“…A linear variation between the square of the change in resonant frequency shift (Δf r ) 2 of the cantilever-tip probe with vertical displacement (z) is equal to the parameter α 2 . It is well demonstrated (Useinov, 2004;Gogolinski et al, 2004) that α is directly proportional to E* through a power-law relationship, i.e. α equals (E*) n where n ≈ ½.…”

Copper-Nickel-Carbon nanocomposite coatings are synthesized by the sequential sputter deposition of carbon (C) and a copper-nickel (Cu 1-x Ni x ) alloy. A distinct transition occurs as the Ni content (x) is increased from 0 to 1.00 during the Cu 1-x Ni x alloy deposition. The coating morphology changes from a dispersion of metallic Cu-particles in a C matrix to a well-defined nanolaminate structure. Between these morphological forms, a new prototype nanocomposite is produced at a Ni concentration (x) of 0.1-0.4 with the appearance of an interpenetrating matrix structure of C and Cu(Ni). This morphological structure has both a high 24-27 GPa hardness (H) and a low elastic modulus (E) of 144-169 GPa that results in a record high values of H/E at 1/6 and a H 3 /E 2 at 0.67-0.69 GPa in a novel compliant and hard coating.

“…This generalized expression can accommodate the most basic form of a nonlinear relationship between * and , as is commonly found in experimental measurements. A two-term Taylor series expansion [24,25] for the solution of the Hertz-contact condition between tip and surface yields an exponent value of one, that is, a linear relationship. In the next section, the more satisfactory formulation of a generalized nonlinear relationship between * and will be seen to require additional terms in the Taylor series expansion.…”

“…The dynamic behavior of the indenter probe in contact with the surface is derived from the equation of motion and the equation for the frequency of oscillation of the system.

“…The oscillating bubble method [23] is another technique for measuring surface elasticity of liquids. The tapping mode elastic modulus measurement technique [24][25][26][27][28][29] provides another relatively new method for measuring the reduced elastic modulus. The measurement is based on the oscillation frequency of a probe that is in elastic contact with the surface.…”

Young's modulus of nanocrystalline metal coatings is measured using the oscillating, that is, tapping, mode of a cantilever with a diamond tip. The resonant frequency of the cantilever changes when the diamond tip comes in contact with a sample surface. A Hertz-contact-based model is further developed using higher-order terms in a Taylor series expansion to determine a relationship between the reduced elastic modulus and the shift in the resonant frequency of the cantilever during elastic contact between the diamond tip and sample surface. The tapping mode technique can be used to accurately determine Young's modulus that corresponds with the crystalline orientation of the sample surface as demonstrated for nanocrystalline nickel, vanadium, and tantalum coatings.
