  • Publication number: 20220048243
    Abstract: A method for performing sub-surface porosity detection in an additively manufactured part. The method includes providing, by a laser radiation source, a first radiation to a region of a powder bed along a beam of the first radiation, the region of the powder bed being part of a corresponding region of an additively manufactured part. Infrared imaging of the region of the powder bed is performed while the first radiation is being provided to the powder bed. A processor generates data sets indicative of the temperature of the region of the powder bed; and the processor further detects, from the data sets, a defect signature indicative of the formation and/or presence of a sub-surface defect in the region of the additively manufactured part.

  • Patent number: 10876200
    Abstract: A hydrogenated diamond-like coating (“H-DLC”) for metallic substrates provides improved reliability. The H-DLC is relatively soft and elastic. Unlike hard and/or inelastic coatings in the prior art, the present coatings do not exhibit a loss of adhesion (delamination). A bonding layer may be used between the metallic substrate and the H-DLC. H-DLC coatings can, for example, be used in bearings and gears to reduce the occurrence of micropits and, ultimately, product failure.

  • Publication number: 20200239802
    Abstract: The presently disclosed technology relates to a nano-additives to improve the performance of lubricants, oils, and greases. More specifically, the presently disclosed technology relates to applying capped metal oxide nanoparticles, such as capped zirconia nanoparticles, in the lubricants to produce a tribofilms on the lubricating surfaces to provide wear protection to the said surfaces. Also, the interaction of the capped zirconia nanoparticles with other commonly used additives in lubricants may further optimize the performance of the resulting tribofilms.

  • Patent number: 9926622
    Abstract: A method for making a pitting resistant carbon coating that includes a hydrogenated diamond-like coating (“H-DLC”). The H-DLC is relatively soft and elastic. Unlike hard and/or inelastic coatings in the prior art, the present coatings do not exhibit a loss of adhesion (delamination). A bonding layer may be deposited on a metallic substrate and the deposited H-DLC on the bonding layer.
