ALD Coatings for Moisture and Corrosion Protection

Even the most advanced materials can fail when exposed to moisture, oxygen, or harsh operating environments. For industries that rely on high-value components — from medical implants to aerospace sensors — these failures can be catastrophic. Atomic Layer Deposition (ALD) provides a reliable defense through nanometer-scale barriers that dramatically improve corrosion and moisture resistance.

The Problem with Conventional Barriers

Traditional coating techniques often struggle to protect 3D surfaces, microchannels, or complex assemblies. Small imperfections, pinholes, or uneven thickness can lead to localized corrosion, delamination, or electrical leakage — all of which shorten product life and reliability.

The ALD Solution

ALD forms ultra-dense, pinhole-free films that act as impermeable barriers against gas and moisture diffusion. By depositing materials like Al₂O₃, TiO₂, or HfO₂, ALD coatings effectively seal surfaces, interfaces, and edges where corrosion typically begins.

These coatings are:

• Conformal: Evenly cover internal features and high-aspect-ratio structures.

• Low-temperature compatible: Safe for sensitive materials like polymers or organics.

• Chemically stable: Resistant to oxidation, acids, and humidity exposure.

• Thin yet powerful: Functional protection at nanometer-scale thicknesses.

Applications in the Real World

• Medical Devices: Barrier coatings for sensors and implants that must remain biocompatible and corrosion-free.

• Energy Systems: Moisture barriers that extend the lifespan of batteries, fuel cells, and flexible electronics.

• Defense & Aerospace: Protective layers against oxidation and plasma exposure in high-stress environments.
