With its unique position in the field of rare earths, niobium has become a hot spot in the market for many years. The largest user of the metal neodymium is neodymium-iron-boron permanent magnet materials. The advent of NdFeB permanent magnets has injected new vitality and vitality into the high-tech field of rare earths. NdFeB magnets have a high magnetic energy product and are called contemporary: "King of Permanent Magnets", which is widely used in electronics and machinery industries for its excellent performance. The successful development of Alpha Magnetic Spectrometer indicates that the magnetic properties of NdFeB magnets in China have entered the world-class level.é’• is also used in non-ferrous materials. Adding an aluminum alloy or a magnesium 1.5 to 2.5% neodymium, can improve the high temperature properties of the alloy, airtightness and corrosion resistance, it is widely used as aerospace materials. In addition, the ytterbium-doped yttrium aluminum garnet produces a short-wave laser beam, which is widely used in the industry for the welding and cutting of thin materials having a thickness of 10 mm or less. Medically, yttrium-aluminum garnet lasers are used instead of scalpels for removal surgery or disinfection of wounds. Tantalum is also used for the coloration of glass and ceramic materials as well as additives for rubber products. With the development of science and technology, the expansion and extension of the field of rare earth technology, the element of strontium will have a wider use of space.
Metal alloy powders are commonly used in thermal spray processes to coat surfaces with a protective or functional layer. These powders are typically made by combining different metal elements in specific compositions to achieve desired properties such as corrosion resistance, wear resistance, or thermal conductivity.
Some commonly used metal alloy powders for thermal spray include:
1. Nickel-based alloys: These alloys are known for their excellent corrosion resistance and high-temperature strength. They are often used in applications where resistance to oxidation and wear is required, such as in gas turbine components.
2. Cobalt-based alloys: Cobalt alloys are known for their high hardness and wear resistance. They are commonly used in applications where resistance to abrasive wear and high temperatures is required, such as in the aerospace and power generation industries.
3. Stainless steel alloys: Stainless steel alloys are used for their corrosion resistance and high-temperature strength. They are often used in applications where protection against corrosion and oxidation is required, such as in chemical processing equipment.
4. Titanium-based alloys: Titanium alloys are lightweight and have excellent corrosion resistance. They are commonly used in applications where a combination of high strength, low density, and corrosion resistance is required, such as in the aerospace industry.
These metal alloy powders can be applied using various thermal spray techniques, such as flame spraying, arc spraying, plasma spraying, or high-velocity oxygen fuel (HVOF) spraying. The specific choice of alloy powder and thermal spray process depends on the desired coating properties and the application requirements.
