This study establishes the ability of hydrate formation to initiate internal corrosions along natural gas pipelines. The identified corrosion types, which are cavitations, erosion and corrosions by chemical reactions, are capable to individually or collectively initiate pitting and stress cracking corrosions which are also dangerous to gas pipelines. The impacts of these corrosion types are cla...

The lithium metal anode is essential for next-generation high-energy-density rechargeable Li-metal batteries. Although extensive studies have been performed to prolong the cycle life of batteries, calendar life, which associates with chemical corrosion Li in liquid electrolytes, has not quantitatively understood. Here, by combing titration gas chromatography method and cryogenic focused ion bea...

in the diesel engine exhaust gas recirculation (egr) components, valve and connecting pipes are the critical components and fails often during new engine development. these components are important for meeting nox emissions norms. therefore design of these components should remain robust. but the challenge in design is compact packaging of complete egr components on the engine consequently vibr...

4. Neutron and X-ray Tomography in Non-Destructive Testing (NDT): A new complex neutron-, gamma-, and X-ray three-dimensional computer tomography system suitable for experimental and industrial applications has been built at 10-MW Budapest research reactor site. A number of objects were investigated and tomographic projections were made. We study the optimal preprocessing steps and the optimal ...

The objective of this work is to evaluate the corrosion behaviour nanographene oxide reinforced aluminium (Al/GO) metal matrix composites with different immersion time periods using technique. Al/GO were fabricated by ultrasonic gravitational stir casting process. corrosions evaluated a scanning electron microscope. experimental results revealed that rate decreased and weight losses increased i...
