Project presentation.

TheBarCode addresses the following scientific and technological issues, which shall offer significant impact concerning successful implementation of energy efficient high temperature generation units.

  • New TBC formulations with long-term stability, more resistant under extremely severe operating conditions (e.g. creep, fatigue, thermal-mechanical fatigue, oxidation and their interactions) thus the maximum application temperature will be longer, leading to higher performance during energy generation.
  • Flexible and cost effective production systems based on thermal spray in order to realize patterned functional TBCs with improved properties.
  • Application of structural analysis, fracture mechanics and Computational Fluid Dynamics (CFD) including heat transfer, fluid-structure interactions and conjugate heat transfer models for the development of detailed models for the operational performance and prediction of spallation and failure.
  • Environmentally friendly process using chemical formulations free of hazardous and toxic solvents.
  • Standardised thermo-mechanical, tribological and coating adhesion testing including thermal shock testing in extreme conditions (at a rate up to 70°C/second).

    Accordingly the logical path of the implementation of the project can be outlined in four interrelated phases:

    A. Materials synthesis and testing: i) development of top coat materials and wet or dry formulations suitable for topcoats deposition, ii) development of bond coat materials (including functional diffusion barriers).

    B. Coatings development, fabrication and testing: i) Application and optimization of dry deposition methodology for the new materials, ii) Application and optimization of wet deposition methodology for the new formulations, iii) Development of smart coatings of tunable nano and microstructure (graded)

    A. Development of models and prediction tools: i) Numerical modelling of the TBCs performance focused on experimental and theoretical parameters, ii) Computational Fluid Dynamics based optimization and energy efficiency assessment, iii) Service lifetime prediction tools (based on CFD and fracture and wear modelling).

    B. Assessment of Technology: Assessment of product (materials and coatings), process (deposition technology) efficiency, sustainability and cost & performance effectiveness upon application, for the entire life-time of the project; feedback (where necessary) to facilitate the decision making process.

    The total duration of the project is 36 months. During the first stage of the project (month 1- 18), new materials and their coatings will be used to develop the optimized coatings and protocols and start up models. These materials and methods will meet the requirements and industrial interest of the end user partner of THEBARCODE. The second stage (month 15 – 36) will focus on the tuning, implementation and transfer of the methodologies (TBCs, models) to the application (real parts & units, energy efficiency).

    The project is implemented from 1/1/2013 until the 31/12/2015
