Latest Patents

Among his latest patents, two stand out for their significant impact on the industry:

1. **Diffusion Bonded Nickel-Copper Powder Metallurgy Powder** - This invention introduces a novel approach to creating nickel-copper compositions. Unlike traditional methods that mix alloying powders with starting powder metallurgy compositions, this patent proposes a diffusion bonded nickel-copper precursor additive that allows for a direct, one-step addition to the master blend composition. Such innovation not only reduces segregation and dusting but also improves the mechanical properties of the resulting compact.

2. **Method and Composition for Dispersing Extra-Fine Nickel Powder** - This patent outlines a composition designed for use with alloys that include extra-fine nickel powder. The composition features a hydrophobic inorganic dispersant, preferably high-purity silica treated with hexamethyldisilazane (fumed silica). This innovative method prevents the agglomeration of nickel powder, mitigating weaknesses in alloys formed with the nickel powder, such as steel.
