Latest Patents

One of his latest patents is a method for resistance braze repair. This innovative technique allows for the joining or repairing of metallic components, including superalloy components such as turbine vanes and blades, using a high electrical resistivity brazing alloy composition. The method involves introducing the brazing alloy within a substrate defect or between two substrates that need to be joined. An electric current is passed through the brazing alloy until it melts and bonds to the adjoining substrate. The high resistivity of the brazing alloy concentrates heat generated by the current flow in the alloy rather than in the substrate, enhancing the repair process.

Another significant patent involves a turbine abradable layer with asymmetric ridges or grooves. This invention focuses on turbine and compressor casing abradable components for turbine engines. The design features composite grooves and vertically projecting asymmetric non-parallel walls or trapezoidal cross-section ridges that effectively reduce, redirect, and block blade tip airflow leakage downstream into the grooves. The innovative design aims to resist blade tip airflow leakage, thereby improving the efficiency of turbine engines.
