Of course diamond will dissolve in even stone cold steel. But at what rate? I remember a chemistry teacher explaining have the walls of a glass beaker would dissolve in water. So we set about to figure out how long until a glass of water would eat a hole in the glass and leak. It was a good exercise in scientific notation, it would take a LONG time.
But the diamond problem run faster then you think because the local pressure and temperature at some local microscopic place is HUGE. Even if the average temperer of the steel is only "warm" What meters is the pressure and temperer of the few atoms that are actually in contact not the bulk temperer of the materials. In any case carbide is best for cutting steel, I think because it can be made into a more effective shape with a better angle. Diamons are typically just glued randomly to the end of a bit or blade and the tiny sharp edges are randomly oriented On Thu, Aug 3, 2017 at 10:06 AM, John Kasunich <[email protected]> wrote: > Maybe.... but it definitely will remove a thin layer of the diamond. and > another, and another.... > > > > On Thu, Aug 3, 2017, at 11:55 AM, Stuart Stevenson wrote: >> Would that create a thin layer of casehardening? >> >> On Thu, Aug 3, 2017 at 10:02 AM, John Kasunich <[email protected]> >> wrote: >> >> > It's not room temp when it is scraping across steel at a couple >> > thousand surface feet per minute.
