Battery technology has always been a tough challenge for researchers: on the one hand they need to try their best to keep the cost of manufacturing batteries down and give the batteries a satisfactory endurance, on the other hand to keep the batteries safe, They are located in the consumer electronics equipment often used on weekdays, which means that an accident such as a battery explosion should never happen because it may cause serious harm to the human body.
Despite the rare accidental cell phone explosion, but lithium-ion battery charge fire, or explosion accident is not never happened. The good news is that recent Stanford researchers said they have developed a new lithium-ion battery that gives the battery a "fail-safe" protection.
Researchers in the new battery covered with a layer of plastic layer, which contains nickel particles, when the battery is hot, it will cut off the current itself, when the battery temperature back to a safe level, they began to supply power for the device. This will prevent the battery from exploding due to overheating.
"People have tried different ways to deal with a lithium-ion flash fire." The research team member said: "We designed the world's first to be able to prevent battery overheating without sacrificing battery life Battery on fire. "
The key to this new technology is that the battery is capable of breaking its own current and then powering it back on itself. Although some lithium-ion batteries are capable of cutting off the current before the battery explodes, they can not be restarted and powered on.
However, this technology is still only present in research experiments, want to really applied to the phone, may also need to wait a few years. Researchers need to prove that the technology is safe and secure, and that its costs can be accepted by smartphone makers for mass production.
Tungsten carbide mixed Metal Alloy Powder is commonly used in PTA (Plasma Transferred Arc) welding. PTA welding is a process that involves the deposition of a hardfacing material onto a base metal to provide wear resistance, corrosion resistance, and improved mechanical properties.
Tungsten carbide is a very hard and wear-resistant material, making it ideal for applications where high abrasion resistance is required. It is often mixed with other metals, such as nickel, cobalt, or chromium, to form a metal alloy powder. These metal alloys enhance the properties of the tungsten carbide and improve its compatibility with the base metal.
The tungsten carbide mix metal alloy powder is typically fed into the PTA welding torch, where it is melted and propelled onto the surface of the base metal using a high-energy plasma arc. The molten powder forms a hard, dense coating that bonds with the base metal, providing excellent wear resistance and protection.
The specific composition of the tungsten carbide mix metal alloy powder can vary depending on the application requirements. Different ratios of tungsten carbide and other metals can be used to achieve desired properties, such as hardness, toughness, and corrosion resistance.
Overall, tungsten carbide mix metal alloy powder is a versatile and effective material for PTA welding, offering superior wear resistance and protection for various industrial applications.
