Direct gold plating solution on steel and titanium alloys
Color: 24 karat yellow
Application: bathtub uses
Description of the process:
The AURUFORM 311 process is an acidic solution (with or without cobalt) that acts as a primer for stainless steels and titanium alloys that are difficult to gold plate. This initial layer of gold facilitates the subsequent operations of instant or micron color plating and guarantees long-term durability.
Working conditions for using the AURUFORM 311 product:
This product is a two-part product, first pour AURUFORM 311 starter electrolyte solution, which is a 250 ml concentrate, into a Pyrex beaker and add distilled water to a volume of one liter. After mixing it completely with water, the GOLD SOLUTION CAP solution, which contains gold, is added to the solution. It is worth mentioning that in order to use this product in higher volumes, it should be poured into polypropylene (PP) tubs and used according to the following table:
| parameter | unit | scope of work | The optimal amount |
| Gold concentration | (gr/L) | 0.8-1.5 | 1 |
| Free acid concentration | (gr/L) | According to the analysis | – |
| pH | – | 0.5-1.0 | – |
| plating time | (Second) | 15-40 | 25 |
| temperature | (°C) | 40-45 | 40 |
| Voltage | (V) | 2-4 | 3 |
| Current density | ampere per decimeter | 0.5-2 | 1 |
| Plating speed | microns per minute | 0.05-0.8 | 0.06 |
| Andes | Ti/Pt | – | – |
| Stirring/filtration | Centimeters per second or liters per minute | strong | – |
