(PDF) Cavitation erosion corrosion behavior of some

Mar 27, 2019 · Cavitation erosion is still a phenomenon which causes severe damages to hydraulic turbine runners. A lot of effort has been deployed in the scientific community to understand the (PDF) Corrosion and Cavitation Erosion Behaviors of The microstructure, corrosion, and cavitation erosion behaviors of the thermo-mechanically affected zone (TMAZ) in a friction stir processed Ni-Al bronze were investigated.

Cavitation erosion behavior and surface morphology

Cavitation erosion behavior and surface morphology evolution of 316LN austenitic stainless steel in 3.5% NaCl Solution Zhisong Shao 1, Shuaixing Wang,*, However, in addition to pitting, intergranular corrosion and SCC, the 316LN SS elbow used in the AP1000 nuclear power plant may also suffer from cavitation erosion at the bends and stenosis Corrosion and Cavitation Erosion Behaviors of Friction weld nugget zone, and the top had the highest pitting corrosion resistance.17 NAB is widely used in marine environments be-cause of its high corrosion and cavitation erosion re-sistance.18-19 It is one of the main materials for ship propellers. Since the propeller rotates at high speed in seawater, it suffers both corrosion and cavitation erosion. Effects of Surface Treatment on the Cavitation Erosion Apr 15, 2020 · In principle, the deterioration of a surface due to cavitation erosioncorrosion starts in a sudden surge of bubbles, which final result in deformation and eventually damage of the protective film. As a result, surging of bubbles would expedite corrosion, leading to pitting.

Journal of Chinese Society for Corrosion and protection

The electrochemical results showed that under the action of cavitation erosion the free corrosion potential of Mn-brass and MAB shifted to a more positively value, in the contrary, a negative value for NAB. Due to the action of cavitation erosion, the free corrosion current density increased by an order of magnitude for the three copper alloys.Cavitation erosion and corrosion behaviour of laser Oct 01, 2000 · The laser alloyed specimens for cavitation erosion and electrochemical corrosion tests were cut into squares of dimensions 13×13 mm. The specimens were polished to constant surface roughness using 1 m diamond paste and then cleaned, degreased, dried, and weighed before and after each subsequent cavitation erosion and pitting corrosion test.
