With a total of three patents to his name, Dubal has made significant advancements in processes that enhance the efficiency and safety of heat treating methods.

Latest Patents

One of Dubal's latest patents is a "Method for recycling heat treating salts." This innovative system focuses on recycling heat treating salts, such as nitrates and nitrites, from a rinse bath. It includes mechanisms to prevent the excessive build-up of impurities like carbonates or chlorides, which can impair heat treat efficiency. For instance, carbonates that form in a nitrate-nitrite quench bath and chlorides carried by drag-out from a chloride heat treating bath are effectively removed by concentrating the rinse water, eliminating undesirable components from the concentrate, and returning molten rectified salt to the quench.

Another significant patent is the "Cyanide-free carburizing process and composition." This process involves a cyanide-free molten salt carburizing method that utilizes an alkali metal salt bath covered with finely divided graphite particles. The bath operates at temperatures ranging from approximately 1550°F to 1900°F and is equipped with mechanical agitation to facilitate air entrainment and carbon diffusion into the surface of the immersed parts. The total graphite content in the bath is maintained between about 1.5% to 7%, with a preference for synthetic graphite to minimize ash content.
