Abstract
A protective glass- based coating of N-15 and N-25 glass was deposited on the Crofer steel by slurry method and its effect on 7500C-8500C has been studied. Oxidation behavior of steel at high temperature of 12500C was also investigated. Interface study of N-25 glass &Crofer steel and N-15 glass &Crofer steel has been done and found that coating of N-15 glass on the steel is more smooth and effective to prevent the surface of steel from corrosion.Structural study of different type of glass has also been done. Bare steel sample as well as coated steel sample was taken for the study of their isothermal oxidation which shows that the glass coating could prevent the corrosion and improve the quality of steel surface for practical application.This corrosion resistant effect takes place because a thin layer of molten glass is formed on the surface of steel at high temperature. This layer then acts as a diffusion barrier. This coating of glass and steel is cost effective, hence have wide application in many infrastructural construction where corrosion is a big challenge. It is also very useful in marine conditions where steel is most likely to be corroded be sea water.
Highlights
Glass is generally defined as the solid which possess a non-crystalline or amorphous crystal structure and when its temperature rises towards its melting point, it shows the transformation region of glass
Analysis revealed that diffusion of Cr from steel into glass leads to formation of flowery pattern which might have occurred due to presence of defect structure as this pattern is not observed in other areas.Observations shows that Si, Ca, Al, Ti, Na, O, Cr and Fe elements are uniformly distributed in the selected area
To keep the growth rate of Cr2O3 slower proper supply of Cr from steel is required which can be achieved at this temperature by reducing the diffusion of oxygen from air which is possible because of presence of glass coating [20]
Summary
Glass is generally defined as the solid which possess a non-crystalline or amorphous crystal structure and when its temperature rises towards its melting point, it shows the transformation region of glass. These are formed by solidification of the melt and shows the atomic structure similar to the liquid phase which is supercooled and displays various mechanical properties of a solid. 4) The minimum number of shared corners of every polyhedron must be three This model can be considered as the best possible presentation of various silicate glasses and can be generated as a model based on random-array concept where units of structure are arranged randomly.
