This work deals with atmospheric corrosion to assess the degrading effects of air pollutants on ferrous and non-ferrous metals and alloys, which are mostly used as engineering materials. An exposure study was conducted in the Tuticorin port area located on the east coast of South India, in the Gulf of Mannar with Sri Lanka to the southeast. Common engineering materials, namely mild steel, galva...
In this study, solar water heater was investigated using meteorological and geographical data of 129 sites over Turkey. Three different collector types were compared in terms of absorber material (copper, galvanized sheet and selective absorber). Energy requirement for water heating, collector performances, and economical indicators were calculated with formulations using observed data. Results...
Background and purpose: Heavy metals such as chromium, nickel, and zinc are the most common contaminants found in the plating wastewater that cause environmental pollution due to non-biodegradability. This study investigated the removal of chromium, nickel, zinc and turbidity from wastewater of plating and galvanized industries by electrocoagulation technology. Material and methods: This study...
The overwhelming majority of automotive part manufacturing processes successfully process hot dip galvanized sheet metal. However, there were reported situations abrasive wear (galling), visible as narrow and long scratches, was observed on the surface formed parts. Investigations using a Slider On Sheet Tester (SOST) performed in order to determine conditions that lead scratch forming metal id...
In the first European Community Respiratory Health Survey (ECRHS I), an excess asthma risk was associated with high exposure to gases and fumes, mineral and biological dusts. In a 9-year follow-up study (ECRHS II), the aim was to study if welding at work increases the risk of asthma symptoms, wheeze and chronic bronchitis symptoms. The study also aimed to identify specific welding risk factors....
This study evaluates the macrostructure, microstructure, hardness, and tensile strength in dissimilar metal welding applied to bus body construction. The process involved joining hollow stainless steel galvanized at dimensions of 80 x 40 3.2 mm through Gas Metal Arc Welding (GMAW). current was varied 90, 100, 110 A while ER70S-6 electrodes with diameters 0.8 1.0 were used. results showed that e...
Metals such as cobalt (Co), copper (Cu), iron (Fe) and nickel (Ni) are essential for nor‐ mal plant growth and development since they contribute to the function of many en‐ zymes and proteins. However, metals can potentially become toxic to plants when they are present at high levels in their bioavailable forms (Hall, 2002). Phytotoxic levels of one or more inorganic ions in soil can be found i...
