sherardizace
Sherardizace, known in English as sherardizing, is a metallurgical surface-treatment process used to apply a zinc-containing diffusion coating to ferrous metals. The coating provides corrosion resistance and improves paint adhesion, and it is particularly well suited for parts with complex geometries where other coating methods struggle to reach internal features.
The process is carried out in a closed rotating container (drum or retort) containing the metal parts,
Materials and coatings: sherardizing is most commonly applied to steel and cast iron. The resulting coating
Applications and history: the technique emerged in the late 19th to early 20th century and has been
