Study on the Microstructure and Properties of Suspensory Wire in DVD CD-ROM Head

Abstract:

Article Preview

The suspensory wire is widely applied in the fields of DVD CD-ROM head and various sensors. In this paper, the suspensory wires are analyzed with the SEM, X-ray energy spectrum and Hydrogen power spectrum et al. The research results show that the alloy composition of the suspensory wire is the composite materials, which is composed of silver, beryllium and copper bimetal; The Nano-indentation hardness tester is also did using the hanging Nano-indentation experiments on the suspensory wire, it’s to obtain more accurate mechanical properties parameters of material hardness and so on, then we get the average hardness of suspensory wire is 3.891 GPa; The average elasticity modulus decreases as the aging treatment time increases, and the average tensile strength increases as the aging treatment time increases.
