氮硅涂层陶瓷刀具切削铸铁磨损机理研究
Published 2021-01-01“…In order to study the cutting performance and wear mechanism of nitrogen-silicon coated ceramic tools,TiAlN and CrAlN coatings were deposited on the surface of silicon nitride tool by physical vapor deposition( PVD).The tool life and wear mechanism were systematically studied by cutting gray cast iron HT200.Different depths of cut,feed rate and cutting speed were discussed.The wear condition of the lower tool,and pays attention to the optimal cutting speed of ceramic coated cast iron.The cutting performance of the tool under different cutting speeds is analyzed.The results show that the TiAlN and CrAlN coated tools can effectively improve the hardness of the tool.There is no obvious difference in the wear mechanism of gray cast iron.The wear mechanism is mainly abrasive wear.With the increase of cutting speed( V<sub>c</sub>= 250 m/min ~ 450 m/min),the cutting life of silicon nitride coated ceramic tools is rapidly reduced.Provide theoretical guidance for the development of nitrogen-silicon coated ceramic tools.…”

Study for Urban Dike-pond System on Non-point Pollution Control in Hydro-fluctuation Belt of the Hanfeng Lake
Published 2020-01-01“…Based on the wetland system of urban landscape dike-pond,and enhanced biological treatment of dike-pond by planting a variety of aquatic plants,this paper discusses the ability of multi-pond wetland system to reduce nitrogen,phosphorus,COD and other pollutants in urban surface runoff,and analyzes the concentration change of nitrogen,phosphorus,COD and other pollutants in urban surface along the lake.The results show that:Before and after rain,the multi-pond system has a better treatment effect on urban surface runoff;the larger the area and the higher the vegetation coverage,the better the treatment effect on surface runoff sewage.Both before and after the rain,artificially designed dike-ponds have higher pollutant removal efficiency than the natural dike-ponds.In overall,the wetland systems of urban landscape dike-pond have better treatment effect on surface runoff,the removal efficiency after rain is higher than that before rain,and TN,TP,NH<sup>+</sup><sub>4</sub>-N,COD reduces along the lake.…”
