The consequences of corrosion are many and varied and the effects of these on the safe, reliable and efficient operation of equipment or structures are often more serious than the simple loss of a mass of metal. Failures of various kinds and the need for expensive replacements may occur even though the amount of metal destroyed is quite small. Some of the major harmful effects of corrosion can ...

Corrosion is recognized as an unavoidable phenomenon and steel, particularly carbon strongly susceptible to corrosion. damages cause serious material, energy, economic losses well negative impacts on the environment. As a result, research interest has been focused development of effective corrosion prevention strategies. However, some most commonly used inhibitors, such chromates pyridines, are...

A novel graphene-coated Ni electrode was developed in this investigation to improve corrosion resistance while unexpectedly enhancing the ammonia generation rate in the electrochemically induced urea to ammonia (eU2A) process, which is an electrochemical onsite ammonia generation method. The development of the electrode is crucial for the eU2A reactions since in the ammonia generation process, ...
