Cu damping alloys have not been widely used. In order to solve the above problems, researchers used traditional sintering [ 22 ] or cumulative rolling [ 23 ] methods to prepare gradient composites.…”
