查询词典 zinc-plate process

The carbonaceous lead zinc ore in Inner Mongolia is very large in reserve,but it contains a high level carbon,which interferes with the selective flotation of these ores,making the selective process target very low and economic benefit poor.In recent years,the decarbonizing technology has been greatly improved that provides enough reliable information to exploit these ores

In this thesis, the phase diagram of Zn-Al binary system on 10~69.5 w% was reinvestigated by using differential scanning calorimeter, X-ray diffraction and pushrod dilatometer. The process of isothermal transformation during the aging of high-Aluminum-Zinc-based alloy was studied by using differential scanning calorimetry, and the aging behavior of the alloy was analyzed at the aspect of thermal analysis kinetics. The change of microstructure which the alloy was being heated was observed on high-temperature metallurgical microscope. The microstructure and wear-friction properties were compared among the alloys treated with several different heat treatment processes, and a model for heat treatment processes was proposed based on artificial neural network,so as to predict the relationship between friction coefficient and parameters of aging treatment such as aging temperature and time.
