AI Servers Need More Than Chips: Surface Treatment Is Key to Liquid-Cooling Parts
AI-era cooling systems are demanding. The stability, corrosion resistance and cleanliness of stainless tubes, manifolds and fittings in the coolant path are key to sustained compute performance. MAPT uses chemical polishing, passivation and sealing to bring surfaces to their optimal state.
Chemical Polishing: The Key to Stable AI Liquid-Cooling Components
AI-server liquid-cooling components demand far higher surface cleanliness and corrosion resistance than standard parts. MAPT applies mature chemical polishing before passivation to help cooling tubes, manifolds, and fittings reach superior performance.
What Is Zinc-Nickel Alloy Plating? A Complete Guide
- Zinc-Nickel plating deposits a zinc alloy containing roughly 12-15% nickel, far outperforming standard zinc coatings - With trivalent chromium passivation it withstands 720+ hours of salt spray without red rust — up to 2,000 hours in high-spec processes - It is the go-to finish specified by global automakers for engine-bay and chassis fasteners
