An engineering research team at the University of Alberta identifies a new material for coatings that offers promise for high-temperature applications like hydrogen combustion engines.
The newly developed alloy — AlCrTiVNi5 — has superior thermomechanical properties. It includes high stability, low expansion, fracture tolerance, and a valuable combination of strength and ductility. This makes it able to stand up in high-heat and high-pressure environments.
The coating is made from a new super alloy composed of metals such as aluminum and nickel. The new material is known as a complex concentrated alloy. It is ideal for coating surfaces that must withstand high temperatures. It includes such as in gas turbines, power stations, vehicle and airplane engines.
