Nanoceramic Coating for Wear and Corrosion Resistance

Technology Overview

An innovative company has developed a novel nanoceramic coating that provides high hardness, wear and corrosion resistance, and low friction to fast moving parts in environments with high wear or elevated temperature.

This technology is superior to anodising or plasma electrolytic oxidation (PEO). It does not require pre-treatment, performs better on complex shapes, and the resultant structure is denser with no pores and high homogeneity. The resulting hardness (twice that of chrome) and low roughness thus allow for less polishing needed.

Manufacturers of machinery in various sectors such as textiles, packaging, aerospace, food, motor sport and luxury goods with large volume demands, are sought for commercial agreements with technical assistance, and licensing.

Technology Features & Specifications

The technology comprises of a patented process for nanoceramic coating on metals and functionalization of ceramic surfaces.

The process is an electrochemical treatment with a proprietary colloidal alkaline electrolyte which combines the oxidation of the substrate metal with the co-deposition of the electrolyte material.

The process requires no pre-treatment and only needs a simple clean-rinse, thus producing no hazardous effluents or gases.

Potential Applications

Some of the potential applications of the technology include:

  • Packaging and textile machinery
  • Aerospace, marine, automotive, transportation and engine parts
  • Luxury items and high value consumer goods
  • Food and medical industry

The coating is suitable for aluminum, magnesium, titanium, zirconium, niobium and their alloys.

Customer Benefits

Compared to anodising and plasma electrolytic oxidation, the coating is more homogenous and pore-free, and has lower surface roughness. Overall it has:

  • Higher hardness
  • High corrosion resistance
  • Very high wear resistance
  • Higher dielectric strength
  • Higher thermal conductivity

The process also requires no pre-treatment (clean-rinse only) and can be applied to complex shapes. This means that the technology is more environmentally friendly, and produces harder, smoother and longer lasting components with less effort.
