Time of wetness, 2 SO and − Cl pollutants are three key factors for the selection of metal materials in engineering applications and the determination of atmospheric corrosivity categories. In the past, when one or more corrosive factors data is missing, corrosive factors categories were often subjectively determined according to expert experience. In order to overcome such difficulty, this pap...

The paper deals with monitoring and analyzing the indoor environmental parameters through remote data collection to evaluate pollution moisture infiltration effects on aircraft heritage conservation. First, based meteorological data, penetration airborne into spaces of a site (hangar) stored historic aircrafts are determined. hangar under investigation is located in Aviation museum Kbely, Pragu...

Abstract Groundwater is a vital natural resource in the Kathua region of Union Territory Jammu and Kashmir, Northern India, where it used for domestic, irrigation, industrial purposes. The main purpose this study was to assess hydrochemistry groundwater determine its suitability drinking, uses region. In study, 75 samples were collected analyzed physicochemical parameters such as electrical con...

This investigation assesses the effect of alloy composition and temperature in corrosivity ternary carbonate eutectic, 32% Li2CO3, 33% Na2CO3, 35% K2CO3. To this end, an iron-based alloy, coded as 51Fe-24Cr-20Ni, a nickel-based 5Fe–23Cr-58Ni-8Mo, were exposed to mixture for 500 h at 700 ºC, 750 ºC 800 under static atmospheric air. The results revealed that corrosion extension does not have line...

Transmission towers and substations are used in a variety of natural environments, coupled with the interference surrounding production life, facing test soil corrosion. Based on experimental data 72 samples from five cities Southern Hebei Province, resistivity, pH value moisture content were investigated, corrosion grade distribution map obtained. It provides reference for collection corrosivi...
