  • THERMALLY MODIFIED OXIDE BASED PRETREATMENTS FOR METALS AND METHODS OF MAKING THE SAME
    Publication number: 20230243060
    Abstract: Provided herein are corrosion resistant metal substrates and methods for producing the same by thermal modification. The disclosure provides methods for producing corrosion resistant substrates by producing a pretreatment film on a surface of a metal substrate and heating the pretreated metal substrate. In particular, the metal substrate and/or the pretreated metal substrate of these methods is in an F temper, a T4 temper, or a T6 temper.

  • Driveshaft system
    Publication number: 20070072688
    Abstract: The present invention provides a dampening system including a driveline including a tubular driveshaft; and at least one attenuator positioned at frequency nodes within the tubular driveshaft, the attenuator including a dampening material disposed about a perimeter of a rigid carrier corresponding to an interior surface of the tubular driveshaft, the rigid carrier uniformly distributing the high frequency dampening material about the interior surface of the tubular driveshaft. The present invention also provides a method for uniformly distributing an expandable material about the interior surface of a tubular driveshaft.
