Is there solid evidence that this is actually possible, as opposed to creating a layer on top of it? The only people I've ever heard suggest that it's possible were talking about cast iron pans, and it's always struck me as the sort of thing that would have major implications for a lot of other fields.
I tried some web searches before posting this, still not finding anything suggesting it's possible other than cast iron pan aficionados.
- BikiniPrince 6y agoYes, this isn’t a mystery. There are lots of coated steel products that use the crudest of coatings that need grinder off. Unless the material is polished to a high shine it will absorb oil.

- ethbr0 6y ago"Soak into" is probably an engineering approximation converted to lay language. What we're really talking about is surface-gap-filling. So yes, "into" at some level of magnification. "Onto" at another.
- BikiniPrince 6y agoIndeed! I was avoiding describing the surfaces at high detail .

(Note: more relevant and profitable to study in the context of machinery / engine design)

- hosteur 6y agoWow that Wikipedia page reads like an ad.
- Crazor 6y agoyeah oilite is a great bearing material, but it‘s not exactly „normal“ metal, but sintered bronze. In essence, you clump together bronze powder with a binder and then heat it up until the binder is gone and the powder has stuck together. What‘s left behind is kind of like a sponge, which enables impregnation with oil. Very special process and nothing to do with metal always having „pores“ or anything where oil can seep in
