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.
