experiencing Babbitt bearing material "pick up" when running against a steam turbine shaft journal coated with 13Cr steel (via arc spray). Coating was finish ground and polished and applied within all normal parameters. surface of coating appears normal, ie. no excess porosity and bearing material has not marked the coating surface either.
bearings were blued against shaft and checked for clearence prior operation yet we still had bearing seizure.
