  • Patent number: 11155905
    Abstract: Improved steel compositions and methods of making the same are provided. The present disclosure provides advantageous wear resistant steel. More particularly, the present disclosure provides high manganese (Mn) steel having enhanced wear resistance, and methods for fabricating high manganese steel compositions having enhanced wear resistance. The advantageous steel compositions/components of the present disclosure improve one or more of the following properties: wear resistance, ductility, crack resistance, erosion resistance, fatigue life, surface hardness, stress corrosion resistance, fatigue resistance, and/or environmental cracking resistance. In general, the present disclosure provides high manganese steels tailored to resist wear and/or erosion.

  • Publication number: 20140173995
    Abstract: Provided are methods to make a drilling tool with low friction coatings to reduce balling and friction. In one form, the method includes providing one or more drilling tool components with specified locations for fitting cutters, inserts, bearings, rollers, additional non-coated components, or combinations thereof; cleaning the one or more drilling tool components; applying masking for fitting cutters, inserts, bearings, rollers, additional non-coated components or combinations thereof; applying a multi-layer low friction coating to the cleaned specified locations; removing the masking from the cleaned and coated specified locations of the one or more drilling components; inserting cutters and inserts and assembling moving parts to the cleaned and coated specified locations of the one or more drilling tool components; and assembling the one or more drilling tool components to form a drilling tool.
