6 Major Applications of Thermal Spray Coating
Most metals are vulnerable to rust when exposed to environmental elements. Applying a rust-resistant coating to these surfaces can prevent oxidation and extend the lifespan of metal components. However, it’s crucial that the coating be smooth and not interfere with the proper functioning of the components.
Among the various coating processes available, thermal spraying is one of the most popular methods. This industrial technique involves melting metallic or ceramic materials and depositing them onto a surface, creating a protective barrier. Thermal spray coatings have a wide range of applications across several industries. Below are some of the most common uses:
1. Metallic Structures in the Oil Industry
Metal equipment such as pipelines and machinery in the oil industry are frequently exposed to harsh, oxidizing environments. Thermal spraying helps protect these metal structures from corrosion. While various metals can be used in the coating process, aluminum is often the preferred material due to its excellent corrosion resistance.
2. Wind Power Production Units
The turbines used in wind energy production are prone to oxidation, especially in outdoor environments. To prolong their operational lifespan and resist rust, a zinc or aluminum alloy is applied via thermal spraying. This coating forms a protective layer that acts as a barrier against corrosive elements.
3. Semiconductor Manufacturing
Semiconductor production involves highly corrosive processes that can damage equipment. Ceramic thermal coatings are commonly used to protect both the semiconductor chips and the chamber components that house them. Given the complexity of materials used in semiconductor manufacturing, custom thermal coatings are often required to meet specific needs.
4. Aerospace Applications
In the aerospace industry, thermal spraying is particularly important for the hot sections of jet engines. These engines must endure extreme temperatures and are highly susceptible to corrosion and fatigue. A thermal spray coating provides an additional layer of protection, allowing these components to survive in such demanding environments.
5. Automotive Industry
Thermal spray coatings are widely used in the automotive sector to protect parts like cylinder bores, piston rings, and alternator covers. These coatings improve the wear resistance and performance of the components. Depending on the part, different metals may be applied in multiple layers to protect the surfaces from both environmental and mechanical stressors.
6. Medical Devices
In the medical field, implants are often sprayed with porous coatings that facilitate fixation and reduce the need for bone cements. Titanium is a common choice for these coatings due to its biocompatibility, meaning it doesn’t react negatively with bone or soft tissues.
Conclusion
Thermal spray coatings have become an integral part of modern industry, enhancing the durability and performance of metal products. They are used not only to protect new surfaces but also to repair worn or damaged ones. With a variety of coating materials available, the right option depends on the specific application and environmental requirements.
