In general on vehicles, a high corrosion rate would be near 2mm/year. This rate is for vehicles that are near an ocean and the roads are heavily salted for an extended winter.
One factor would be, what was in the explosives that hit these parts? There may be chemicals that are FAR MORE...
JAC270 45/45 is a steel that had galvaneel (zinc) on both sides. The 45 is the weight of the galvaneel. If the part is for Honda, contact them and they will give you all the of the details.
Can anyone give me an example of a conductive rubber being in contact with aluminum causing corrosion/pitting of the aluminum? (Assuming no other metallic contact, maybe salt water exposure, temperature range of -40 to 250 degrees F)
I have a decent amount of corrosion understanding, but not...
Sacrificial anodes are all over your car already. Galvaneel (like NickE mentioned) is a zinc layer that is on any good car body (I won't mention the names of the companies that don't use it!)
For the sacrficial anode to work, you need ELECTRICAL connection between your anode and the part...
Some basic corrosion acceleration methods are cycling in and out of salt water (usually 5% salt), cycling high (95%) and low (20%) humidity, and cycling temperature.
