Laser cladding of Ni50Cr: A parametric and dilution study (2016)
Presentation / Conference Contribution
Song, B., Hussain, T., & Voisey, K. T. (2016, September). Laser cladding of Ni50Cr: A parametric and dilution study. Presented at International Conference on Photonic Technologies Proceedings of the LANE 2016, Fürth, Germany

© 2016 The Authors. The increasing use of biomass as a fuel is leading to higher fireside corrosion of the heat exchangers in boilers due to the high chlorine and alkali metal content in the fuel. Laser cladding of Ni50Cr is a promising technique to... Read More about Laser cladding of Ni50Cr: A parametric and dilution study.

Green corrosion inhibitors: amino acids and plant extracts (2015)
Presentation / Conference Contribution
Elphick, D., Ajayi, O., Everitt, N., & Voisey, K. Green corrosion inhibitors: amino acids and plant extracts. Presented at European Federation of Corrosion Congress (Eurocorr 2015)

Corrosion inhibitors are chemicals that are used in many industries to control corro-sion. As they are injected into process streams they have to be continually replen-ished in order to maintain protection. Many chemicals used are environmentally un-...
