Alonizing

<p>Alonizing is a <a href="/facts/Diffusion/KbAxroBa">diffusion</a> <a href="/facts/Metallizing/QI5cN9EP">metallizing</a> process in that it is a <a href="/facts/Thermochemical/fQS7IsoT">thermochemical</a> treatment that involves enriching the surface layer of an object with one or more <a href="/facts/Metal/PT8hNX6R">metallic elements</a>. Specifically, alonizing is the diffusion of <a href="/facts/Aluminum/7wmR8jYE">aluminum</a> into the surface of a base metal through high temperature vapors. The types of metals that can be alonized include all types of wrought and cast <a href="/facts/Steel/aN6qWo4H">steels</a> (i.e. plain carbon and low alloy grades, <a href="/facts/Allotropes_of_iron/deRQ3dBM">ferritic</a> and <a href="/facts/Austenite/Fzp52xYc">austenitic</a> steels, highly alloyed nickel-chromium steels, etc.). This process results in an <a href="/facts/Alloy/I7w7WQWR">alloy</a> with the surface properties of aluminum while retaining the base metal's inherent <a href="/facts/Strength_of_materials/CE77cUcB">strength</a> and <a href="/facts/Stiffness/xlabLkfT">rigidity</a>. Therefore, alonizing does not change the high-temperature mechanical properties of the base metal, which is the advantage of alonizing over simply creating an <a href="/facts/Aluminum_alloy/1EzR3Y4t">aluminum alloy</a> (aluminizing the surface versus aluminum throughout the alloy).
