Abstract

Keywords: Ni-W alloy; empirical electron theory; valence electron structure; bond length difference Abstract. To study deposited Ni-W alloy on electronic level, empirical electron theory of solids and molecules (EET) was used to calculate valence electron structures (VES). In addition, high-resolution transmission electron microscope (TEM) was used to identify crystal features. Regular arrangement exists according to concentric rings diffraction pattern. That provides an experimental basis for crystal VES. And VES of Ni-W alloy was contrasted to pure Ni metal. It is indicate that melting point, strength, corrosion resistance, and wear resistance of Ni-W alloy are significantly higher than those of pure Ni metal
