Title: Innovations by Robert C Bill
Introduction
Robert C Bill is a notable inventor based in Rocky River, Ohio, who has made significant contributions to the field of turbomachinery. With a total of seven patents to his name, he has focused on enhancing the thermal shock resistance of ceramic layers used in gas-path seals.
Latest Patents
One of his latest patents is a method of fabricating an abradable gas path seal. This invention aims to improve the thermal shock resistance of a ceramic layer, particularly in turbomachinery applications. The design features an improved abradable lining that is deposited on a shroud, forming a gas-path seal. The innovation involves the deliberate introduction of 'benign' cracks, which are microcracks that do not propagate significantly under thermal shock conditions. Laser surface fusion treatment is employed to create these microcracks, resulting in a continuous dense layer that cools and solidifies, forming a fine crack network. This network helps prevent catastrophic cracking during thermal shock exposure.
Another significant patent by Robert C Bill is related to laser surface fusion of plasma sprayed ceramic turbine seals. Similar to his previous invention, this patent also focuses on improving thermal shock resistance through the introduction of microcracks. The methodology and benefits are consistent with his earlier work, emphasizing the importance of thermal shock resilience in turbine seals.
