Latest Patents

Martinengo's latest patents include a process for sintering silicon nitride compacts. This innovative method involves sintering a silicon nitride compact with a density of at least 1.3 g/cm³ in a nitrogen gas atmosphere at substantially atmospheric pressure. The compact is embedded in a protective powder that may consist of silicon nitride, boron nitride, or a mixture of both, along with one or more sinterization additives. These additives are present in the protective powder in an amount ranging from 3 to 20% by weight. Another significant patent focuses on producing protective coatings on metals and metal alloys. This process entails coating a workpiece with a slurry in acetone and cellulose acetate, which includes a powder of average grain size between 0.5 μm to 10 μm, containing aluminum and possibly chromium, along with a small quantity of cerium or yttrium hydride. The workpiece is then heated in a non-oxidizing environment to facilitate the diffusion of metals into its surface.
