AURUNA® 313 Gold Iron Electrolyte
AURUNA® 313 Gold Iron Electrolyte
Cobalt-free alternative to direct gold plating of stainless steel
The highly effective, strongly acidic gold electrolyte AURUNA® 313 enables direct gold plating of stainless steels with good adhesion. It is particularly suitable for chromium-nickel steels, molybdenum- containing steels and nickel-based alloys that are difficult to activate. Thanks to its activating effect, AURUNA® 313 can also be used successfully for other passive materials that are difficult to electroplate. If necessary, activation can be supported by special pre-treatment measures.
Base metal intermediate layers and a reduction in corrosion resistance are avoided. The electrolyte is free of chloride or fluoride and is suitable for both decorative and technical applications. It has a large operating range and is suitable for rack, barrel and reel-to-reel applications.
The coatings made of AURUNA® 313 are crack-free, ductile and non-porous. They can be deposited brightly up to a coating thickness of 0.5 μm. The deposition speed is sufficient to economically deposit the desired coating thickness directly from the electrolyte in many cases. The coatings retain their bright appearance.
