... of thermal spray coatings. Coatings are used for different reasons such as abradable coatings that are applied to provide tight clearance control between compressor blades and shrouds. The tight clearance control helps maximize engine efficiency. Thermal barrier coatings such as yttria partially stabilized...

..., a proprietary bond coat is applied to the composite before applying a top layer of molybdenum, vanadium, stainless steel, or tungsten. Until now, the need for heavy shielding or a requirement to continually replace the abraded surface sections meant composites were not an option. This coating can extend...

... with the rest of the coating. It can occur when the mount medium is softer than the coating and abrades faster than the coating. It can also be caused by highly resilient polishing papers that yield excessively into pores and along edges, increasing the polishing rate in those locations. The addition of Al2O3...
