High temperature oxidation resistance of thermally sprayed ceramic oxide on austenitic stainless as thermal barrier coatings


Stainless steel is an attractive material and has established uses in industry for a variety of applications, usually due to its corrosion resistance and strength. Even so, research is still being conducted on steels to further enhance their properties and optimize their performance. However, given the diversity of applications for which stainless steel is suitable, it is not surprising that producers are continually developing new grades to meet the needs of particularly demanding applications.

  • Austenitic stainless steel is a choice that is extensively used in the power plant generation, gas turbine and aerospace industries for high temperature applications
  • The application of Austenitic stainless steel as the material for components operating in a severe high temperature environments has been a concern
  • There is a need for power efficiency and durability in aircraft propulsion and electricity generation and a need for higher hot section temperature resistance.

Research proposal

Folorunso Omoniyi developed a research paper to study the high temperature oxidation and corrosion resistance of thermally sprayed ceramic oxide powders on austenitic stainless steel 316L as thermal barrier coatings as the means of improving engineering properties and advancement in the nanotechnology materials industry.

His research aims to:

  • Assess the high temperature oxidation and corrosion resistance of ceramic oxide impregnated on austenitic stainless steel 316L
  • Investigate the possible chemical interactions between the coating materials and austenitic stainless steel 316L
  • Determine the phase transformations and their impact on the overall thermal barrier coatings
  • Establish a compositional improved structured alloy.

Austenitic Stainless Steel

The material of focus throughout this project is austenitic stainless steel AISI 316L.
Austenitic stainless steels are widelyused and well-known for their exceptionally high toughness, good ductility, formability and excellent corrosion resistance.

Austenitic stainless steels generally have better corrosion resistance than ferritic and martensitic steels. AISI 316L, is very widely used for its corrosion resistance, and generally has better mechanical properties, and corrosion resistance in certain environments.
