ORTHOPHOSPHATE THERMAL BARRIER COATING MATERIAL WITH HIGH COEFFICIENT OF THERMAL EXPANSION AND PREPARATION METHOD THEREOF
To provide an orthophosphate thermal barrier coating material with a high coefficient of thermal expansion and a preparation method thereof.SOLUTION: This invention relates to an orthophosphate thermal barrier coating material with a high coefficient of thermal expansion and a preparation method thereof. By this invention, ReM3P3O12 series ceramics having an eulytite crystal structure are prepared by a high-temperature solid-phase reaction for the first time. ReM3P3O12 ceramics belong to a -43 m space group of a cubic crystal system, which not only has a higher melting point and an excellent high-temperature phase stability, but also has a lower thermal conductivity and a suitable coefficient of thermal expansion. It can effectively alleviate the stress caused by the mismatch of the coefficient of thermal expansion of the base material and the ceramic layer, so as to meet the requirements of thermal insulation and high-temperature oxidation and corrosion resistance of the hot end parts in long-term service, which has application prospects in the field of thermal barrier coatings.SELECTED DRAWING: Figure 1
【課題】高熱膨張係数オルトリン酸塩遮熱コーティング材料及びその製造方法を提供する。【解決手段】本発明は、高熱膨張係数オルトリン酸塩遮熱コーティング材料及びその製造方法に関し、本発明は、高温固相反応法を使用して、珪蒼鉛石構造を有するＲｅＭ３Ｐ３Ｏ１２シリーズセラミックを初めて調製する。該ＲｅＭ３Ｐ３Ｏ１２セラミックは、立方晶系－４３ｍ点群に属する。融点が高く、高温相安定性に優れているだけでなく、熱伝導率が低く、適切な熱膨張係数を備えているため、基材とセラミック層の熱膨張係数の不一致による応力を効果的に緩和することができ、長期使用の場合のホットエンド部品の断熱と高温酸化腐食耐性のニーズを満たし、遮熱コーティングの分野での応用の見通しがある。【選択図】図１
