Process

Platinising of any precious metal substrate (titanium, niobium, tantalum, zirconium require sophisticated equipment and expertise, and none of our competitors offer comparable services. NESPL have developed various surface preparations such as
- chemical surface preparations
- mechanical surface preparation
- and thermal surface preparations etc.
All these surface preperations were performed in inert atmospheres, and developed plating processes that are cost-effective even when complex masking is required.

NESPL performs the following operations on the substrate material before plating

1. abrasive blasting
2. acid etching
3. water washing
4. distilled water rinsing
5. air drying
6. platinizing of the substrate material
7. hot air drying
8. cooling

According to the thickness of platinum deposition the process methodology will differ slightly.

Types of the substrate materials we handle:

• niobium substrate (plate, rod, mesh, tube, strip, wire, perforated plate)

• tantalum substrate (plate, rod, mesh, tube, strip, wire, perforated plate)

• zirconium substrate (plate, rod, mesh, tube, strip, wire, perforated plate)
