摘要：

Methods have been developed to determine the elasticity modulus E of coatings by the use of diagrams of pyramidal indenter penetration. The elasticity modulus was measured for diamond-like carbon (DLC) films produced by vacuum arc deposition of carbon plasma fluxes, separated from macroparticles and neutral atoms, onto copper substrates. It is shown that high density (rho = 3.4 g cm-3) DLC films have Young's modulus E = 900 +/- 10 GPa. When the experimental accuracy is taken into account, this value is almost coincident with Young's modulus for diamond. As the density decreases to 2.4 g cm-3, the E value decreases to 500-600 GPa, corresponding to a value intermediate between Young's moduli for diamond and graphite.
