DENICHELATION

Deltar has a dedicated denickel-plating-only plant that ensures that only the deposited nickel film is removed without damaging the surface of the part in any way and without the need for subsequent machining.

This processing does not require sandblasting or use of acid solutions. A single plant dedicated only to denickelating machined parts, of any material, without altering the characteristics of the base material.

Denickel plating of a component or part is performed for various reasons, which may vary depending on the specific needs of the industry or manufacturing process. Here are some of the main reasons:

Correction of Production Errors:

In some cases, nickel is misapplied or over-applied to a component during nickel plating processes. Denickel plating allows this unwanted layer to be removed without having to discard the whole part, reducing waste and costs.

Restoring the Original Specifications:

In certain applications, particularly in precision applications such as in aerospace or precision engineering, even a small variation in coating thickness can affect part performance or compatibility. Denickel plating allows the part to be restored to its original specifications.

Preparation for a New Coating:

If a component is to undergo a new coating or plating process, it may be necessary to remove the old nickel layer to ensure optimal adhesion and integrity of the new coating.

Reduced Maintenance and Repair Costs:

Instead of replacing expensive parts entirely, denickel plating allows components to be repaired and reused, helping to reduce overall maintenance and repair costs.

Recovery and Recycling:

In contexts where metal recovery is important, such as in e-waste management, denickel plating is a crucial step in separating and recycling nickel and other valuable materials.

Modification of Surface Properties:

Nickel changes the surface properties of an object, such as corrosion resistance or aesthetic appearance. Removal of this layer may be necessary to change these properties or to reduce problems such as live corrosion.

Regulatory Compliance Needs:

As environmental and safety regulations evolve, some industries may require the removal of nickel coatings to comply with new environmental regulations or standards.

Environmental and Economic Considerations

Efficient execution of denickelination, as in the case of Deltar’s dedicated plant, not only helps solve these technical problems, but also helps reduce the environmental impact associated with the use of harsh chemicals and waste generation. The choice of a less aggressive and more controlled method for nickel removal reflects a growing awareness of the importance of sustainability in industrial processes.
