MODELLING AND CHARACTERIZATION OF THE MANUFACTURING PROCESS OF CERAMIC THERMAL BARRIER COATINGS (TBCS)

Objective


The project proposes a detailed investigation of certain industrial systems for the production of plasma spraying coatings to improve the understanding of the process of coating formation and so build more reliable correlations between the process parameters that can be directly controlled and the quality of coatings produced.

To this end a combined experimental and theoretical programme is set out. A limited set of coatings will be manufactured under control specifications and they will be analysed and characterised in various laboratories using several techniques. Physical models and simulation techniques will be developed to model the process as a whole and to correlate the process parameters with the coating characteristics.

The programme will make comparisons between experimental results and theoretical modelling at all stages of the work. We will use the knowledge gained from the correlations between the process parameters and the quality of coatings to build an expert system to be used both as an intelligent database containing knowledge gained in the present project and as a prototype tool for coating fabrication.
