Until all the rebar is gone. Rebar is just low grade steel with next to nothing in it to prevent rust. After a surface coat of rust gets on it (2-3 days) it will slow the process but it will never stop. Rebar is normally set inside concrete which also slows down the rusting but if you break open any concrete slab with rebar in it you will see it has rusted.
Better still, avoid the problem in the first place. If you don't want to see rust, don't use steel. use composite (FRP) rebar. this is manufactured from glass-fibre based composites and is used where steel can not or should not be used.

What should I put for a hypothesis for unrusting metal with electricity?
There is no one definitive answer to this question. Some possible hypotheses that could be explored include: using electric current to prevent metal from rusting, using electric current to reverse the rusting process, or using electric current to promote the formation of a protective layer on metal that prevents rusting.
How do you prevent roofing nails from rusting off?
The nails should be covered by the shingles or caulk. They should not be rusting.
What is rebar detailing?
Rebar Detailing is a procedure of making shop drawings for the steel reinforcement for the development procedure. The Rebar Detailing procedure incorporates the position, bending shapes, amount, description, laps of the reinforcing steel and measurements. The Rebar Detailing Drawings are made to incorporate the separating, area, rebar size and lap of steel. The Rebar Detailing Services includes: Rebar Detailing Services, Rebar Shop Drawings Services, Rebar fabrication Services, Rebar Framing Plan Design, Rebar Structure Foundation, Rebar Pit Design, Rebar Framing Plan, Rebar Beam Design, Rebar Structure Steel Detailing, Structure Foundation Rebar Detailing.

How do you repair a gunite pool with exposed rebar before replastering or should you tear it out and rebuild it?

Rebar submitals where can you go to get them?
Typically there are two types of submittals for rebar. the first is placing drawings. These drawings will act as a set of instructions for fabrication and installation of the rebar. These drawings can be created and supplied by the rebar fabricator or a specialized outside detailer can provide them for you. The second is the actual product data which indicates the mill the material came from, its chemistry composition and production information. For this, the fabricator or supply house you purchase the rebar from should be able to supply you with the sheet data you need. Both the placing drawing and material data sheets will be submitted to the architect and engineer of record to review and verify that the rebar conforms with their intent and design.

How do you patch or seal an exposed rebar post tension cable in foundation slab?
Rebar and Post Tension cable (PT) are two entirely different items. Rebar is the static steel bars placed in the concrete while the PT are high tensile strength cables that were placed in concrete than stressed under hydraulic jacking to a tension generally around 2500 to 3500 psi. As a result, the situations for repair are different. The exposed rebar can be cleaned and patched through approved methods. However the PT should be looked at by a professional as it is an integral part of the structure and, as mentioned before, is under tensioned stress. If the exposed rebar is in a PT slab, caution should be used and a professional consulted as well, due the rebar being integrated with the PT.
