Role of numerical modelling and optimization in the manufacturing of boiler steel surfaces with coatings.

The role of computing and optimization is essential for the processing of any material. The need of numerical modelling has been presented to understand the behaviour of coatings at high temperature. The selection of a particular material and optimization of process is responsible for an effective and significant and performance of any material. To select an efficient material for high temperature application, the optimization and empirical approaches have been taken in account in the present study. On the basis a deep literature survey the material for high temperature application is opted. To examine the microstructural characteristics of the ceramic coatings, the optimized coatings were studied in depth. Three coatings were considered in the present work for the analysis of surface features. The concept of heat flow was considered to know the formed topographical features. The application of TiO₂ in Al₂O₃ has resulted in the decrease in the melting point of coating and thereby reduction in the porosity was observed. [ABSTRACT FROM AUTHOR]
