    TiAlN coating was deposited on the surface of 20Cr steel samples by physical vapor deposition. TiAlN coated samples and 20Cr steel
    matrix samples were in three conditions of friction to do reciprocating friction and wear tests with a Si 3N4 ceramic ball friction pair
    which was loaded 2, 5 and 8 N The wear images and the distribution of elements were obtained by the scanning electron microscope
    and the energy spectrometer respectively. Then the three-dimensional profile meter was used to get the profile of the grinding marks
    and the step meter gained two-dimensional contour curve. Results of investigation showed that the friction coefficient of TiAlN waterbased
    lubrication friction increased with the increase of the load, and TiAlN oil-based lubrication friction had the same rule. Under
    5 and 8 N loads, the friction coefficients were higher than both ofTiAlN and 20Cr steel matrix dry friction in the middle friction stage.
    As concluded through the experimental analysis, abrasive wear was the main wear mechanism of dry friction; the fatigue wear and
    oxidation wear were accompanied in some conditions. Water had a great influence on the micro morphology of the grinding mark.
    The wear of 20Cr steel matrix is the most serious.
