Latest Patents

One of Walker's latest patents is the "Zirconium alloy heat treatment process and product." This innovation focuses on producing zirconium-base alloy channels and fuel cladding tubes that exhibit unique resistance to accelerated pustular corrosion in boiling water reactor environments. The process involves a heat treatment that causes segregation of intermetallic particulate precipitate phases in two-dimensional arrays, preferably located along grain boundaries and subgrain boundaries throughout the alloy body.

Another significant patent is the "Coating system for superalloys." This protective coating system is designed for nickel-base and cobalt-base superalloys, providing oxidation and corrosion resistance at elevated temperatures. The superalloy body is first coated by physical vapor deposition with a composition that includes chromium, aluminum, and elements from the rare earth group. Following this, the body undergoes an aluminizing overcoating to enhance corrosion resistance.
