Anodizing
Type I Anodize:
- Boric Anodize 鈥 Boric-Sulfuric Acid Anodize (BSAA) is an alternative to chromic acid anodize (CAA), that builds a thin-film anodic coating and provides corrosion protection and a mechanical bond. This is a chromated, environmentally friendly solution.
- Tartaric Anodize 鈥 Tartaric-Sulfuric Anodize (TSA) is an alternative to chromic acid anodize (CAA), that builds a thin-film anodic coating and provides corrosion protection and a mechanical bond. This is a chromated, environmentally friendly solution 鈥 typically specified in Airbus programs like the A350.
- Chromic Anodize 鈥 Chromic Acid Anodize (CAA) creates the thinnest anodic coating, while providing the same corrosion resistance as other types of anodization, such as boric or sulfuric.
Type II Anodize:
Type III Anodize:
Phosphoric Anodize
- Phosphoric Acid Anodize (PAA) is most commonly used in bonding applications, as it provides a superior porous surface for bonding to composites. It serves as a strong adhesive in high-humidity environments.
Chemical Film or Chem-Film
Nital Etch
- Nital etch is a solution of nitric acid and alcohol, used to etch metals. Nital etching is used to detect overtempering, improper carburization, and re-harding, as well as other manufacturing errors.
Passivate
Phosphate Fluoride
- Phosphate fluoride coating is used to inhibit corrosion, improve paint adhesion and to reduce damage in metal to metal contact applications. In addition, phosphate fluoride can be used in etching solutions, namely for titanium.
Aluminum Etch
- Aluminum etch is a process by which a thin layer of the surface is removed, prior to penetrant inspection, typically in caustic or alkaline baths or solutions. This enhances the identification of surface defects, prior to further processing.
Titanium Etch
Zinc Phosphate
- Zinc Phosphate is a conversion coating for steel and aluminum, comprised of phosphate salts and phosphoric acid. This coating resists corrosion and allows for adhesion.

What Is Zinc Phosphate Coating?聽聽
Zinc phosphate is a conversion coating for steel and aluminum, comprised of phosphate salts and phosphoric acid. This coating resists corrosion and allows for adhesion. In fact, zinc phosphate dental cement has been used widely for crowns, bridges, and orthodontic appliances as well.聽
However, a zinc phosphate coating first begins as a crystallized coating (a powder first) and then after a chemical reaction, the metal and the phosphate form to create the final coating. This means that metals coated with zinc phosphate then have high corrosion resistance.聽
What Is The Difference Between Zinc And Zinc Phosphate?
Zinc phosphate is an inorganic compound that comes in a white powder formulation. Before the use of zinc phosphate, there were other toxic materials in place. However, by 2006, zinc phosphate replaced lead and chromium to be the most commonly used corrosion inhibitor.
Zinc is often used in these processes due to its rust-preventing properties. While zinc phosphate may be a popular coating type, zinc has been used for years on iron and stainless steel products. Depending on the type of coating, zinc acts as a barrier against corrosion. Many call this the zinc patina as it becomes the barrier between a stainless steel product and the elements.聽
What Is Zinc Phosphate Coating Used For?聽
It is used to prevent corrosion. This is done by providing strong adhesion and protection against corrosion. A zinc phosphate coating may be used in: construction, drilling, mining, refineries, and transportation among others.聽
What Is The Zinc Phosphate Coating Process?聽
The process begins by treating the metal with a zinc phosphate solution, which then creates a surface layer of crystals 鈥 this is what protects the metal underneath from corrosion. This layer can either contain finer or heavier crystalline phosphates, which often depends on the method of application.聽
Application Methods – [H3]
- Immersion Process – This is the most common method with a heated bath. This means that you put the item(s) in the bath with the coating and let the electrochemical process occur
- Spray Process – The spray process is another method of application, but it must be done with care to avoid any pickling or other imperfections.聽
How Thick Should The Zinc Phosphate Coat Be?聽
While this will range depending on the material, the coating thickness generally ranges from 0.0002 inches to 0.0006 inches.聽
Benefits Of Zinc Phosphate Coating
Zinc phosphate is a non-conductor but has a variety of benefits to consider including:
- Strong Primer – You can add a zinc phosphate coating as the first treatment layer to provide corrosion resistance for: paints, oils, waxes, and Chemical Agent Resistant Coating (CARC)
- Strong Adhesion & Protection – A zinc phosphate coating provides a strong adhesive and corrosive protection against rust. This also provides better friction for sliding components/parts
- Withstands Many Conditions – As a Chemical Agent Resistant Coating (CARC) used in the military, zinc phosphate coatings provide protection from the harshest of environments
Disadvantages Of Zinc Phosphate Coating聽
Heating phosphates can be difficult to get right, but many of the conceived disadvantages just come down to perfecting the process. Some must deal with a lack of phosphate crystal growth, which is what is responsible for creating that strong outer coating. And others may deal with 鈥渁cid pickling鈥 issues which usually boils down to cleaning and rinsing properly.聽
However, for more on how we go about the zinc phosphate coating at 厂妹视频, and we鈥檒l explain the process from start to finish.聽
How Long Does Zinc Phosphate Coating Last?聽
As it is built to last, a zinc phosphate coating should be able to hold up to a lot. The corrosion resistance and insolubility in water makes it a great choice for high wear applications. Similarly, the melting point of a zinc phosphate coating is 1,650 F which makes it able to stand up to high temperatures as well.聽
聽Is Zinc Phosphate Coating Rust Proof?聽
In general, phosphate coatings are protective against rusting and corrosion. However, much of this depends on proper application because these coatings can be porous when applied.聽
Zinc Phosphate Coating 厂妹视频聽
Metal finishing can be daunting 鈥 there鈥檚 the cost associated and the application methods to consider. However, with nine centers across North America, at 厂妹视频, we serve a global supply chain with the most comprehensive set of processing capabilities and approvals for high-value, mission-critical parts.聽
