Wow, shotpeen and its effects are a science in itself.I am guessing through some experiments that the surface compression is causing unpredictable out of round conditions-plastic deformation by shrinking the material.Though there is probably some structural weakening I would like to repair it by...
Can surface compression by glassbead blasting cause plastic deformation on a bronze alloy brg with 12" dia. and .115 wall thickness? Air pressure 100-130 lbs with "H" or 100 size bead.Alloy Cu87%,Al6.2,Fe1.1%,Sn3.2,Zn.7 Thanks for any help in advance.
