TiBN hard films were coated on the surface of disks (SKD11) by a physical vapor deposition (FVD), and the coefficients of friction were measured by a SRV test machine at room and high temperatures (100,200,300,400℃) in dry condition. Then, the coating surfaces were observed using a microscope. The coefficients of friction of the coated disks were lower than those of disks without coating at all temperatures. The coefficients of friction of disks coated the TiBN films became lower at 300℃. At 400℃, the coefficient of friction of TiBN coating with (111) preferred grain orientation was the lowest In addition, it was observed that the wear tacks on the olsk surface with TiBN(111) coating and the counter material were the smallest at higher temperatures.
