Regression Analysis of Nano and Macrotribological Properties of Diamond-Like Carbon Films Deposited Through a Filtered Cathodic Vacuum Arc Ion-Plating Method | Chapter 3 | Advances and Challenges in Science and Technology Vol. 6

 Diamond-like element (DLC) films have been extensively used in industries on account of their excellent characteristics in the way that high severity. In particular, there is a growing demand for their use as guarding films for mechanical parts on account of their excellent wear resistance and reduced friction cooperative. DLC films have been deposited by miscellaneous methods and many be dissimilar the DLC regions present in the ternary drawings proposed for sp3 covalent element, sp2 covalent carbon, and hydrogen.  Bend filtered photoelectric vacuum curve (FCVA) approach with dc and pulsed bias heat is used to produce diamond-like element (DLC) films. Atomic force microscopy was used to assess how changeful the bias voltage damaged the characteristics of nanoindentation and nanowear. The hardest DLC films had an average hardness of 50 GPa, a depressed dissipation modulus, a depressed elastic modulus to nanoindentation hardness percentage, and a strong nanowear opposition when they were deposited with a dc bias strength of 50 V. Nanoindentation hardness was definitely correlated with the Raman peak percentage Id/Ig, whereas wear wisdom was negatively correlated at this moment ratio. These nanotribological features highly depend on the films’ nanostructures. The tribological possessions of the FCVA-DLC films were also examined using a ball-on-disc test. The average friction cooperative of DLC films deposited with dc bias heat was lower than that of DLC films located with pulse bias service. The friction cooperative calculated from the ball-on-plate test was correlated accompanying the nanoindentation hardness in dry conditions. However, under horizon lubrication environments, the friction coefficient and particular wear rate had little correlation accompanying nanoindentation hardness, and wear behavior appeared to be affected by other factors to a degree adhesion substance between the film and substrate.
