Title: Buel D Napier: Innovator in Engine Component Technologies
Introduction
Buel D Napier is a notable inventor based in Columbus, IN (US), recognized for his contributions to the field of engine component technologies. With a total of 2 patents, he has developed innovative methods that enhance the performance and durability of internal combustion engine parts.
Latest Patents
One of his latest patents is the Plasma Nitride Chromium Plated Coating Method. This method provides a way to form a wear-resistant coating for internal combustion engine component parts, ensuring that they remain dimensionally stable under severe operating conditions. The process involves a two-step method where the engine part is first coated with chromium to create a base layer. Subsequently, the chromium-coated part is subjected to a reactive gas plasma in a reaction chamber at elevated temperatures and under an applied electrical potential. The nitrogen gas reacts with the chromium to form a chromium nitride surface layer, making it particularly suitable for fuel injectors.
Another significant patent is the Ceramic to Metal Brazing method. This innovative technique allows for the formation of extremely strong ceramic-to-metal joints, which are especially applicable in the creation of components for internal combustion engines. The method simultaneously brazes a ceramic to a metal while normalizing the microstructure and achieving desired mechanical properties in the metal during a single heating step. The ceramic is metallized, an appropriate alloy is applied, and the composite is heated to approximately 160°F to 1750°F for about one hour before being gas quenched in nitrogen or argon.
