Wettability of Brazing Filler Metals on Copper and Copper Alloys
The possibility of alloying can not be avoided at the interface between molten brazing filler metal and base metal in brazing, so the wettability of brazing filler metal can not be easily explained theoretically. We used the original apparatus for wettability test and investigated the relation between the wettability of brazing filler metals of Ag-P-Cu and Ag-Cu-Zn-Cd systems on copper and the ...
متن کاملPromotion of the Cupellation Method for Accurate Determination of Gold Alloy’s Karat Containing Platinum-Group Metals
The main standard method for gold karat determination is the cupellation method. However, this method is not sufficiently accurate to determine gold karat in the presence of insoluble Platinum–Group Metals (PGMs), such as Ir, Ru, and Rh. In this study, for the first time, a complementary method that can be used coupled with the reference cupellation method is presented for the high...
متن کاملVacuum Brazing of Zirconium-Based Alloy and 321 Stainless Steel Using Titanium Based Filler Metal
Both Zirconium-based alloys and 321stainless steel are widely used as engineering alloys due to their good mechanical properties. Conventional fusion welding techniques for Zr alloys and stainless steel are not feasible due to the formation of brittle intermetallic compounds such as (Zr3Fe, ZrFe2 and Zr2Fe) and corrosion cracking. Brazing is one of the most wide...
متن کاملThe Microstructural Evolution of Vacuum Brazed 1Cr18Ni9Ti Using Various Filler Metals
The microstructures and weldability of a brazed joint of 1Cr18Ni9Ti austenitic stainless steel with BNi-2, BNi82CrSiBFe and BMn50NiCuCrCo filler metals in vacuum were investigated. It can be observed that an interdiffusion region existed between the filler metal and the base metal for the brazed joint of Ni-based filler metals. The width of the interdiffusion region was about 10 μm, and the mic...
متن کاملMicrobial Treatment of Cyanide and Heavy Metals Containing Waste Water from Gold Mining
Cyanide-bearing waste water from'gold mining is usually decontaminated by oxidation so that the dissolved metals are precipitated as hydroxides. The disadvantages of this method are high consumption of chemicals and the formation and liberation of toxic compounds. Various bacterial and fungal strains capable of degrading cyanides or having a high potential for metal adsorption were isolated fro...
