dear all
i have treated a rusty campagnolo front hub by putting its parts in a phosphoric acid solution. The rust is gone, but the surface of the bearing cones has many tiny holes now and i think that will probably deteriorate over time when put under load, along with the ball bearings.
is it possible to fix them ?

this surface looks safe

this one however looks heavily damaged, i tried to polish it gently but it looks hopeless


this is the cone of the rear hub which has been in use and didn't rust.
