Title: Innovations of Robert D Field
Introduction
Robert D Field is a notable inventor based in Los Alamos, NM (US). He has made significant contributions to the field of thermal barrier coatings, holding a total of 6 patents. His work focuses on enhancing the performance and durability of coatings used in high-temperature applications.
Latest Patents
One of his latest patents is a method for forming a thermal barrier coating. This innovative system yields a thermal barrier coating with excellent adhesion to a bond coat overlying a metal superalloy substrate. The adhesion is improved by forming a mature alpha-alumina (Al2O3) scale at the bond coat-TBC interface. The desired mature alpha-alumina scale can be achieved through several steps, including preoxidation of the bond coat at specific temperatures and durations, inoculation of the bond coat surface, surface doping or alloying, and the addition of noble metals. These steps promote the formation of alpha-alumina while preventing the formation of less stable alumina phases, resulting in a more spallation-resistant thermal barrier coating system.
Another significant patent by Robert D Field is a method for manufacturing thermal barrier coated articles. This method involves applying a metallic bond coating on a superalloy substrate, surface doping the bond coating with elements such as Fe, Cr, and Y, and then applying an insulative ceramic coating. This innovative approach is particularly useful for manufacturing articles intended for use in gas turbine engines.
