Title: Innovations of Roger N Johnson

Introduction

Roger N Johnson is a notable inventor based in Richland, WA (US). He has made significant contributions to the field of technology, holding a total of 5 patents. His work primarily focuses on advanced methods of coating and deposition techniques.

Latest Patents

One of his latest patents is a method of coating the interior surface of hollow objects with a diffusion coating. This innovative method involves using a filament that extends through a hollow object and is adjacent to its interior surface. The filament is coated with a material in a vacuum, and an electrical current is applied to heat the filament, allowing the coating material to transfer to the interior surface. The filament remains electrically isolated from the object during this process. The coating materials can include a variety of elements such as Ag, Al, Au, and many others. Additionally, this invention allows for the formation of nitrides, hydrides, or carbides of the coating materials by introducing a partial pressure of nitrogen or hydrogen within the vacuum.

Another significant patent by Johnson is a method and apparatus for electrospark deposition (ESD). This method utilizes electrical variable waveforms as feedback parameters to control the ESD process. It involves measuring peak amplitudes from electrical energy pulses delivered to an electrode tip, which correlates to the contact force between the electrode and a workpiece. The apparatus includes an electrode tip connected to an electrical energy wave generator and a high-speed data acquisition card, optimizing the contact force based on feedback signals.
