Heat treatment and thermochemical processing are indispensable steps in creation of machine parts with high core strength and various surface protective coatings, which are necessary for sufficient resistance to load, friction, wear, corrosion, erosion, cavitation, etc. Sanova-Polytech, Inc. has created the scanning LINCARB processing for rapid creation of continuous, local or multipoint diffusion tribological coatings with various thickness, microstructures and properties. The part with permanent section, cylindrical or any other form is immersed in suitable liquid active medium and heated by high frequency current induced in it during moving throughout an inductor. The protective case can be created inexpensively during minutes only both in internal and external surfaces depending on scan velocity, processing temperature, material, liquid active medium chemical composition and physical properties. This technology was used for strengthening of shafts, axles, rolls, pipes, tubes, bushings and similar products, and can be implemented in any US industry.
