Dilution of molybdenum on aluminum during laser surface alloying

Effect of high dilution on the in situ synthesis of Ni–Zr/Zr–Si(B, C) reinforced composite coating on zirconium alloy substrate by laser cladding

“…specific substrate material into account [11][12][13]. Self-fluxing Ni-Cr-B-Si powder has been widely cladded on steel substrates [14], aluminum substrate [15] and titanium substrate [16,17].…”

Preparation, microstructural evolution and properties of Ni–Zr intermetallic/Zr–Si ceramic reinforced composite coatings on zirconium alloy by laser cladding

“…When adopting high power laser, it should be taken into account that the melting of substrate causes diffusion and redistribution of alloying elements from the bottom to the top of coatings [11]. The redistribution of transition metal zirconium element has a correlation with the dilution of coatings and contributes to the formation of multiphase reinforcements within the matrix of coatings.…”

“…A C C E P T E D ACCEPTED MANUSCRIPT 11 as to further explore the underlying wear mechanism of intermetallics/ceramics reinforced coatings.…”

“…Therefore, different surface enhanced approaches, including electrodeposition [3], sputtering [4], ion implantation [5][6][7], micro-arc oxidation [8][9][10], laser surface alloying [11][12][13] and laser cladding [14][15][16][17][18][19][20], have attracted people's attention and have been attempted to repair the worn surface of components. The laser cladding is one of the most promising surface technologies because of metallurgical bonding between coating and substrate, lower content of oxides and porosity, as well as high efficiency [21][22][23].…”

Effect of pulsed Nd:YAG laser re-melting on chromium surface alloyed AA6061-T6 aluminum

“…So far, alloying elements which have been examined for surface alloying of aluminum are nickel [11], silicon [12,13], chromium [14,15], copper [16], iron [17], and molybdenum [18,19]. Several researchers have used rapid solidification techniques (such as melt spinning and atomization) to fabricate Al-Cr alloys [20][21][22][23][24].…”
