Electroless Nickel NanoDiamond is a nanocomposite where nanoscale diamond particles are codeposited within a nickel–phosphorus (NiP) matrix using an autocatalytic electroless process. Unlike lineofsight methods, electroless deposition achieves conformal, uniform coverage on complex geometries—including impeller blades, cyclone bodies, screen components, valve trims, pins & bushings, and hardtoreach ID/OD surfaces—often without postgrinding.

Business outcome: longer component life, fewer changeouts during planned shutdowns, improved availability, and meaningful TCO savings across the minetomill value chain.

Why it excels in mine duty:

• Antiploughing hardness: nanodiamond reinforcement blocks abrasive microcutting by hard ore particles.
• Low friction / antigalling: reduces adhesive wear in loaded interfaces (pins, bushings, shaft/seat contacts).
• Corrosion resistance: NiP chemistry engineered for acidic/alkaline slurries and process reagents.
• Uniform thickness: targeted ~7–50 μm; maintain tolerances across complex shapes and tight clearances.
• Chromefree alternative: aligns with modern EHS expectations while meeting performance targets.

Crushing & Comminution

• Challenge: Coarse ore and tramp steel cause severe abrasion and impact, while contact interfaces suffer galling during load.
• ENND fit: Apply to ancillary wear faces, seating interfaces, fastener seats, and feed/transfer surfaces where low friction and abrasion resistance prevent microwelds and scuffing.
• Result: Smoother assembly/disassembly, fewer scarrelated failures, and lower downtime in shutdown windows.

Slurry Pumps & Hydrotransport

• Challenge: Erosive slurries attack impeller leading edges, throats, and wear plates; chemical formulation can accelerate corrosion.
• ENND fit: The diamondreinforced surface resists erosive microcutting, while NiP chemistry withstands acidic/alkaline media. Uniform coverage maintains hydraulic efficiency.
• Result: Longer mean time to failure (MTTF), stabilized pump performance, reduced spares and maintenance labor.

Chutes, Hoppers & Transfer Points

• Challenge: Sliding abrasion, hangups, carryback, and frictioninduced buildup drive extra cleanouts.
• ENND fit: Lowfriction surface with abrasion resistance reduces hangups and carryback, enabling cleaner flow.
• Result: Fewer blockages, higher throughput consistency, less manual intervention.

Screens & Screening Media

• Challenge: Highfrequency vibration and particle impacts cause edge wear, panel seating damage, and throughput drift.
• ENND fit: Thin, conformal coatings protect edge/contact zones and fast interfaces without changing deck tolerances.
• Result: Extended panel life, faster changeouts, stable screening performance.

Cyclones & Classification

• Challenge: Highvelocity slurry generates turbulent erosion at inlets, apexes, and body sections.
• ENND fit: Uniform thin film on complex internal geometry slows erosive attack and preserves design clearances.
• Result: More consistent cut points, longer intervals between rebuilds.

• Coating family: Electroless Nickel NanoDiamond (NiP + nanodiamond)
• Typical thickness: ~7–50 μm (engineered to the duty cycle and clearance requirements)
• Surface behavior: low friction, antigalling where boundary lubrication dominates
• Wear resistance: resists abrasive microcutting and erosive edge wear in slurries
• Corrosion behavior: NiP matrix tuned for acidic/alkaline process streams and reagents
• Deposition: conformal on complex geometries with tight thickness control; minimal postprocessing in many cases
