Corrosion

In the 70’s a few companies tried their hand at making outdoor coils using all aluminum, environmental corrosion turned out to be a conquering opponent. Only one company had success, which was Trane Company, due to a very cleaver design, where the condensing tube is covered with glue an additional piece of aluminum. This additional piece is sacrificed to the environment, allowing the primary tube to stay in tack. Trane patented the process in details making it extremely hard to duplicate. In a…

quality knife at a lesser price! 3.Stainless steel won’t rust or stain Stainless steel is more impervious to corrosion than a other steel qualities, yet they are not 100 percent stain or rust-free. However, given enough mistreatment, even the best stainless steel blade will rust and stain! Stainless steel still should be maintained routinely with sharpening and oiling, to prevent corrosion, especially of they are being exposed to water for longer duration while in use. Keeping your knife…

Gold is widely used in modern day medicine to treat disorders. This is because gold is very resistant to bacteria. Bacteria are microscopic single-celled organisms. Bacteria are prokaryotes, meaning the entire organism consists of a single cell with a simple internal structure. The DNA of a prokaryote is neatly packed in the nucleus. The bacterial DNA floats freely in a twisted thread-like mass called the nucleoid. Gold is unaffected by almost everything. The only materials that can affect gold…

Animal testing is known as “The use of non-human animals in research and development projects, especially for purpose of determining the safety of substances such as foods and drugs (Dictonary.com)” It is said that there are millions of vertebrae animals used in the testing such as mice, rats, birds, monkeys, dogs, cats and farm animals. Majority of the animals used in testing are either put to sleep or killed to experiment on. Last year I had some experience of my own to see this for my own…

2.1 Silicon-Carbide (SiC) Initially, Silicon carbide (SiC) was accidentally introduced by Edward G. Acheson in 1890. Silicon Carbide can be stated as a chemical compound of Silicon and the carbon. Edward G. Acheson was running an experiment on the synthesis of diamonds. At that time, it was produced by a high temperature electro chemical reaction of sand and carbon. We can also find the silicon carbide very rarely in nature in very small amounts. Also Edward G. Acheson was the first person to…

biofilm is defined as “an assemblage of microbial cells that is irreversibly associated (not removed by gentle rinsing) with a surface and enclosed in a matrix of primarily polysaccharide material. Noncellular materials such as mineral crystals, corrosion particles, clay or silt particles, or blood components, depending on the environment in which the biofilm has developed, may also be found in the biofilm matrix (Donlan).” Biofilm associated microorganisms are different from planktonic, or…

Locking mechanism The joints had to be such that they can be loosened and tightened at any required configuration, this obstacle was overcome by the use of wing nut at the end of the screw instead of a normal nut, and the image below shows the wing nut and bolt. This is the most cost effective yet strong way of locking the joints compared to knobs and other clamp mechanisms. Materials For the Robot Arm Construction our group members had a variety of materials to choose from, these materials…

COMPARATIVE STUDY ON FRICTION WELDED AND ELECTRON BEAM WELDED JOINTS MADE BY 20VNiMoCr120 STEEL Gabriela IANCULESCU*, Lucia Violeta MELNIC, Marian Andrei GURĂU Ovidius University of Constanta Abstract: In the paper there are presented experimental results concerning mechanical characteristics of friction-welded joints in comparison with electron beam welded joints, made by 20VNiMoCr120 heat-resistant steel, which are part of some elements working at high pressure and temperature. The paper…

also damage aquatic plants, leads to animal’s death and human health issues. Changes in the salinity of a lake can also affect the way the water change. Another problem for using road salt deicing system, its ruins our infrastructure. It leads to corrosion of metal and steel, damage all underground pipes and wire connections, ruin the structure of concrete and crack concrete or road asphalt. Finally, it’s not environment friendly, its expensive process, and not safe for everyone. Road salt…
