. Let me say one last time,
there is no dissolving of diamonds or silicon carbide in the
grinding process.

Maybe you can sell your diatribe to Norton, then, because their literature
seems to think there is. But then, what the hell would the leading
manufacturer of grinding wheels know about that?

Diatribe? now you are getting nasty. I don't have a clue
who or what Norton is or says, but if they say diamond
dissolves in iron or steel, then they don't know squat about
physics or chemistry. Any first year (well, maybe 2nd year)

Got me curious. Where's a first-year student when you need one? It
wasn't hard to find references.

U.K. chemistry professor's article, "In any application where friction
is important the diamond-coated tool bit will heat up and, in the case
of ferrous materials (be it the tool substrate or the workpiece) the
diamond coating will ultimately react with the iron and dissolve"

SP3, manufacturer of PCD tooling, "Diamond is unaffected by almost
every other chemical or compound in nature. One exception is hot iron.
The carbon atoms in diamond will dissolve into the iron, quickly
eroding the diamond surface."

Materials science encyclopedia entry for diamond, "Diamond will react
with strong carbide forming metals (i.e. tungsten, tantalum and
zirconium). It dissolves in iron, cobalt, manganese, nickel, chromium
and the platinum-group metals."
