Title: Innovations by Brenda Hoy in Metal Surface Treatment

Introduction

Brenda Hoy is an accomplished inventor based in New Westminster, Canada. She has made significant contributions to the field of metal surface treatment, holding two patents that showcase her innovative approach to solving industry challenges.

Latest Patents

Brenda's latest patents focus on a method for the removal of certain oxide films from metal surfaces. In her first patent, a manufactured metal member, such as a wire, is subjected to mechanical stress to create cracks in the magnetite oxide film that coats it. The metal member is then moved through an electrolysis cell bath, where it acts as the anode, while vertically positioned steel bars serve as the cathode. A pulsating DC current is applied, allowing the current to flow through the cracks in the oxide, which maintains the metal member in a state of depassivation. This process loosens the bond between the oxide film and the metal member, making it easier to clean off the loosened magnetite. Additionally, a thermal stressing step may be employed prior to the mechanical stressing to enhance the effectiveness of the method.
