Comparative Experimental Study of Tribo-Mechanical Performance of Low-Temperature PVD Based TiN Coated PRCL Systems for Diesel Engine

Figure 9

Wear rate as a function of TiN coating thickness: (a) cylinder liner wear rate when rings are TiN coated; (b) cylinder liner wear rate when rings are Cr coated; (c) wear rate of TiN coated piston rings; (d) wear rate of Cr coated piston rings. The error bars represent the standard deviation of the experiment.
