leptanie nereze

[michal lukac]

No prave na panel to nema byt.....na privesky, a tomu farbeniu som sa chcel 
vyhnut.
ale aj tak dik za odpovede..... sksusim to vyleptat v Fe2Cl3

hodne o chemickom dokoncovani je na www.finishing.com ak by to niekoho 
zaujimalo....

napr. http://finishing.com/72/76.shtml
Electrolitic colour for SS(Ni/Cr 18/8):

H2SO4........1 lit
Na2Cr2O7......7,5 gm     (ma toto nejaky nazov?)
7o-95 C/o,o6 A/dm2-1,3V,object=anode,cathode=lead   -> ale tomuto moc 
nerozumiem: 7o-95 C/o ...:(((

Colour sequence:brown-blue-yellow-redish brown-purple-green. -> a tomuto 
tiez... :((



alebo pre leptanie napr......

--------------------------------

Well you can use 1:3 solution of HCl with water and use a rectifier with low 
D.C. current of 6 volts with s.s the cathode and the work piece as anode 
then check for the depth required. Good luck.

etching stainless steel

  for microstructure use marbles reagent
  200 cm of water with 40 g of copper(11) sulphate in 200 cm of HCl (35%)
  for stock removal use a ferric chloride mix consisting of
  11 gallons of 60% ferric chloride
  10 gallons of HCL
  and 4 gallons of nitric but be careful ferric chloride is a pitting agent

Zdravim,

 jeste je mozne panel gravirovat jak mechanicky tak i laserem.
 Pripadne pak vyplnit barvou. Oboje vypada pomerne dobre.

 Hledejte "gravirovani laser"
