Title: Innovations of James A. Bell: Pioneering Metal Matrix Composites

Introduction: James A. Bell, based in Oakville, CA, is an accomplished inventor with a remarkable portfolio of 24 patents. His innovative work largely focuses on processes relating to metal matrix composites, which have significant applications in various industries due to their superior strength and lightweight characteristics.

Latest Patents: Among his latest contributions to the field, two patents stand out prominently. The first, titled "Method of forming metal matrix fiber composites," provides a sophisticated process for fabricating metal matrix composites. This method involves a multi-step process where fibers are initially coated with nickel using either electrodeposition or gaseous deposition techniques. Subsequently, aluminum is over-plated onto these nickel-coated fibers, again using electrodeposition in a non-aqueous electrolyte or gaseous deposition, ultimately resulting in aluminum-coated-nickel-coated fibers. The final product is achieved by sintering this composite under compression, which forms a nickel-aluminum matrix that minimizes voids while incorporating extended, unbroken lengths of fibers.

His second recent patent, "Method of preparing porous nickel-aluminum structures," outlines a process for fabricating porous aluminide articles. This method entails plating a preform with nickel and aluminum to develop a metal-plated structure. The nickel plating is achieved through electrodeposition or gaseous plating, while the aluminum is deposited via gaseous deposition of an organometallic-aluminum compound. The resulting structure undergoes reactive sintering, producing a robust nickel-aluminum structure that features exceptional porosity and strength, with excellent oxidation properties exceeding 400 degrees Celsius.
