  • The Pitting corrosion book covers recent research challenges and various accomplishments in the field of corrosion. The book is a proven record of excellent scientific achievements in the field of pitting corrosion. Pitting corrosion involves local dissolution followed by the formation of cavities on metals surfaces coated with a passive film, when exposed to an aqueous solution containing aggressive anions, such as chloride and sulfate. Pitting is one of the most destructive forms of corrosion, as it causes potential failure of metals and alloys due to perforation/penetration....

  • The classic theories are based on the scientific and rational view of the companies, of management systems and on the scientific organisation of the work, premises under which it is assumed that employees are passive subjects whose performance may be totally controlled by formal mechanisms.

  • Chemical structure of -aminonaphthalene (ANa) allows to deal with its electrochemical polymerisation, analogously as for aniline. To determine the oxidation potentials of ANa, the polymerisation has been realised on Pt electrode using cyclic polarisation. It was found that in sulphuric acid 0.5 M the first oxidation starts at 620 mV/SCE with the peak potential at 760 mV, and the second oxidation at 890 mV/SCE with the peak potential at 1230 mV. The PANa film development decreases the current peaks meaning a reduction of polymerisation rate.
