  • CMAS corrosion of EB PVD TBCs: Identifying the minimum level to initiate damage 
    Wellman, R. G.; Whitman, G.; Nicholls, John R. (2010-01-01)
    Over the last decade a significant amount of research has been conducted into the durability of thermal barrier coatings (TBCs) focusing mainly on issues of oxidation, erosion and foreign object damage (FOD). However, ...
  • Effect of microstructure and temperature on the erosion rates and mechanisms of modified EB PVD TBCs 
    Wellman, R. G.; Nicholls, John R.; Murphy, K. S. (Elsevier Science B.V., Amsterdam., 2009-10-29)
    Thermal barrier coatings (TBCs) have now been used in gas turbine engines for a number of decades and are now considered to be an accepted technology. As there is a constant drive to increase the turbine entry temperature, ...
  • Erosion of gadolinia doped EB-PVD TBCs 
    Steenbakker, R J L; Wellman, R. G.; Nicholls, John R. (Elsevier Science B.V., Amsterdam., 2006-12-01)
    Gadolinia additions have been shown to significantly reduce the thermal conductivity of EB-PVD TBCs. The aim of this paper is to further the understanding on the effects of dopants on the erosion resistance of EB-PVD ...
  • A Mechanism for the Erosion of EB PVD TBCS 
    Wellman, R. G.; Nicholls, John R. (Trans Tech Publications, Switzerland., 2000-07-10)
    Since the introduction of electron beam (EB) physical vapour deposition (PVD) TBCs and their application to moving components in the hot gas stream, erosion has become a prime concern. This project has been involved in ...
  • Methodological approach for the assessment of environmental effects of agroforestry at the landscape scale. 
    Palma, João H. N.; Graves, Anil R.; Burgess, Paul J.; Keesman, K. J.; van Keulen, Herman; Mayus, Martina; Reisner, Y.; Herzog, F. (Elsevier Science B.V., Amsterdam., 2007-04-01)
    Silvoarable agroforestry, the deliberate combined use of trees and arable crops on the same area of land, has been proposed in order to improve the environmental performance of agricultural systems in Europe. Based on ...
  • Modeling environmental benefits of silvoarable agroforestry in Europe. 
    Palma, João H. N.; Graves, Anil R.; Bunce, R. G. H.; Burgess, Paul J.; de Filippi, R.; Keesman, K. J.; van Keulen, Herman; Liagre, F.; Mayus, Martina; Moreno, G.; Reisner, Y.; Herzog, F. (Elsevier Science B.V., Amsterdam., 2007-03-01)
    Increased adoption of silvoarable agroforestry (SAF) systems in Europe, by integrating trees and arable crops on the same land, could offer a range of environmental benefits compared with conventional agricultural systems. ...
  • A Monte Carlo model for predicting the erosion rate of EB PVD TBCs 
    Wellman, R. G.; Nicholls, John R. (Elsevier Science B.V., Amsterdam., 2004-05-01)
    Since the introduction of electron beam (EB) physical vapour deposition (PVD) thermal barrier coatings (TBCs) and their application to moving components in the hot gas stream, erosion has become a prime concern. EB PVD ...
