Formation of SiOx nano-films at laser ablation of Si and composite SiC-ceramic

By methods of electron microscopy, atomic force microscopy, X-ray microanalysis the influence of continuous IR laser irradiation ( ∏ = 1064 nm, P = 240 mW, 175 W and 210 W) on Si, SiC, and SiC-Cr 5 Si 3 ceramics is investigated. It is established that the basic product of ablation is silicon. Depend...

Descripción
Sumario:By methods of electron microscopy, atomic force microscopy, X-ray microanalysis the influence of continuous IR laser irradiation ( ∏ = 1064 nm, P = 240 mW, 175 W and 210 W) on Si, SiC, and SiC-Cr 5 Si 3 ceramics is investigated. It is established that the basic product of ablation is silicon. Depending on capacity of radiation, time of irradiation and composition of the gas environment on a surface of collection plate films of SiO x and SiO x :N, where x ∑ 2, are precipitated. At various stages of an irradiation (from a mode of evaporation up to plasma formation) a nano-films of various morphology are formed.
