Blame Avatar's night scenes or maybe the new 'Nids, but I wanted to go a different direction with corrosion for a project.

The plan is to create corrosion for some of the odd birds (ceramite, adamantium, armorplas, etc) that are standard material in Imperial vehicles or to reflect unusual toxic conditions. Since regular iron rust goes through browns, reds, & oranges, I wanted to take a stab at the blue side.

My apologies for the chartreuse mapping on the test, but you get the idea. Basically, it is just a switch on what you would do for any AFV burn, but with blue pigments instead of the normal palette. I was thinking that adding purple into the mix might even be good as a replacement for brown oxide. Right now i'm using a dark blue-green for that.

Whatcha think? Any ideas?

what no busts?:dont-know: dam suckered me in:rotfl:. Any way the rust looks very good, would stick with what you have it works well

Corroding other materials, intriguing.

Think it's hampered by our own lack of experience in seeing other materials corroded like that. For me, looking at the pic, I don't see the surface that way cos I ain't got a visual reference stored in my head as a precedent. Instead I see a blue surface with orangey corrosion on it cos I have seen that before and fits more with my internal reference library. Or something.

I agree with this, or possibly cobalt corrosion or something you'd see from an undersea wreck (microbial).

it looks nurgleified (My made up word) to me rather than corroded.
however these invented materials would degrade, however and in whatever colour you wanted them to I suppose, however plastic would, I would expect just erode away, and ceramics the same but slower....
stage 1, loss of sheen
stage 2, minor erosion to exposed areas
stage 3, heavy erosion
stage 4 the start of disintegration
over 1000 years or more
just staying the same colour with dirt & moss or exotic plant life growing on it


But I do like the paint job.....

 

[freakinacage]

i think it looks great and i agree with tercha about the disintegration of ceramics etc. maybe the timeline could be decreased for very harsh conditions though

aluminum cannot rust, copper cannot rust. Rust is defined as Iron Oxide.

Copper ends up with a blue green patina as it oxides.

What you've got, looks almost like lichens (odd plant that grows on bare rock)have started growing on it. Needs a bit more white spattered in.

Here is another quick panel sans mapping & in a happy imperial grey. I went lighter on the corrosion vs complete & used purple similar to what I'd do regularly do with brighter orange pigments.

Feedback appreciated.

It looks like oxidization, it looks odd. You really are 'maxing the envelope' here.

I think I need to go and think about it before an answer???

 

[Chrome]

It looks like oxidization

With that simple statement I'd say it is a complete success since all manners of 'rust' is in fact an oxidisation. It's just that we are not used to see it that way. ^^

I found this looking for corrosive effects on different materials:
Be warned, it is Google translated.
Corrosive effects

 

[cassar]

be careful with your oxidents

when good ideas go wrong, less is more lol

Hmmm semantics really,
Aluminium can corrode - aluminium oxide - which is a white powder and as such forms a protective layer to the aluminium underneath.

Of course you stated that copper can corrode as well.

as can steel, stainless steel, iron (in all its forms) Brass, lead, etc etc

Even the superb Titanium corrodes

I believe generally the use of the term "Rust" the meaning is "Corrosion"

if you don't want corrosion then build in Gold, Platinum, Rhodium, Palladium and Irridium.

@Tercha: which still corrodes given the right circumstances, they are just very unlikely to do so.

 

[jerry kurl]

Your examples look great - i remember digging up stuff like this when i was a kid the blue green is spot on (old batteries often turn stuff this colour if buried in damp soil)

Any chance of a tutorial

i new i had seen this stuff somewhere before, add soda crystals or the stuff they use for snow to make it look real as though the armours starting to degrade into powdery residue

The second pic looks pukka. The illusion of non-ferrous corrosion works a treat there, reckon in part due to an absence of orange. The orange in the first pic sparked a mental connection to rust, over-riding the illusion. of the intended corrosion effect.
Like, a base of red grass, we could buy that as alien - but a patch of red grass amongst some green would see our mental reference regard it as a patch of bloody grass instead of something alien.

Cheers for broaching the non-ferrous corrosion topic. I got some Necromunda scenery in the offing the ideas explored here will help a treat with.
That powdery build up idea of Cassar's with snow effects sounds like something to give a go. We have precedent of that so it'll work in our head. Could be nifty on ceramite.

It's really the same path to rust as what's detailed in FAQ & I'd assume FW's model book covers this as well. You would just flip the colors. I'll see if I can piece something together though.

There is an outstanding tutorial on basic rust principles here: http://ultrawerke.blogspot.com/2007/08/rust-painting-tutorial-with-pigments.html .

i new i had seen this stuff somewhere before, add soda crystals or the stuff they use for snow to make it look real as though the armours starting to degrade into powdery residue

You can use CA/PVA & baking soda or Vallejo putty, crackle paste, etc to get corroded finishes pretty easily. Maybe throw in some pitting with a Dremel and build up around the edges with your residue of choice. Acid pitting from 'Nids could be a good project for that type of thing.

 

[Ghudra]

Here is a really quick shot at some corrosive pitting.

 

[freakinacage]

oooh very effective, how did you do it? with the dremel?

and can you reccomend a decent crackle? the stuff i have seen so far either crackles too little or you have to slather it on too thick
