Vacuum brazing of TiB2 cermet to TiAl-based alloys using Ag-Cu-Zn filler metalLI Zhuo-ran(李卓然), FENG Ji-cai(冯吉才), CAO Jian(曹 健)(State Key Laboratory of Advanced Welding Production Technology, Harbin Institute of Technology, Harbin 150001, China)Abstract:Vacuum brazing of TiB2 cermet to TiAl-based alloy was carried out at 1223K for 5-30min using Ag-Cu-Zn filler metal. The microstructural analyses......
of a 100 mm diameter cup-shaped inert anode of cermet, which consisted of 17% (mass fraction) metal Ni and 83% ceramic (10NiO-90NiFe2O4), was evaluated in a laboratory electrolysis cell. It was the first... contamination of anode constituents vs electrolysis time for cermet electrodes After electrolysis, the current efficiency calculated based on the metal aluminum recovered at cathode is 60.81%. In the cell......
other and it increases with increasing temperature and content of metal Cu. At 960 ℃, the electrical conductivity of cermet increases from 2.88 to 82.65 S/cm with the content of metal Cu increasing from... by Alcoa, the reason for the determination of the content of metal Cu was not explained[13]. In this study, 10NiO-NiFe2O4 based cermet inert anodes with Cu content of 0, 5%, 10%, 15% and 20%(mass......

-undoped material sinter at 1 250 ℃ (96.70%). For the 2.0%CaO- Cu/(NiFe2O4-10NiO) cermet, when the mass fraction of metal Cu increases from 5% to 17%, the relative densities are approximate, being 97.63% and 95.05% respectively. Therefore, CaO is a good sintering agent for Cu/(NiFe2O4-10NiO) cermet. It can decrease sintering temperature and prevent the metal Cu from outflowing while the relative......

The filler is required to be capable of accommodating their chemical and physical incompatibility... that of other metal phases. Therefore, the fracture propagation was originated in Ti–Cu IMCs interface, and then spreaded to the TiC cermet in a typical brittle fracture manner, when exerting an external shear......
