Solid particle erosion–corrosion behaviour of a novel HVOF nickel aluminium bronze coating for marine applications—correlation between mass loss and electrochemical measurements

Tribo-corrosion of coatings: a review

“…To understand the repassivation kinetics in such complex mechanical and electrochemical environments is not straightforward but some electrochemical techniques may be applicable. For example, electrochemical noise measurements have been used to investigate the interactions between erosion and corrosion of HVOF aluminium, aluminium bronze and aluminium-silicon coatings, Tan [61] and Wood [62]. Although perturbations (noise) on the corrosion current measurements represented multiple sand particle impacts, valuable insights into the mass transport and repassivation kinetics occurring under erosion-corrosion were obtained.…”

Effect of heat treatment on microstructure evolution and erosion–corrosion behavior of a nickel–aluminum bronze alloy in chloride solution

“…This protective film is generally vulnerable to high velocity fluid flow along with solid particle impingement, which usually emerges in propulsion systems. Therefore, surface technologies, such as thermally spray coatings, have been developed for improved erosion-corrosion performance of the NAB in various environments [11][12][13][14]. However, the coating performance is often unsatisfactory due to the presence of micro-defects and micro-cracks in the coating, reducing its integrity and thus the protective ability to the NAB substrate.…”

Erosion–corrosion resistance of engineering materials in various test conditions

“…Amongst these rigs are slurry pot erosion tester [4][5][6][7][8][9], jet impingement rig [10][11][12][13][14], Coriolis erosion tester [15][16][17], pipe flow loop [18,19] and rotating cylinder apparatus [20][21][22]. Each rig has its advantages and disadvantages in terms of ease of usage, cost, ease of maintenance and control of test parameters.…”
