Nanostructured zirconia layers as thermal barrier coatings
Journal Title: INCAS BULLETIN - Year 2011, Vol 3, Issue 3
Abstract
The coatings obtained by thermal spray are used both as antioxidant and connection materials (e.g. MCrAlY type alloys) as well as thermal barrier coatings (e.g. partially stabilized zirconia oxide with yttria oxide). This paper studies the characteristics of the coatings obtained with nanostructured powders by thermal spraying and air plasma jet metallization. Testing of coatings is done against the most disturbing factor, thermal shock. Structural changes occurring after thermal shock tests are highlighted by investigations of optical and electronic microscopy. The results obtained after quick thermal shock show a good morphological and surface behavior of the developed coatings.
