Title: Petya M Georgieva: Innovator in Brazing Technologies

Introduction

Petya M Georgieva is a notable inventor based in Oviedo, FL (US), recognized for her contributions to brazing technologies. With a total of 6 patents, she has made significant advancements in the field, particularly in the development of braze alloy compositions for superalloys.

Latest Patents

Her latest patents include innovative methods for brazing superalloys. One patent describes a multi-component braze filler alloy that comprises at least 70% by weight MarM509A superalloy, which is diffusion brazed to a CM247 alloy base substrate. This method is particularly useful for components such as gas turbine blades or vanes. The research indicates that higher braze temperatures can lead to improved results, including the potential for re-welding the brazed component, allowing it to continue in commercial service. Another patent focuses on a braze filler alloy containing 60-70% by weight CM247 superalloy and BRB braze alloy, which can be diffusion brazed to a CM247 alloy base substrate. This method ensures that the substrate/braze interface can be weld-repaired without de-melting the braze alloy, making the component solidification crack resistant and repairable for future defects.
