Abstract: The TiN coatings were deposited onto the low carbon steel
substrates with different temperatures (150, 250, 350 and 450
℃), using hollow cathode discharge (HCD) ion plating method. The
measurements of the microhardness and wear resistance of the
coatings show that the hardness value slowly increases and the
wear resistance remains almost unchanged with increasing the
substrate temperature from 150℃ to 450℃. The reason for effect
of the substrate temperature on the properties and morphologies
of the coatings was investigated by means of X-ray diffraction
and scanning electron microscope (SEM).
