Professionals whose livelihoods depend on the strength of their equipment know how important firm, durable metals are, and the consequences when the equipment breaks.
You also know that treating industrial parts with processes such as metalizing vs. HDG (hot-dip galvanizing) is more reliable and less expensive than having the parts replaced time and time again when they break.
But how do these processes actually work? And which one enhances metals better in the majority of circumstances than the other? Let’s review each of these types of protective coatings to find the best fit for your project.
How Metalizing Compares to Hot-Dip Galvanizing
What is Metalizing?
Metalizing an industrial part begins with abrasive cleaning. Then, melted zinc powder or wire is applied onto the part through compressed air or combustible gases.
Unlike hot-dip galvanizing, where the metal’s temperature increases while dipped in molten zinc, the metal’s temperature stays the same during metalizing. This means that your industrial part will not become warped or deformed in the treatment.
Metalizing mechanically bonds a hard coating to your part, making the part stronger. And, the industry standard is that metalizing helps prevent corrosion for at least 50 years.
What is Hot-Dip Galvanizing?
Hot-dip galvanizing, or HDG, is the process of strengthening a metal part by dipping it in molten zinc. It’s as simple as it sounds.
First, the steel is cleaned of dirt and soaked in an acidic solution to remove mill scale. Then, the part is lowered into a flux of molten zinc aluminium chloride mixed with lead and cooled in a quench tank.
This process creates a coating of alloy layers over the surface of the metal part, protecting it from wear and damage.
The Verdict: Which Protective Coating is the Best Option?
HDG is very useful for improving the durability of industrial parts for long periods of time. However, metalizing builds a purer coating, allowing you to specify the alloy bonding to your desired thickness. Plus, the low heat process keeps your metals safe from deformation during the treatment.
