An abrasion resistant coating, also known as a protective metal coating refers to anything from concrete sealants to aesthetic auto paints.
One formulates this kind of wear resistant coating to protect structures found in industrial settings against wear, corrosion and damage brought about by factors such as electrochemical potentials, moisture, heat, and pH.
Examples of abrasion resistant coatings include:
Application of wear resistant coating
When friction grinds, rubs or wears away metal, an abrasion of metal occurs. This abrasion causes a machine or part to not function in its regular use. To protect substrates from harsh environments, you can use abrasion resistant coatings.
You can apply this coating on various areas and structures such as floors, dumpsters, commercial establishments, and industrial plants. Here are some of the benefits and applications that these coatings can offer:
These coatings that offer wear resistance have a massive boost on output capacity and flexibility.
Industrial equipment uses these coatings. These include food processing equipment, automotive parts, medical technologies, and more.
Some specialized coatings, such as PTFE, have non-sticking properties. It makes surface cleaning quicker and simple and, in the process, minimizes overhead expenses. It can prolong a machine’s life and improve its overall quality.
The whole point of using coats that prevent wears is to reduce friction on the metal surfaces. These frictions are what cause the wearing and tearing of the metal surfaces.
Coatings such as PTFE are hydrophobic. It prevents the absorption of water that can result in massive impact when in contact with metallic surfaces.
It, therefore, improves the overall durability of the equipment.
The most commonly used wear resistant coating is polymers. They are used on various applications as listed below:
- Slurry lines.
- Pumps including their casings.
- Roll surfaces
Aside from polymers, one can use some types of protective paints for specific industrial needs. Other than abrasion resistance, they also offer protection to equipment and structures. It facilitates equipment restoration and friction reduction. They include:
- Ceramic epoxy. It offers protection by the ceramic particles bonding with the resin system.
- Air dry epoxy. Being a cost-effective coating, it promotes resistance against corrosion.
- Phosphate. It is a ferrous metal coating that offers protection against minor corrosion and galling.
Application of abrasion resistant coating in industries
You apply a coating for abrasion resistance depending on which type of wear the exposed part can have. For protection against erosion, scratches, and even impact, they require coats containing various abrasion resistant properties.
Some coatings provide superior micro hardness while others provide superior macro hardness and others provide a superior surface finish. Aside from these, different coatings have unique combinations and additional properties such as dielectric strength, non-stick, heat resistance, autoclavability, and chemical resistance.
Some of the coatings used in industrial applications include:
It has a smooth surface finish that protects parts from scratches and wears by providing a low friction surface. It also has excellent mechanical toughness even when the temperatures are high. An additional property that makes it unique from other coatings that offer abrasion resistance is that it is autoclavable.
Due to its surface smoothness, it protects the surface from abrasion. Furthermore, it also contains mechanical properties for impact resistance and offers protection against different types of wear. It also has properties such as good dielectric strength, high purity, and corrosion and chemical resistance. It, therefore, makes it perfect for application on wires and cables.
This kind of coating offers a lubrication layer that helps prevent wear and any impact-related abrasion. It has impact and abrasion resistance due to higher bonding resin levels that increase the coating hardness. Aside from this, they contain additional properties such as temperature resistance, non-stick and chemical resistance. They are usable on original equipment or various OEM components by offering abrasion resistance.
It is a tough coating polymer that you can apply to thin films. Two industries facing the wearing issue use it. These are the commercial and industrial cookware and the automotive engineering industries. It has other properties which offer flame retardancy, dimensional stability, chemical resistance, and thermal stability.
The main characteristic about Epoxy is that is tough and dries quickly upon application. It is capable of enduring exposure to abrasion particles whether fine, large, or coarse. Its application includes parts exposed to oils, corrosion, acids, hydraulic fluids, heating agents, chemicals, and severe impact. It also offers resistance under elevated temperatures.
It offers chemical, ultraviolet, and corrosion resistance. It applies to metal substrates. Commonly used in medical, semi-conductors, and chemical processing industries, it has resistance to several solvents and chemicals.
This type of coating is ideal for use on pump impellers and moving parts of various equipment in chemically aggressive environments. In addition, this coating contains impact strength, unparalleled cut-through resistance, and abrasion that increases its ability to resist wear and tear.
In conclusion, coatings that offer abrasion resistance are of various varieties. They offer great benefits such as cost-saving, improving performance, increasing the machines, lifespan, and reducing maintenance. With nanotechnology, nanocoating can help boost project development and improve business profitability by saving on costs.
How nanotechnology can help in coating offering abrasion resistance.
By using nanotechnology, the development of nano-coatings is possible. It offers the same kind of application as other coatings used to prevent wear. Some of these are the AN Black Low-friction and Wear Resistance Coating that lengthens the industrial life of the part and the AN Anti-fog Coating that prevents condensation of surfaces. There is also the AN Surface Heater Coating offering high energy efficiency rates.
With the help of high vacuum machines, you can use the coating equipment to coat your products and pieces.
With the help of the nanotech industries such as Advanced Nanotechnologies (AN), you can achieve cost reduction and improve the functionality of coatings. You can also receive professional counseling when it comes to nanotechnology. Contact us for more information.
