    The article reports on the dependency of friction and wear of a-(Ti,C,N) films on the nitrogen content. The amount of nitrogen N in the film was controlled by partial pressure of nitrogen p(N2) in the Ar + N(2) sputtering gas mixture. It is shown that the incorporation of N in the film results in the increase of (i) the coefficient of friction mu (increases from 0.12 to 0.37), (ii) the coefficient of wear k (increases from 0.16 x 10(-6) to 0.93 x 10(-6) mm(3)/N m) and the decrease of (i) the film hardness H, (ii) effective Young's modulus E*, (iii) the elastic recovery W(e) of film and (iv) the ratio H/E*. The changes of mu and k of the a-(Ti,C,N) film correlate well with changes of the film mechanical properties (H and E*) and its mechanical behavior (W(e), H/E* and the ratio H(3)/E*(2)) characterizing the film resistance to plastic deformation
