Electrical discharge and surface erosion

[Siggy_G]

Just came over this article. What a brilliant illustration of surface erosion due to electrical discharges.

"Surface degradation occurs as a result of the charring of the material by electrical discharge."

And:

"Certain ion species can concentrate in physical crevices and induce more rapid corrosion"

Then look at these images:

Also, here's an example that a crater and branches comes first, and rivers and water placement as an effect:

Very nice finds Siggy, very nice indeed.

Cheers, Dave.

Now that's the kind of evidence that could make a person believe in the EU model of planetary scarring by electrical discharge machining. Great post Siggy.

* Details and comments on Siggy's first link above:
* The blue streamers ["tracking"] in the first image below apparently started on the left and hit the surface of the circuit breaker spout on the right, where the closely spaced blue zig-zags are apparently where the spout surface eroded, forming the gouges seen in the second image below.

1. Extensive tracking within a cast resin circuit breaker spout.

2. Partial Discharge activity on cast resin circuit breaker spout.

* This image seems to suggest that streamers between planets during ancient close approaches must have been numerous in a similar way, forming the long rilles, rather than individual streamers doing so. Each individual streamer would apparently form a small portion of a rille. But the number of streamers and the length of rille that each one could form would probably depend on several factors, such as planetoids' radii of curvature, surface conditions, charge differences, strength of electric fields etc.
* Does anyone agree that the gouge resembles a crater chain, as well as a rille? I've seen rilles that have a lot of craters, sometimes chains of them.

Lloyd, what let you to the conclusion that the discharges started at the ball and end at the spout wall, rather than the other way around? Based on "hole" theory, I might argue that the discharge began simultaneously on both surfaces.

Great find Siggy,
There is a lot to discuss here and i'll be back to add further agreement with webolife's input on dual directional, but first a note on tracking.
"Carbon Tracking" along pre-established paths was a common problem inside distributor caps on automotive installations, this was 80's info when i was in school of that industry. I wonder if there is common considerations to this that you mention and down through the range of energies (automotive), to the much smaller which i'm encountering in my experiments? (CRT, electric-wind and sandwiched-plates) You can see the more subtil forces at work in the electric-wind experiments which form the trenches, craters and chains - depending on movement. There is a lot to discuss here.
I hope this will attract the attention it deserves. From the subtil to the extreme, the same features are created and electrical activity is behind it all. I'd bet that the pioneers of electricity usage saw the connections and implications that modern disiplines either overlook or ignore.
Great find! d....z
