Has anyone of you tried to bond anodically Pyrex (or another glass) to Ferrous
alloys (Fe-Ni-Co or Fe-Ni) ?  I was told that it was possible with a prior
oxidation of the alloy.  Do you think it's true ?  Do you have practical
information about the preoxidation treatment that is needed ?     Do you think
that a good surface state (roughness etc...) can easily be obtained with ferrous
alloys ?

Thank you in advance !
