  • Patent number: 4873605
    Abstract: A device for treatment of ferromagnetic materials comprising means for developing a magnetic field of a selected intensity, duration, and cycle, which field is passed through materials to be processed, such as cutting tools and drill bits that have been sharpened or resharpened and other parts that have internal stresses. The magnetic field through the material provides stress relief of the stresses from welding, forming, heating cooling or sharpening or loading. The treatment increases surface wear resistance, decreases the coefficient of friction on the surfaces that are so treated, and increases the strength and modulus of elasticity. In certain types of materials, an increase in the surface concentration of such alloying metals such as wolfram, molybdenum, and tungsten, as well as oxygen and carbon is achieved. The structure comprises a coil and a controlled source of electrical power that generates a magnetic field for achieving the desired results.
