Title: Nadine Burkarth: Innovator in Ceramic Core Technology

Introduction

Nadine Burkarth is a prominent inventor based in Courbevoie, France. She has made significant contributions to the field of ceramic core technology, holding a total of 3 patents. Her innovative methods have advanced the processes used in casting, particularly in the aerospace industry.

Latest Patents

One of her latest patents is a method of making ceramic cores for use in casting. This method involves forming a core in a mold through hot injection of a thermoplastic paste that consists of a refractory ceramic composition and an organic fraction. The organic fraction is eliminated through heat treatment, and the core is then heat-treated to achieve the minimum consolidation necessary for handling. The porous structure of the core is impregnated with a solution containing a silica or alumina-based elementary oxide colloid, followed by the elimination of the liquid from the impregnated product.

Another notable patent is a method of making a complex ceramic core for use in a metal casting process of the lost wax type. This core features at least one recess extending into its interior, intended for the manufacture of hollow components with internal cavities and partitions. The process includes successive injections of at least two compounds, one of which is degradable, to create a solid body. The first injection forms a blank, and each subsequent injection adds layers until the solid body is completed. The body is then treated to remove the degradable compound, leaving the desired complex core.
