Cavitation wear of untreated and laser-processed hardfaced coatings

Cavitation erosion of some laser-produced iron-base corrosion-resistant alloys

“…One possible way of the material protection may consists in manufacturing the surface layer of high erosion resistance. Results of numerous work proved that alloying, cladding, melting or rapid heating of ferrous alloys by laser beam was an effective method leading to an increase in their cavitation resistance [1][2][3][4][5][6][7][8]. However, the problem of protecting hydraulic machine surfaces still remains in many cases unresolved, because the erosion of different iron-base metals is very differentiated [9] and the material resistance to cavitation action also depends on intensity of the loading and type of the impingement.…”

Laser Surface Alloying of Ni-Co Electroplated Low Carbon Steel

“…LSA of aluminium plated Ni-P has also been carried out [9]. The cavitations erosion resistance and microstructure development of Co-and Ni-based alloy powder coating on mild steel has been reported with emphasis on the effect of laser remelting of flame-sprayed coating [10,11]. Most of the work involves LSA of Ni, Ni-P, duplex layers of Ni and Cr, however, to the best of our knowledge, no study have ever been presented with electroplated Ni-Co alloy (91.5% Ni and 8.5% Co) on steel AISI 1010.…”

Cavitation erosion of steels processed by CO2 laser beams of various parameters

“…[1][2][3][4][5][6][7][8][9]). The obtained level of protection effectiveness depends on the properties of created surface layer of the material and hence, on the method and parameters of its processing.…”
