Patent number: 9377287Abstract: A method of configuring an eddy current detector to measure a thickness of a coating on a substrate includes measuring an impedance of the coated substrate, and establishing an impedance plane plot using a computer. The method may also include determining a rotation angle. The rotation angle may be an angle of rotation of the impedance plane plot that will make the inductive reactance component of the impedance substantially insensitive to substrate electrical conductivity within a coating thickness range. The method may further include establishing a calibration curve that is substantially insensitive to substrate electrical conductivity using the rotation angle. The calibration curve may be a curve that relates the inductive reactance component of the impedance to coating thickness.Type: GrantFiled: November 17, 2011Date of Patent: June 28, 2016Assignee: Caterpillar Inc.Inventors: Yong Tian, Douglas Alexander Rebinsky, Christopher Anthony Kinney, Kegan Luick

Publication number: 20160169056Abstract: A process for repairing a section of a rotatable shaft is disclosed. The section of the rotatable shaft has a surface portion having a surface parallel to an axis of rotation of the rotatable shaft and axial ends perpendicular to the axis of rotation of the rotatable shaft. The process includes preparing a well region extending over a perimeter of the section and extending downward in the surface portion, depositing material into the well region to fill the well region using a welding process and displacing a portion of the material that was deposited in the well region. The well region has a bottom portion that is substantially parallel to the axis of rotation and includes opposing sidewalls. Each sidewall extends proximate to the axial ends of the rotatable shaft and directly adjoins a remaining portion of the surface portion.Type: ApplicationFiled: December 10, 2014Publication date: June 16, 2016Applicant: Caterpillar Inc.Inventors: Kegan Luick, Jeffery Stark, Larry Bright, Daniel Cavanaugh, Eric Jeffery
