Abstract The use of molten-salt–based energy production and storage systems requires high-temperature corrosion- creep-resistant structural materials. This study investigated the microstructure evolution corrosion characteristics Hastelloy N under working stress in a molten salt environment. Selective diffusion Cr at grain boundaries (GBs) degraded properties GBs, making them preferred location...

In order to study the dynamic mechanical properties at high temperature and strain rate [1] of Q245R steel after corrosion, electrochemical accelerated corrosion test by constant current method tensile [2] High Temperature Synchronous Hopkinson Tensile device were carried out. The results show that has obvious strengthening effect softening effect, under certain conditions, becomes main factor ...

For concrete bridge projects in marine environments, attention must be paid to the reinforcement corrosion problems caused by chloride intrusion. As kinds of functional admixtures, which can reduce the reinforcement corrosion rate, corrosion inhibitors are becoming very popular in China in new bridge projects. Corrosion inhibitors cover both inorganic and organic inhibitors. Nitrite is represen...

The effect of oil soluble commercial corrosion inhibitors (OSCI) on the growth of bacteria and its corrosion inhibition efficiency were investigated. Corrosion inhibition efficiency was studied by rotating cage test and the nature of biodegradation of corrosion inhibitor was also analyzed by using FTIR, NMR and GC-MS. This isolate has the capacity to degrade the aromatic and aliphatic hydrocarb...

The corrosion protection factor (c.p.f.) and the corrosion condition (cc.) are simple instruments for the study and evaluation of the contribution and efficiency of several methods of corrosion prevention and control. The application of c.p.f. and cc. to corrosion and prevention in agriculture in The Netherlands is considered in detail. Attention is paid to relations between c.p.f. and c.c., th...

This Laboratory Directed Research & Development (LDRD) project conducted in fiscal years 1996 and 1997 under case 3526.030 was devoted to the development of test structures and associated measurement methodology for assessing the reliability of plastic encapsulated microelectronic devices. The end goal was the conceptual specification of one or more Assembly Test Chips (ATCs) which could be use...

Corrosion significantly affects the structural behavior of members in a connection (i.e., thickness steel plates, preload force bolts, and friction factor plates). Safety assessment corroded frames beam-to-column connection, beams, or columns) has been major concern engineering. In this work, an experiment accelerated corrosion testing is carried out to obtain specimens connected with high-stre...

In this work, tribocorrosion performance of the High Power Impulse Magnetron Sputtering (HIPIMS) nitrided (F75) CoCrMo alloys was examined with help sliding wear corrosion experiments carried out in Hank's solution. Results indicate that under Open Circuit Potentials (OCP), both and untreated specimens exhibited near similar Sliding-Wear-Corrosion coefficient (KSWC) values (6.52 × 10−15 3.95 m3...

This Laboratory Directed Research & Development (EDRD) project conducted in fiscal years 1996 and 1997 under case 3526.030 was devoted to the development of test structures and associated measurement methodology for assessing the reliability of plastic encapsulated microelectronic devices. The end goal was the conceptual specification of one or more Assembly Test Chips (ATCs) which could be use...
