Roger Johnson Perkins, Deceased

Title: The Innovative Contributions of Roger Johnson Perkins

Introduction

Roger Johnson Perkins, a notable inventor from Evandale, OH, made significant contributions to the field of materials science. He is best known for his innovative patent related to hard facing alloys. His work has had a lasting impact on various industrial applications.

Latest Patents

Perkins held a patent for a "Process for hard facing a substrate." This invention involves applying a hard facing alloy to a substrate's surface by creating a mixture of at least two constituents with different solidus temperatures. One constituent has a solidus temperature above the substrate's processing temperature, while the other is below it. The mixture is prepared by pressing and lightly sintering the constituents in powder form, allowing it to retain its shape for attachment to the substrate. The substrate is then heated to the processing temperature, enabling interdiffusion of the phases to achieve a homogeneous hard facing alloy composition.

Career Highlights

Throughout his career, Perkins worked at General Electric Company, where he contributed to advancements in material applications. His innovative approach to hard facing alloys has been recognized for its practical applications in various industries.

Collaborations

Perkins collaborated with notable coworkers, including Murray Sawyer Smith, Jr. and Joseph Carl Wukusick. Their combined efforts in research and development have furthered the understanding and application of hard facing technologies.

Conclusion

Roger Johnson Perkins was a pioneering inventor whose work in hard facing alloys has left a lasting legacy in materials science. His innovative processes continue to influence the industry today.
