  • Ti—Si—C—N piston ring coatings
    Patent number: 10316970
    Abstract: A Ti—Si—C—N coating for a piston ring and a method forming such coating, wherein the deposited coating exhibits a thickness in the range of 10.0 micrometers to 20.0 micrometers and exhibits a coefficient of friction of less than 0.15 and a wear rate of less than 10×10?6 mm3/N/m. The coefficient of friction being measured on a Plint TE77 and the wear rate being measured against an alumina ball of 0.25 inches in diameter at a load of 1 N at 100 rpm in a dry environment. The deposited Ti—Si—C—N coating includes nanocrystalline phases in an amorphous matrix.
    Type: Grant
    Filed: November 22, 2016
    Date of Patent: June 11, 2019
    Assignee: Southwest Research Institute
    Inventors: Jianliang Lin, Ronghua Wei, Peter Mark Lee, Daniel Christopher Bitsis, Jr.
