Thermal Spray Coating Services

Thermal spray coatings are a versatile surface enhancement that are used in a variety of industries and applications to improve wear or corrosion resistance or restore dimension. Generally speaking, thermal spraying involves heating finely sprayed metal or ceramic feedstock and projecting it onto a substrate, where the coating material cools and densifies. These metal and ceramic coatings can be applied to a wide range of materials, including metal alloys, ceramics, and even plastic and composite materials. In addition, the thickness and composition of the sprayed layer can vary depending on the requirements of the application. Some common uses for thermal spraying include corrosion barrier coatings of aluminum on steel parts, hard tungsten carbide surfaces on high-wear machinery, and hard, corrosion resistant ceramic coatings on industrial pump and valve components. Furthermore, thermal spraying is a relatively cold process, when compared to welding, allowing coatings to be applied with minimal distortion to sensitive components.

Thermal spray is a process used to apply coatings, such as metals or ceramics, onto surfaces. This is done using an aerosol of molten particles or a high-velocity stream of solid materials, which are then projected onto the target surface through a combination of heat and pressure. Thermal spray coatings are mechanically adhered with the individual particles cooling and locking into the roughened surface to which they are applied.

The most common type of thermal spraying is plasma spraying. In this process, an electric arc is used to heat a stream of inert gas to very high (plasma) temperatures, which then melts the particles of the coating material. This molten material is then sprayed at high speeds, where it rapidly cools and adheres to the target surface.

There are many different types of thermal spraying, each of which uses different materials and techniques to create the desired results. Some of the most common forms of thermal spraying include plasma spray, high-velocity oxy-fuel spraying or HVOF, flame spray, arc wire spray and spray & fuse.

Most metals and ceramics and some plastics can be applied by thermal spraying. Common coating materials include metals such as stainless steel, titanium, cobalt and nickel superalloys, and various other pure metals and blends. Other thermal spray materials include ceramics, plastics, and composites. The composition of these coatings can be customized based on the needs of the application, and different materials can be combined at the time of spraying to create specific coating results.

These coatings are highly durable, which makes them ideal for use in harsh or aggressive environments where traditional metal components would wear or corrode over time. They are also resistant to heat and corrosion, so they can withstand the stresses of high temperatures or chemical exposure without losing their protective properties. Additionally, these coatings can be customized to suit a range of different needs. Whether you need to protect an engine from wear and tear or a large industrial machine from corrosion, thermal spray coatings have the potential to provide outstanding results. So if you're looking for an effective way to improve the life of your mission critical machinery or other equipment, consider the economical addition of a thin and durable thermal spray coating.
