Seawater corrosion behavior of laser surface modified Inconel 625 alloy

Influence of laser alloying with boron and niobium on microstructure and properties of Nimonic 80A-alloy

“…Nickel and its alloys were also modified using laser beam [34][35][36][37][38][39][40]. Laser surface alloying caused changes in the chemical composition, microstructure and properties.…”

“…Nimonic 80-alloy was laser-alloyed with Si and Al [36,37]. Laser alloying of Inconel 625-alloy with hard carbides (TiC and WC) was also studied [38]. Aluminum and molybdenum were used as an alloying material of pure nickel using laser processing [39].…”

In-situ synthesis of a carbide reinforced steel matrix surface nanocomposite by laser melt injection technology and subsequent heat treatment

“…Laser Melt Injection (LMI) technology has been known since the 1980s [1] and has been used to improve surface characteristics of metallic alloys, such as steels [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], aluminum [18][19][20][21][22][23][24][25][26][27][28], titanium [27,[29][30][31][32][33][34][35][36][37][38][39], nickel [40][41][42] and magnesium [43]. During LMI hard particles with the size range of 10-100 µm are blown by a gas stream into a liquid metallic pool, melted by a fast moving laser beam.…”

Stress corrosion cracking sealing in overlaying of Inconel 182 by laser surface melting

“…LSM can be applied to repair the tubes degraded by IGC/IGSCC during the normal operation of the nuclear power plants, since the laser beam can easily be directed to the failed parts through a beam transmission system such as an optical fiber. Much research on the improvement of SCC resistance of Inconel 600 by the LSM process has been done [3][4][5][6][7][8][9][10], while a few papers on the repair procedure by LSM are available.…”
