This is a continuation of the previously posted Sportsmatic 5 mod.。
The plating on the old watch is peeled off、Some brass is exposed。
This time Sportsmatic 5 also、Under the plating is a metal such as brass、By peeling off the plating, blue rust and green rust occur.、There were issues such as rashes。
Together with installing the screw-down crown、I thought about fundamentally reviewing the case、I tried coating with an oxide film due to black rust。
In the first sportsmatic I made、I made the black lighter and made it a gun metallic color.。
Unlike painting、Hard to peel off and no film thickness、It has a glossy finish。
By coating brass with black rust、Can stabilize the surface、Prevents the occurrence of blue rust, etc.。
I'm about to make Unit 2 with a golden case.。
First of all, a patina that causes black rust(Electrolyte)Soak in。
After a while、In black!
It seems that you are looking at magic tricks even though it is a clear liquid。
Take it out of the patina and wipe it、Lightly oil。
Unit 2 is、I tried to make it as black as possible。
It will be a color like this。
Unit 2 is still under construction、1I tried side by side with the unit。
That the、Succeeded in black rust coating。
The chemicals are different depending on the metal、It seems that there are various patinas other than stainless steel.。
The black rust coating is also interesting if the brass case is left with a tattered plating case!
SHUKU's Hello。
Um、Most of them are amateurs who don't understand、If you combine a green light bulb with the red lens cover of a foreign car, it will give you an orange color and you can use it as a turn signal!?
YOSHIPI-'s
That's right。
Than the green light bulb of the turn signal of the foreign car、It may be similar to dyeing the blinker lens to make it smoke w
(Hard to understand the example?)
Blue rust and green rust erode metal and make holes.、Black rust is rust that hardens the surface and does not corrode.。
There are some tools that are blackish iron, right?
It is an image of doing the same thing as that in the case。
In a broader sense, it's the same oxide film as blueprint.。
So it turns blue while it turns black w
I'm wondering if I'll make a dial with that next time。The dial is mostly brass!
Good evening SHUKU。Gobusatashiteorimasu、I am always amazed by the wonderful ideas and techniques.。Is this the same as converting red rust on a car to black rust??Even if the principle is the same, if the conversion agent is applied from the top, only the surface will be oxidized, and after a while, red rust will reappear from the back, sadly.。If it's electrolytic, it's beautiful black rust. 、I only know Saint Paul Mekki (laughs).
Mitsuru
Good evening!
This black rust is not red rust conversion、Electrolyte and oxidize...sorry、I don't understand enough to explain to people。
Polished to the pure state of brass before turning to black rust、Degrease and remove oil、Soak in electrolyzed water。Originally a technology for surface treatment of metal parts on the edge of stained glass、It ’s a liquid called Patina.。
on the other hand、There is also a liquid called bluing that black rusts the surface treatment of the gun.、It seems that imports became impossible a few years ago、I was looking for a good drug。
I'm also interested in sun pole plating。I'm thinking of trying。
SHUKU's
Congratulations for the completion。
Case processing for screw-in crown! It's wonderfully cool 👍
I also want to challenge black dyeing, so I will refer to it.。
Earth's、Good evening!
Black dyeing is deep ...、The principle is difficult。
In the first place, it seems to be quite difficult to start from a place where you do not know what material the case is made of。
I thought the bezel wasn't brass、Blackened with brass chemicals。It's quite a mystery w
By the way, I also tried pickling stainless steel.、It didn't change at all, so when I left it for about 3 days, it turned uneven blue.
After all it is a mystery。
