| titleOfInvention | Plasma-etching-resistant granulated yttrium oxide for hot spraying and preparation method thereof |
| abstract | The invention belongs to the technical field of hot spraying, and particularly relates to plasma-etching-resistant granulated yttrium oxide for hot spraying and a preparation method thereof. The preparation method of the plasma-etching-resistant granulated yttrium oxide for hot spraying comprises the following steps: preparing nano or ultrafine yttrium oxide powder and deionized water or an organic solution into a paste, performing depolymerization and reduction, adding surface activity activator into the paste for preparation, and performing hot expansion balling and high-temperature densification treatment to obtain the granulated yttrium oxide for hot spraying. According to the invention, the surface activity activator is added into the paste before hot expansion balling, so that the prepared granulated yttrium oxide for hot spraying is favorable in spherical degree, and the high-spherical-degree favorable-flowability high-density granulated yttrium oxide for hot spraying can be obtained without later spheroidization, thereby achieving favorable flowability during hot spraying, ensuring that the supply of the granulated yttrium oxide for hot spraying is more stable, and providing a guarantee for obtaining a hot spray coating having a uniform thickness. |
