Currently many aerospace vehicle systems require lightweight, high performance pressurized tank for storage of propellant, nitrogen, oxygen, or other medium. Aircrafts have several needs for high-pressure stored gas, like aircraft escape slide inflation systems, emergency oxygen supply, landing gear actuator, engine pressurized air start system and on-board inert gas generating system nitrogen ...
Due to special properties such as low density, high strength and high corrosion resistance Ti-6Al-4V alloy has been used extensively in various industries, especially in the aerospace aspects. However the major problem of this alloy is its poor tribological properties under relatively high loads. In the present study, in order to improve the tribological properties of mentioned alloy, chromium ...
Pathogenic microorganisms are able to adhere on equipment surfaces, being possible to contaminate food during processing. Salmonella spp. and Listeria monocytogenes are important pathogens that can be transmitted by food, causing severe foodborne diseases. Most surfaces of food processing industry are made of stainless steel joined by welds. However currently, there are few studies evaluating t...
