摘要：
In this article, a new synthesis process to fabricate PbTiO3/NiTi composite film is reported. A transitional PbTiO3 film, prepared on NiTi substrate by a hydrothermal reaction, was introduced to improve the adhesion strength of the composite. Then an outer PbTiO3 film was fabricated on the transitional layer by a sol-gel method. No cracks or obvious defects were observed on the outer ceramic film. Scratch tests showed that the adhesion strength of composite film was improved greatly by using this new synthesis process. (C) 2000 Elsevier Science Ltd. Ail rights reserved.
