Corrosion behavior of Al–Si–Cu–(Sn, Zn) brazing filler metals

Effect of process conditions on the evolution of microstructure and mechanical properties of AA3003 vacuum furnace brazing joints

“…In addition, it is possible that the sample would not mechanically stand the thermal exposure circumstances during brazing in the furnace. Therefore, introduction of novel low-melting-point filler metals and wise application of phase diagram calculations seem to be a necessary step for having sound Al brazed joints for industrial applications [18].…”

“…The direct and indirect effects of rare earth elements on heat resistance, formability and shear strength of final products have been studied as well [20]. Moreover, addition of copper and nickel to the conventionally used Al-Si filler metals can decrease the melting point of the filler metal and can be considered as another extensive research field in this context [18,21,22]. It should be noted that development of low melting point filler metals by different approaches have been the purpose of many other related investigations regarding vacuum brazing of Al alloys [23].…”

“…The development of novel filler metals with introduction of germanium [19], zinc [24] or tin into conventional Al-Si or low melting point Al-Si-Cu alloys have also been studied taking both mechanical properties and corrosion resistance of joints into account. However, some difficulties such as high cost of Ge supply and relatively high vapor pressure of Zn together with lower corrosion resistance of these doped fillers currently make their applications unreasonable in Al vacuum brazing process [18].…”

Joints Properties of Aluminum Foams/Aluminum Plate by Transient Liquid Phase Bonding Process

“…However, brazing also has many limitations. Due to the small depth of diffusion, harmful phases (intermetallic compounds, eutectic structures) will be concentrated in the joint region, severely reducing the joint performance [3][4][5]. Wang Hui [6] et al used Al-Si solder to weld aluminum foams in a nitrogen atmosphere.…”

Computational and Experimental Studies on the Inhibitive Effects of <i>Newbouldia laevis</i> Extract and Magnetic Fields on Copper Corrosion in Aqueous Acidic Media

“…The need to mitigate or control the degradation of copper metals exposed to aggressive conditions has been a subject of study and has attracted many researchers and various inhibitors have been under investigation. These include inorganic inhibitors [2], organic inhibitors of azole derivatives [3][4][5][6][7][8][9][10], amine [11][12][13][14], amino acid [15 -16] and green organic inhibitors [17][18]. The inhibitive actions of the various organic molecules and compounds are favoured by the various organic heteroatoms of nitrogen, sulphur, phospurous, and oxygen in molecules and multiple of bonds or aromatic rings in their structures [1,19,20].…”
