Yes, an ALD chemical barrier coating can protect a component from certain chemicals while adding only a precisely controlled, nanometer-scale film. That makes Atomic Layer Deposition a strong option for parts with tight clearances, small internal passages, detailed surface features, or dimensions that a conventional thick coating could disrupt. The coating material and process still […]

If a polymer component needs a thin protective barrier but plasma exposure could alter the surface, a plasma-free Atomic Layer Deposition process may be the better route. Plasma-free ALD for polymers uses sequential vapor-phase chemistry to build a conformal film without exposing the part to the reactive species and radiation associated with a plasma step. […]

ALD coating inside stainless steel tubes and small bores is possible because vapor-phase reactants can reach surfaces that line-of-sight coating methods cannot. The process builds a thin film through sequential, self-limiting surface reactions. As a result, the coating can follow an internal passage without substantially changing its diameter. However, uniform coverage depends on several factors. […]

Atomic layer deposition can be used on many temperature-sensitive polymers, but the process must be tailored to the exact material and finished component. The polymer’s glass transition temperature, dimensional stability, surface chemistry, outgassing behavior, and response to the chosen precursors all matter. Low-temperature ALD for polymers works best when the process is developed around the […]

If you’re determining how to ship prototype parts for ALD coating, protect two things: the physical component and its surface condition. Confirm the project details with the coating provider before packing anything, avoid placing adhesives or cushioning directly against critical surfaces, immobilize each part inside clean packaging, and include enough documentation to identify every component […]

The coating method often determines whether a thin film solves the problem or creates a new one. Whether you are protecting a satellite component from atomic oxygen, sealing a microfluidic channel against aggressive solvents, or adding a moisture barrier to sensitive electronics, the coating method directly affects performance, lifetime, dimensional tolerance, and cost. For harsh […]

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 […]

Choosing the right thin-film deposition process is critical when performance, geometry, and materials compatibility are at stake. While PVD and CVD have long been industry standards, Atomic Layer Deposition (ALD) has emerged as the go-to solution for high-precision applications that demand perfect conformity and control. A Quick Comparison Property PVD CVD ALD Film Uniformity Moderate […]
