Abstract

We studied the expanding and reducing of cracks in thermal cycling such as heating and cooling for the ZrO₂+8%Y₂O₃ layer built up from plasma spray on stainless steel and carbon steel, with the following Results<br>1) The ZrO₂+8%Y₂O₃ layer showed self-repair in thermal cycling such as heating and cooling.<br>2) The ZrO₂+8%Y₂O₃ layer sprayed on carbon steel had better self-repair than that sprayed on stainless steel, indicating that ZrO₂+8%Y₂O₃ layer self-repair was influenced by a substrate's expansion coefficient.<br>3) Self-repair of the ZrO₂+8%Y₂O₃ layer is the characteristic property of ZrO₂+8%Y₂O₃ layer built up by spraying particles.
