Gold Coatings in Industry
Electrical, chemical and optical surface functions from thin gold layers.
Why this topic matters
Electrical, chemical and optical surface functions from thin gold layers. Gold is normally used only where its particular surface, electrical, optical or chemical behaviour adds enough value to justify the material.
How gold fits the system
Industrial manufacturing places controlled amounts of gold through plating, vacuum deposition, bonding and microfabrication.
Material tradeoffs
High material cost rewards precise deposition, but too little gold can increase porosity, wear-through or functional variability.
Manufacturing and quality
Thickness, composition, adhesion, roughness, pattern fidelity and process capability are core quality variables.
Lifecycle and recycling
Gold-bearing targets, filters, residues, wire ends and rejected parts are valuable manufacturing recovery streams.
