Sanova-Polytech, Inc. had created a new family of patented Liquid Induction Thermochemical Processes (LINTERPROCESS) and production equipment LINCARB-1, which was used to create quickly and inexpensively corrosion resistive diffusion austenitic surface layer on some grades of construction and tool steels by carbon saturation of metal surface in special harmless cold Liquid Active Medium (LAM). Obtained high carbon austenite has a good stability to elevated service temperatures up to 600 C. The coating can be made during several minutes simultaneously with some types of heat treatment that increase significantly mechanical properties of the products being processed, i.e. their durability and longevity. The equipment for this treatment has a computerized automatic controlling system, which provides equal quality of each treated part, and can be installed in automatic line or production cells. The innovative technologies are ready for wide implementation in manufacturing of any suitable steel, cast iron or powder metallurgy product.
