The corrosion behaviour of the intermetallic compounds Ni3(Si,Ti) (L12: single phase), has been investigated using an immersion test, polarization method, scanning electron microscope in 0.5 kmol/m3 H2SO4 solution at 303 K. Moreover, the corrosion behaviour of austenitic stainles... |
Ayende; Rustandi, Andi; Soedarsono, Johny Wahyuadi; Priadi, Dedi; Sulistijono; Suprapta, Dewa Ngurah; Priyotomo, Gadang; Bakri, Ridla, 2018, "Effects of Purple Sweet Potato Extract Addition in Ascorbic Acid Inhibitor to Corrosion Rate of API 5L Steel in 3.5% NaCl Environment", https://hdl.handle.net/20.500.12690/RIN/ZMMI2A, RIN Dataverse, V1
Using vitamin C or ascorbic acid as corrosion inhibitor has several weakness. In its liquid form ascorbic acid is easily oxidized and its anti oxidant properties unstable due to heat, light, oxidizer, dissolved oxygen and heavy metals. Purple sweet potato (ipomoea batatas L) with... |
Priyotomo, Gadang; Wagle, Sanat; Okitsu, Kenji; Iwase, Akihiro; Kaneno, Yasuyuki; Nishimura, Rokuro; Takasugi, Takayuki, 2018, "The Environment-Induced Cracking of As-Cold Rolled Ni3(Si,Ti) and Ni3(Si,Ti) with 2Mo in Sodium Chloride Solutions", https://hdl.handle.net/20.500.12690/RIN/60J7NR, RIN Dataverse, V2
The environment-induced cracking (EIC) of as cold-rolled Ni3(Si,Ti) and Ni3(Si,Ti) with 2Mo has been investigated as functions of applied stress, chloride ion concentration, test temperature, and pH by using a constant load method in NaCl solutions. The EIC susceptibility of both... |
