  • Publication number: 20140329081
    Abstract: Embodiments of the disclosed technology provide methods of boronizing titanium and other metals and metal alloys. The method proceeds, in an embodiment of the disclosed technology, by using a boron source, and placing it in a heated environment, followed by a reduced pressure environment, as is described in the disclosure. In a solid phase embodiment of the disclosure, boronized stainless steel alloys are produced having zero galling at 17,000 psi.

  • Publication number: 20060272434
    Abstract: A system and the method of use of the system for continuous deterioration rate measurements of sample materials are provided by the present invention. Mass loss is a versatile method for determining sample deterioration. Previous mass loss techniques employ determination at periodic intervals after removing the sample from the process environment thus providing non-continuous measurements, which affect accuracy and precision, increase analysis time, and are non-illustrative of actual working conditions. The disclosed invention suspends the sample, which is immersed in the process environment, from an electronic balance. The balance is connected to a computer for recording data on a predetermined time interval.
