SURFACE TREATMENT FOR SEAL ASSEMBLIES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18199249 titled 'SURFACE TREATMENT FOR SEAL ASSEMBLIES
Simplified Explanation
- The patent application is about seal assemblies for turbomachines. - The seal assemblies consist of stationary and rotating components with at least one interface between them. - Some examples of the seal assembly include an oleophilic coating between the stationary and rotating components. - The seal assembly may also have a surface texture to enhance the oleophilicity of the coating. - Other examples of the seal assembly include an oleophobic coating between the stationary and rotating components. - The seal assembly may have a surface texture to enhance the oleophobicity of the coating. - The oleophilic features of the seal assembly retain lubricant between the stationary and rotating components. - The oleophobic features of the seal assembly prevent the escape of lubricant from the contact regions between the stationary and rotating components.
Original Abstract Submitted
This disclosure is directed to seal assemblies for a turbomachine. The seal assemblies include stationary and rotating components and at least one interface between the stationary and rotating components. In some examples, seal assembly includes an oleophilic coating disposed between the stationary and rotating components. The seal assembly may include a surface texture to enhance the oleophilicity of the surface coating disposed between the stationary and rotating components. In other examples, the seal assembly includes an oleophobic coating disposed between the stationary and rotating components. The seal assembly may include a surface texture to enhance the oleophobicity of the surface coating. During operation, the oleophilic seal assembly features retain lubricant between the stationary and rotating components and the oleophobic seal assembly features inhibit the escape of lubricant from the contact regions between the stationary and rotating components.
