The effect of laser surface melting on the cavitation wear of grey cast iron in distilled and 3% salt waters

Fabrication of TiC-Reinforced Surface Layers on Ductile Cast Iron Substrate by Laser Surface Alloying

“…As a consequence, much emphasis has been early and currently placed on the improvement of wear performances of the working surface of machine parts made of the DCIs [6][7][8][9][10][11][12][13]. Considerable research has been devoted to laser surface modification methods, such as laser surface melting (LSM), alloying (LSA) and cladding (LSC) processes [14][15][16][17][18][19][20][21][22][23][24]. The LSA process is the most innovative approach to the enhancement of wear properties of the working surface of components made of different cast iron grades.…”

Electron beam surface melting of as cast and austempered ductile irons

“…It has been reported that with surface melting the graphite phase is eliminated and a harder and greatly refined ledeburitic microstructure is formed. As a result, surface melting greatly improves the wear resistance of cast irons [10]. Surface melting technique has been investigated and applied on various ferrous castings in automotive industries mainly to improve their wear resistance.…”

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.…”
