Galvanic Corrosion Fun Facts: 1. Electrochemical Reaction: Galvanic corrosion occurs when two different metals are in electrical contact in the presence of an electrolyte, like seawater. The less noble metal becomes the anode and corrodes faster. 2.Battery Effect: This type of corrosion is similar to how a battery works. The two metals and the electrolyte create an electrochemical cell, causing the flow of electrical current and resulting in the corrosion of the anode metal. 3.Common Pairs: Common metal pairs that can cause galvanic corrosion include aluminum and steel, copper and aluminum, and zinc and copper. 4.Sacrificial Anodes: A common method to combat galvanic corrosion is the use of sacrificial anodes, often made from zinc or magnesium, which corrode instead of the protected metal. This technique is widely used in marine environments. 5.Nobel Prizes: The principles behind galvanic corrosion are based on electrochemistry, a field that has led to multiple Nobel Prizes, including those for understanding the electrochemical processes and for the development of the lithium-ion battery. 🔔 How about use GalBar - the exclusive product from curecorr.com to protect the dissimilar metals and stop corrosion before it has a chance to start!!!!

Australia and the West Need #CriticalMinerals Now More Than Ever.   The Australian Financial Review China's latest export controls on antimony shine a spotlight on the urgent need for secure, diversified critical mineral supply chains. As a nation, we must reduce our reliance on foreign sources for essential materials like #lithium, #gallium, #rareearths, and #copper.   Link: https://lnkd.in/gqCciJ2J.   Gallium, a critical metal essential for #semiconductors, #defense, and #renewableenergy, is currently 98% sourced from China. With the USA, UK, EU, and Australia recognising its strategic importance, the push for a more balanced supply chain is accelerating.   Terrain Minerals LTD (ASX: #TMX) is at the forefront of exploring for Australia’s critical mineral supply chain. Our Western Australian projects are strategically positioned to deliver the resources essential for both #nationalsecurity and a #sustainable future.   Our high-grade Gallium Clay project in WA has the potential to supply the exponential growth of technologies like generative #AI, which rely on advanced #semiconductors. Gallium's ability to enhance chip performance and efficiency makes it a cornerstone of the digital age.

China and other foreign exporters are tightening their controls on #graphite, a critical component in #EV batteries. China is a major world supplier of graphite and these tightened restrictions pose a major challenge for EV and battery manufacturers in the U.S. Earlier this year, our CTO, Gregory Hitz, sat down with Ray Chalmers at Battery Technology and explained that this exact scenario is why ION Storage Systems batteries are the future of #solidstate. Instead of graphite, our batteries use a unique ceramic structure inside the cell that requires no anode material. Our batteries enable safer, high-energy density cells without using limited resources like graphite.

China, Russia, and Iran grow closer, refine production capacity, and grow bolder as their strategies support and align with each other. Oh by the way, the DPRK had a pretty good year as well. Mr. Jones, the author of Three Dangerous Men (I recommend) makes a great case as to why this is about more than a regional conflict. It is about credibility, deterrence, reduction of opportune malign behavior. We must stand strong. https://lnkd.in/eBu-eUqC

Eastful Group Aerospace Cables： This Aerospace Cables meets basic requirements for being lightweight, small in diameter, and resistant to high temperatures, wear, fuel oil, lubricants, and other chemicals, as outlined in the national military standard GJB 773A-2000. It utilizes various conductor materials including tin-plated copper (alloy), silver-plated copper (alloy), and nickel-plated copper (alloy) wires with restricted use temperatures, insulating materials such as PTFE and ETFE copolymer, shielding materials like tin-plated round (flat) wire, silver-plated round (flat) copper wire, and nickel-plated round (household) silver wire, and sheath materials including extruded FEP, PVDF, or ETFE sheaths. #AerospaceCables #AerospaceWire #AerospaceWireandCable

In a recent report by Gunvor, and as reported by Bloomberg, it was revealed that approximately 600 thousand barrels of daily oil refining capacity in Russia were knocked offline as a result of strikes by Ukrainian drones on Russian refineries. #EUToday #russiaukrainewar #standwithukraine

Ukraine paralyzed the work of a Russian metallurgical plant that is critical for its defense industry. On the night of July 1, the Main Directorate of Intelligence and the Foreign Intelligence Service, paralyzed operations at the Oskol Electrometallurgical Plant (OEMK). This plant is the only full-cycle metallurgical enterprise in Russia. As a result of the attack by Ukrainian kamikaze drones, two main electrical substations in the Belgorod region stopped working. Therefore, the company was de-energized, all-electric arc furnaces were stopped, and their metal solidified. The Russians must clean the furnaces and replace the arc elements to restart them, but this can take months. There is also a possibility that new furnaces will have to be installed. The metallurgical plant is important for the Russian military-industrial complex, as it produces high-quality steel for the automotive industry and engineered applications. Also on July 1, Ukrainian pilots inflicted a devastating blow on an ammunition depot in the temporarily occupied Crimea. https://lnkd.in/d_CvEfMk

On May 30, 2024, the Department of Defense issued a final rule implementing Section 844 of the Fiscal Year 2021 National Defense Authorization Act and Section 854 of the FY 2024 NDAA by amending DFARS 225.7018-2 and accompanying DFARS clause 252.225-7052, which restrict DoD from acquiring certain metals and magnets from “covered countries” of Iran, North Korea, Russia, and China, to prohibit even earlier inputs in the supply chain from occurring in these countries.

The “seventh function of #Marine aviation” has always been and will continue to be essential to the effectiveness of #USMC #aviation. Just as important are the right VTOL and STOVL #aircraft to take full advantage of them.

The M4 Carbine is a 5.56x45mm NATO caliber, gas-operated, selective-fire weapon used extensively by the U.S. Armed Forces. It weighs approximately 6.36 lbs (2.88 kg) unloaded, with a length of 33 inches (83.82 cm) with the stock extended and 29.75 inches (75.57 cm) with the stock retracted. Its 14.5-inch (37 cm) barrel allows a cyclic rate of fire between 700-950 rounds per minute, with a muzzle velocity of about 2,970 feet per second (905 m/s). The effective range is around 500 meters (550 yards) for point targets and 600 meters (660 yards) for area targets. The M4 is highly regarded for its accuracy in both short and medium ranges, essential for urban and close-quarters combat. Its reliability in various conditions is notable, though it demands regular maintenance, especially in dusty environments. A significant advantage of the M4 is its modularity, allowing customization with different optics, sights, and accessories, making it adaptable to various mission requirements. Handling is another strong suit, with its lightweight and adjustable stock facilitating ease of maneuverability. The mild recoil further aids in control during rapid fire, enhancing the user's ability to make quick follow-up shots. Despite its advantages, the M4 faces criticism for its shorter barrel, which some argue reduces effective range and muzzle velocity compared to longer rifles like the M16. The need for regular maintenance in harsh environments and concerns about the stopping power of the 5.56mm round, especially at longer ranges, are also noted drawbacks. Enhancements over the years, including the development of the M4A1 with a heavier barrel and full-auto capability, have addressed some of these issues, improving durability and firepower. Overall, the M4 Carbine remains a versatile and effective weapon, integral to modern military operations.
