How Plasma Spray Powders Work
While you’re at the airport, take a look at the airplanes waiting at the gates. Or, if you’re in a city with many skyscrapers, walk around the building and look upward. We bet you’re wondering how they’re protected from they’re protected from a number of factors. For example, how do the parts of an airplane survive the excessive heat they generate? Or, how does a skyscraper keep its brilliance through extreme weather and conditions like humidity and torrential rain? Besides being built for sturdiness, the other way this they are protected is through the plasma spray process.
The plasma spray process is not a simple task, nor is it inexpensive. However, it’s complexity and cost have an enormous Return on Investment (ROI) for the longevity of airplanes, buildings, and other structures. Companies like Jas Energy perform this by using a heat transfer process. It requires a high-KW electric arc transferred to a plasma-forming gas that’s directed through flow-enhancing nozzles which produce plasma spray powders. Once it is all heated to nominal temperatures on average of 10,000 degrees Fahrenheit, the ceramic or metallic powder is then injected into the exit plume. The powder is plasticized in the hot gas and propelled at high velocities to the part’s surface.
There are advantages to this process over other, lower-temperature processes. As mentioned above, plasma spraying can be sprayed at a very high melting point for materials such as refractory metals like tungsten or ceramic elements such as zirconia. In another example, plasma sprayed coatings are generally known to be much denser, stronger, and cleaner when completed. And, because it has such as wide range, plasma spray is one of most versatile.
But is this process right for you? In the end, you need to consult with a plasma spray company to find out. Request a free consultation to determine what can be done for your business and how much it can cost. Ask hard questions to learn what the company can and cannot do and what the ROI will be for your company. Finally, ask others in your industry if they have utilized the plasma spray process in the past and what were the results.
