Corrosion inhibitor

Stray current corrosion: Stray current is the current which occurs when conductors are placed between high magnetic or electric fields. Presence of stray currents over the PCB surface can generate corrosion problems. The below figure 5 shows severe corrosion damage to micro wave module for 24 GHz. This equipment is built in controlled conditions where water condensation is possible. After few hours of use, severe corrosion was seen on the surface. Figure 5. Stray current corrosion of a micro…

Moreover, Teflon can used in chemical manufactures such as hoses that can endure very high erosive substance and sometimes, it need to move at very high of levels heat. Teflon have coating in the inner pipe and it used in erosion resistance and flexibility. Every hose will break over time, but those hose that have Teflon coating in the inside can be broken slowly than any other hoses that made of other materials because those materials do not have the same feature with Teflon. Also, Teflon…

Making The Case For Metal Roofing: The Pros Outweigh The Cons By A Long Shot What your roof is made of makes a big difference in how your home takes care of you and your family. For the following reasons, metal is, more often than not, the best choice for the job. The Pros Of Metal Roofing Longevity A metal roof is likely to remain functional and intact for as long as the home it covers does, resisting weather, rot, infestations and water all the while. According to one industry study, your…

Chemistry Task 2 Portfolio Outline and examine some uses of different metals through history, including contemporary uses, as uncombined metals or as alloys. Metal/Metal Alloy Uses Throughout History Copper - Used to make ornaments and domestic utensils in historical times (not as tools as it is a soft metal) - In modern times used in electrical wiring, pipes and plumbing fittings, jewellery, decoration, - This is due to its malleability, ductility and good electrical conductivity. Bronze…

preventing the damage done by corrosion each year in the United States. The process of corrosion costs important money and resources. Iron and steel are the most important resources that corrode. About 20% of the steel and iron produced in the United States is used to repair bridges or pipelines that have suffered from the effects of corrosion. Corrosion occurs when metals, through chemical reactions, are broken down (“Corrosion,” 2008, paras. 1-2). The process of corrosion is caused by certain…

Introduction: Energy loss is a problem that engineers face. It is caused by friction in pipes which is also called the friction head loss and that happens because of viscosity and pipe wall friction. Energy loss also happens due to local losses which occur at valves and sharp bends. Local losses are also known as minor losses because their effect is normally small in long pipelines. To understand the relationship between Reynold’s number and friction factor, the pipe friction experiment has been…

The addition of tin also improves the corrosion resistance. Iron makes the brass harder and makes the internal grain structure smaller to make proper shape of brass. Arsenic and Antimony are sometimes added to brasses that contain more than 20% zinc to inhibit corrosion. Other materials like manganese, silicon and phosphorus in a very small amount. Manufacturing Process Manufacturing process of brass…

2. Calcium “Calcium is a metal, a bright shiny metal like all other metals. Calcium is not the white powdery substance most people believe.” Calcium is found in our body very abundantly and it is very important mineral, but its absorption, assimilation and utilization is very difficult in the cell. It is present in the bones as a main component and bones are rigid and hard due to it. We can get it from milk. Bones receives calcium and fills up with it at the age of 21 years. After it, there is…

4.TAGUCHI ANALYSIS FOR THE EXPERIMENTAL RESULTS To examine the 100Cr6 bearing steel through DCT, and to identify the optimum parameter condition of the DCT process, the prediction of the Taguchi analysis is used. The Taguchi analysis and ANOVA, gives the optimized parameter setting and the most influential factor of the DCT process respectively. The quality performance of the deep cryo-treated 100Cr6 steel samples based on the L9 OA was evaluated by conducting the reciprocatory wear tests.…
