The wettability of silicon carbide by liquid aluminium: the effect of free silicon in the carbide and of magnesium, silicon and copper alloy additions to the aluminium

Influence of SiC surface polarity on the wettability and reactivity in an Al/SiC system

“…Much smaller contact angles reported in Ref. [18] were attributed to the presence of 18 wt.% free silicon in the reactionbonded SiC substrates.…”

“…1. Equilibrium contact angles for the Al/SiC system as a function of temperature reported in literature [8,[11][12][13][14][15][16][17][18][19]. SC, single crystalline SiC; S, sintered polycrystalline SiC; RB, reaction bonded polycrystalline SiC.…”

Multiphysics Simulation and Experimental Investigation of Aluminum Wettability on a Titanium Substrate for Laser Welding-Brazing Process

“…While the interaction between the liquid and its vapour is well known in our case, the values of the two other surface tensions could not easily be found in the literature. Nevertheless, this parameter is very easy to observe experimentally and the few works found in the literature indicate a linear decrease of the angle with the temperature [21,22].…”

Effect of nanosized SiC particles addition to CP Al and Al–Mg powders on their compaction behavior

“…In those studies, it was reported that the addition of at least 1 wt.% Mg to Al was required for the embedding of SiC nanoparticles into the matrix alloy. These results were attributed to the effect of Mg as an enhancive wetting agent for nanosized SiC particles [34]. However, the processing of CP Al/nano-SiC powders via the IPM method resulted in the fabrication of a mixture of free SiC nanoparticles or their agglomerates accompanied with monolithic CP Al powders.…”
