  • Process for forming an improved durability thick ceramic coating
    Patent number: 9725797
    Abstract: A process for forming a ceramic coating on a substrate, such as a turbine engine component includes the steps of providing a substrate, creating a plasma which preheats the substrate, and forming a ceramic coating by injecting a powder feedstock into the plasma. The ceramic coating forming step comprises depositing ceramic particles having a mean size in the range of from 100 to 150 microns at constant particle morphology.

  • PASSIVE TERMPERATURE CONTROL OF HPC ROTOR COATING
    Publication number: 20130136864
    Abstract: A method and fixture for holding a part being spray coated at an elevated temperature by placing the part between a base forming an insulating cover and an upper insulation board. The space therebetween forms an area for positioning a part to be sprayed. The cover and board are sized to retain heat in the part at a steady predetermined temperature when the part is spray coated. The part is heated for sufficient time to uniformly bring the part to temperature, followed by applying a spray to coat the part.
