5 Benefits of Black Oxide Coating You Should Know

Do you know you can turn all your rusty bolts and screws into brand new through oxide coating? Black oxide coating or chemical blacking is a metal surface finish that provides increased corrosion resistance and reduced friction coefficient when in contact with other metals. When applied to screws and bolts, it's important to make sure they are compatible with a black oxide coating.

What is black oxide coating?

When black oxide coating is applied to screws and bolts, they must be compatible with the treatment. In addition, the metal surface finish provides increased corrosion resistance and reduced friction coefficient when in contact with other metals.

What happens in black oxide coating?

When your screws and bolts are blasted with media, it creates a porous surface. This allows the black oxide coating to adhere directly onto the metal surface without any issues or contaminants causing problems during application.

Black oxide treating increases corrosion resistance in marine environments where salt is present due to its application on steel surfaces like nuts, washers, bolts, and screws. If you own a workshop, it’s the best kind of DIY to try. Otherwise, you can have black oxide coating services to assist you with. 

Top 5 Benefits of Black Oxide Coating

1. Long term protection

One of the best reasons to use black oxide coating is long-term protection. This metal surface finish holds up for longer periods than other types of coatings, making it perfect in places where corrosion resistance and longevity are important factors.

2. Low cost alternative to hard chrome plating

The black oxide coating is a low cost alternative to hard chrome plating when it comes to protecting screws and bolts. One of the most common uses for this metal surface finish is in highly corrosive environments, where corrosion resistance must be at its highest level for extended periods.

3. Resistant to chemicals

Another great reason for using black oxide coating is its resistance to chemical corrosion. This metal surface finish provides excellent protection against many types of harsh chemicals, which makes it perfect in environments where it's likely that any number of caustic or corrosive substances could be present.

4. Provides increased resistance to wear

Another reason for using black oxide coating is increased resistance to wear. This metal surface finish provides the perfect balance of low friction coefficient with excellent abrasion and corrosion resistance. It makes it great in environments where wearing down or corroding screws and bolts is likely.

How do I know if my screws or bolts can be coated? Unfortunately, not all metals are compatible with a black oxide coating, so it is important to make sure that you know which ones can be coated. Black oxide coating works best on steel screws and bolts, but some aluminum alloys will also work with the black oxide treatment.

How do I apply black oxide coating?

Applying black oxide coatings requires specialized equipment like anodizing tanks or rotary tumblers. If you're looking for a professional, you can call readily available black oxide coating services.

Guide to Steel Nickel Plating – What Should You Know?

Image
  Steel is one of the most extensively used metallic elements in the world, but its intrinsic weaknesses can cause problems for all types of businesses and industries. High preservation prices and susceptibility to rust can be tough to work around, but you can minimalize these difficulties with suitable metal plating solutions. Likewise, hard chrome electroplating on steel, nickel plating on carbon, and mild steel does not change much from other metallic elements. It is ideal to find one of the best metal finishing service providers to take services like carbon steel nickel plating at reasonable prices. Below, I’m going to share some important things about nickel plating on steel that you should know. Can Steel Be Nickel Plated? Rather than use energy, you plunge the steel into an aqueous explanation that uses chemical agents to decrease the nickel ions and enable a statement. The procedure is extremely stable and produces an even nickel covering. That supposed, stainles...

What is Electrolytic Plating and why is it good for your auto parts?

Most industries and auto part companies use Iron and Steel to manufacture their machine components. Summary: Most industries and auto part companies use Iron and Steel to manufacture their machine components. While iron and steel are strong, they are prone to rust because of their chemical make-up. Technically speaking, oxidation occurs when iron rusts. As a result, the metals corrode, fatigue, and degrade as the rust develops. Zinc is used to cover metal components to slow down the oxidation process and ensure that they last longer. Zinc is also used in the iron and steel galvanizing process, which uses almost half of all zinc mined. Here we are going to discuss in detail about electrolytic plating. Body : What is Electrolytic Plating or Electroplating? It is a process in which metal is deposited onto a conductive surface through an electrochemical reaction. In the simplest sense, it transfers metal from one object to another by passing an electric current through them. It's been ...
