Steam and Land-Based Turbines
Steam and land-based turbines also owe their operating efficiency to Metal/Thermal Spray.
The video below shows a HVAF system spraying a WC-Co-Cr coating being applied on-site onto steam turbine blades in order to protect them from droplet erosion.
Almost every component of the gas turbine engine has some type of coating on it to prevent the damage caused by wear and temperature. HVAF and HVOF coatings are used in the hot section of the engine to coat the shroud with high temperature metals that will not damage the edge of the engine’s turbine blades, yet provide the tight clearance necessary for the engine to function properly. HVAF and HVOF coatings are also applied to the rotating sleeves or bearing found in the hot section of the engine. Common coatings used in this application include T-800 and Chromium Carbide Nickel Chrome coatings.
The above video shows a Kermetico HVAF AK7 spraying Tungsten Carbide on a turbine floor.
Wind Turbines
Wind turbine towers are exposed to harsh external environments, particularly those in an offshore location. A corrosion resistant coating of Zinc is applied both manually and also on automated production lines.
The above video shows the zinc Arc spray coating process of wind towers (turbines) from blast, thermal spray zinc, prime and top coat.
