By using liquid - liquid extraction and photochemical desulfurization process , the technology for photochemical degradation of sulfur compounds and kinetics of reaction was investigated
2.
Microstructure of the composite layer was analyzed with help of optical microscope , scanning electronic microscope ( sem ) , electronic probe microanalysis ( epma ) and x - ray diffraction ( xrd ) . the compacting of the billet and the forming mechanism of the carbide reinforcement were studied based on thermodynamics and kinetics of reaction , sintering theory and the result of dta . at the same time , the wear - resistance of the composite layer was studied under condition of dry sliding friction
