| 摘要 |
A lightweight, high strength and corrosion resistant composite metallic m aterial is disclosed herein. The composite metallic material typically compr ises a high-to-weight ratio, low density core material; and a corrosion resi stant protective refractory metal layer. The method for making the composite metallic material comprises the steps of surface activating the core materi al and forming a refractory metal on the surface of the surface activated co re material by physical, chemical or electrochemical processes. Such a compo site material is suitable for making biomaterials, corrosion resistant equip ment and industrial electrodes. |
