Last time I checked rust is a combination of particular elements that causes a minor chemical reaction:
The main ingredient here is water or humidity... so yeah it is physical damage, RUST just don't magically appear...
I've had overall good customer service from EVGA, but I can see how they tighten things up after people start taking advantage or abusing their warranty program.
Rust is the name of iron oxides of different colors, usually red or black, that form when iron or steel corrodes.
What causes rust is the reaction of iron with oxygen dissolved in an electrolyte, usually it's rainwater, condensing water from the atmosphere or freshwater.
The corrosion of iron and steel is an electrochemical reaction, it means that there is an exchange of electrons between the metal that is oxidized and corrodes and oxygen that is reduced.
There are always two different reactions in a corrosion process:
1) oxidation of Iron
2Fe ---> 2Fe2+ + 4e-
2) reduction of Oxygen
O2 + 4 e- + H2O ---> 4OH-
The overall reaction is:
2Fe2+ + 4OH- ----> 2Fe(OH)2
Fe(OH)2 reacts further with oxygen to form Iron oxides: Fe2O3 (hematite, red rust), Fe3O4 (magnetite, black)
The main ingredient here is water or humidity... so yeah it is physical damage, RUST just don't magically appear...
