“…On the other hand, the compounds have shown to be suceptible to enviromental embrittlement (specifically hydrogen embrittlement) at ambient temperature in moisture in air and hydrogen gas (Kaneno et al,2011 ;Takasugi et al, 1993a ;Takasugi et al, 1993b). The addition of boron of Ni3(Si,Ti) was to suppres enviromental embrittlement (Takasugi et al, 1995), although the intergranular attack were observed for this as-homogenized Ni3(Si,Ti) compound (Priyotomo et al,2011) and Ni3(Si,Ti) compound after thermomechanical process (Priyotomo et al,2013) in acidic solutions, which took place by boron segregation at grain boundaries.…”

The pitting corrosion of Ni3(Si,Ti) intermetallic compound was investigated as function of chloride concentration by using electrochemical method and scanning electron microscope in sodium chloride solutions at 293 K. In addition, the pitting corrosion of type C276 alloy was also studied under the same experimental condition for comparison. The pitting potential obtained for the intermetallic compound decreased with increasing chloride concentration. The specific pitting potential and pitting potential of Ni3(Si,Ti) were lower than those of C276 alloy, which means that the pitting corrosion resistance of C276 alloy was higher than that of Ni3(Si,Ti).

The corrosion behavior of Ni3(Si,Ti) + 2Mo intermetallic compound (L12 and (L12 + Niss) mixture region) has been investigated using an immersion test, polarization method and surface analytical method (scanning electron microscope and energydispersive X-Ray spectrometry) in 0.5 kmol/m 3 hydrochloric acid (HCl) solution at 303 K. In addition, the results obtained were compared to those of the L12 single-phase Ni3(Si,Ti) intermetallic compound and C 276 alloy. It was found that Ni3(Si,Ti) + 2Mo had the preferential dissolution of L12 with a lower Mo concentration compared to (L12 + Niss) mixture region. From the immersion test and polarization curves, Ni3(Si,Ti) + 2Mo and C276 showed the lowest corrosion resistance and the highest corrosion resistance in the solution, respectively. From this work, It implied that unlike C276, Ni3(Si,Ti) +2Mo intermetallic compound was difficult to form a stable passive film in HCl solution as well as Ni3(Si,Ti) in the same solution.
