电子束蒸发制备碳化硼微球涂层的工艺研究
Process of boron carbide micro-shell coatings deposited by electron beam evaporation
摘要
Abstract
A 3D system of deposition was designed and used to deposit boron carbide micro-shell coatings with electron beam evaporation. The coatings were deposited with the mandrel of marbles whose diameters are lmm. The effect of the vibration frequency of screen and preparation process of electron beam on the deposition rate, and the thickness and roughness of coatings were investigated. The thickness and components of coatings were measured by X-ray radiography and X-ray photoelectron spectroscopy (XPS), respectively. The surface roughness of coating was characterized by atomic force microscope (AFM). The results reveal that the main ingredients of the coatings are B4C and the surfaces of the coatings are quite smooth and homogeneous. The surface topography of the coatings are optimum at the vibration frequency of screen is 0.25Hz, vacuum under 3 × 10-3 Pa, high pressure being 6 kV and beam current from 100 mA to 120 mA.关键词
