: The metal part is "packed" into a mixture of aluminum powder, an activator, and an inert filler, then heated in a furnace. This causes the aluminum to diffuse into the surface, creating a protective aluminide layer .
To (or aluminize in American English) means to coat a material—typically steel or another metal—with a protective layer of aluminum. This process is primarily used to enhance a material's resistance to corrosion, high-temperature oxidation, and wear. Core Methods of Aluminising
: "Aluminised" fabric is used in fire proximity suits and gloves to reflect radiant heat away from the wearer.
: Used in exhaust systems and heat shields because it reflects heat and resists rusting better than standard steel.
: Components like turbine blades and engine parts are aluminised to survive the high-temperature oxidation found in jet engines.
