Steel might be a robust material, but it’s weakened by moisture and abrasion. Coatings can prevent corrosion while protecting the metal beneath. There are several excellent options:
Electroless Nickel Plating
This is a lasting nickel-phosphorus alloy coating applied through a chemical process without the need for electrolysis. It achieves an exceptional hardness level and corrosion resistance. It’s capable of precise, complex layers of uniform thickness, so it’s a great option for the aerospace, automotive, and electronics industries. Businesses such as //www.swmf.co.uk/surface-coatings/electroless-nickel-plating/ offer a range of plating options and thicknesses.
Hot-Dip Galvanisation
This method adds a zinc layer through immersion. It achieves a lasting, rust-resistant bond that can last 50 years. It’s highly resistant to abrasion and can be used to protect corners and interior spaces.
Power Coating
This dry finishing process is baked in a thick layer. It adds chip and scratch-resistance to outdoor furnishings and car components that don’t require a precise design.
Zinc Plating
This method is otherwise known as electrogalvanasing. It applies a thin zinc layer through electrolysis, so it’s often used for small hardware such as nuts and fasteners. Black Oxide can be used for the same application, but it alters the surface rather than coating it. For this reason, it only offers low rust resistance.
Steel is prone to many different kinds of wear, particularly when exposed to cold or damp environments. Coatings can address flaws, but each option has its own pros and cons. There is no perfect coating, only the perfect coating for a particular application.
