Metal Based Intelligent Composite with SMA Materials. International Conference on

摘要

Fabrication of a metal-based intelligent composite with shape memory alloy (SMA)wires was investigated. Composition gradient films of Al2O3 or Ta(x)O(y)Nz can be coated on the NiTi wire by the ion-implantation, ion-sputtering deposition, and high-temperature oxidation technique. Test results indicate that such films could have very good adhesion with the NiTi wire and allow the SMA wires and metal matrix to have good insulation properties. The vibration test further demonstrates that the aluminum-based composite-embedded with the NiTi SMA wire could significantly reduce vibration. (MM).
