Effects of Micro - Arc Oxidation on Dimensional Accuracy and Properties of 6061 Aluminum Alloy Bush
Published 2021-06-01“…At present, there are few studies on the film structure of micro-arc oxidation film on aluminum alloy and the dimensional accuracy change of precision thin wall parts before and after micro-arc oxidation.The samples of 6061 aluminum alloy bushing(precision thin wall parts), used for the aircraft engine fuel control system accessory,were treated by four different micro-arc oxidation processes(A, B, C and D).The microstructure,composition and micro-hardness of micro-arc oxidation ceramic layer were detected and analyzed.Besides, the inner diameter,the cylindricity and the surface roughness of the inner hole before and after MAO were tested.Results showed that the micro-arc oxidation ceramic layer obtained by C and D processing parameters with special auxiliary equipment had excellent properties.The surface hardness could reach 900 HV,which was 6 times of that of 6061 aluminum alloy matrix material.The micro-arc oxidation ceramic layer significantly improved the wear resistance and service life of parts, at the same time met the strict requirement of dimensional precision.This study laid a foundation for the engineering application of aluminum alloy micro-arc oxidation process.…”

Utilization of NDVI, VTCI and WDI indices in analyzing the effects of drought severity and duration on vegetation density in Siminehrood catchment
Published 2020-12-01“…Visible, near-infrared and thermal bands are among the most widely used in the production of products such as vegetation and surface temperature. In this study, from MODIS sensor data to investigate and find the coefficients of spatial relationship between vegetation-surface temperature index (NDVI-TS) and NDVI-ΔTS to extract the time of agricultural drought from June to October 2007 to 2010 in the catchment Siminehrood has been extracted from the Temperature-Vegetation Condition Index (VTCI) and the Water Lack Index (WDI), which are able to detect drought stress on a regional scale. …”
