Use of a Laser/tiG Combination for Surface Modification of ti-6Al-4V Alloy

引用

Journal of Materials Science & Technology 2001年第2期17卷 237-239页

作者： M.Labudovic and R.Kovacevic Southern Methodist University, Dept. of Mechanical Engineering, dallas, Texas, U.S.A. So Methodist Univ Dept Mech Engn Dallas TX 75275 USA

The surface modification of materials such as ti-6Al-4V is necessary to improve their wear resistant properties for use in tribological applications. In this paper it is shown that a laser with low power and tungsten inert gas (tiG) can be combined together for surface modification of ti-6Al-4V alloy, and when performed in a controlled atmosphere of pure nitrogen or a mixture of nitrogen and argon, can produce a wear-resistant surface alloy. Compared with laser processing, a cheaper surface modification process has been developed involving a shorter processing time, which is free of stringent requirements such as a vacuum system.

This paper introduces the first tunable ferroelectric capacitor(FeCAP)-based unreleased RF MEMS resonator,integrated seamlessly in Texas Instruments’130 nm Ferroelectric RAM(FeRAM)*** designs presented here are monolithically integrated in solid-state CMOS technology,with no post-processing or release step typical of other MEMS *** array of FeCAPs in this complementary metal-oxide-semiconductor(CMOS)technology’s back-end-of-line(BEOL)process were used to define the acoustic resonance cavity as well as the electromechanical *** achieve high quality factor(Q)of the resonator,acoustic waveguiding for vertical confinement within the CMOS stack is studied and *** design considerations are discussed to obtain lateral confinement and suppression of spurious *** FeCAP resonator is demonstrated with fundamental resonance at 703 MHz and Q of *** gives a frequency-quality factor product f·Q=7:11×10^(11) which is 1.6×higher than the most state-of-the-art Pb(Zr,ti)O_(3)(PZT)*** to the ferroelectric characteristics of the FeCAPs,transduction of the resonator can be switched on and off by adjusting the electric *** this case,the resonance can be turned off completely at±0.3 V corresponding to the coercive voltage of the constituent FeCAP *** novel switchable resonators may have promising applications in on-chip timing,ad-hoc radio front ends,and chip-scale sensors.
