Thermal spraying technologies have been around for nearly 40 years, but within the last decade or so the technological capabilities have grown significantly. Metal finishers are now able to produce truly high-performance coatings from a wide range of materials and for a variety of applications. Thermal spray finishing can be applied to anything from electronics to heat engines. At Secoa Technology, we are dedicated to providing you with high quality, reliable metal finishing services. We have a skilled and knowledgeable team that is able to provide you with consistent coatings for all of your finishing needs.
The Process
The basic steps in applying a thermal spray coating include:
- Part preparation
- Masking and fixturing
- Coating
- Finishing
- Inspecting
Usually, thermal spraying involves the spraying of molten material onto a part in order to provide an ultra-fine-grain finish. The material being sprayed onto the part comes in a powder form and is melted in a flame to form a fine spray. The most common flames are oxy-acetylene or hydrogen based. The molten particles are accelerated by the flame and impact onto a metal surface that has been prepared for finishing. The molten powder solidifies quickly in order to form the coating. When done properly, the part being finished is kept at a relatively low temperature in order to avoid compromising the component. In this case, the thermal spraying process is known as cold processing.
Advantages of the Thermal Spray Process
The main advantage of this spray process is that it allows for a large choice in coatings. A wide range of materials can be processed in powder form, so you have more choices on the type of coating you would like to have on your part. This process is limited only by materials that require a higher melting point than the flame can provide or ones that are compromised when they are heated.
