Title: The Innovations of William R Barber, Jr.
Introduction
William R Barber, Jr. is a notable inventor based in Portland, OR (US). He has made significant contributions to the field of materials science, particularly in the development of wear-resistant surfaces and drill bit manufacturing. With a total of 5 patents to his name, Barber's work has had a lasting impact on various industries.
Latest Patents
One of Barber's latest patents is for a wear-resistant carbide surface. This innovative surface structure boasts high resistance to impact and thermal shock, making it suitable for a wide variety of tools and implements. The structure is created by bonding carbide particles with a substantially pure copper matrix in the absence of oxygen. This carbide-copper surface can be attached to the working surface of a ferrous tool either during the bonding process or at a later time. Notably, the attachment process can be corrected by quenching the combined tool and surface structure from an austenitizing temperature without damaging the copper matrix. Additionally, refractory sheet materials are utilized to contain the carbide and matrix material during the liquefaction process.
Another significant patent involves a method for drill bit manufacture. In this process, carbide elements are coated with carbide and nitride materials, such as titanium, through chemical vapor deposition. These elements are then cast in molten steel, resulting in a highly effective drill bit product.
