This paper describes evaluations of dynamic mechanical properties of typical metals (Al, Cu, Ti, Ni, Co, and Mo) with single pendulum scratch tests. The: curve fitting method with a polynomial has been used to calculate the geometrical parameters of the scratch track during the scratching process. The methodology and analytical modeling are developed for determining a series of mechanical properties, such as elastic modulus, shear modulus and cohesive strength of materials, with the help of calibrations to those of these metals. These parameters are effective to describe the dynamic mechanical properties of massive materials and modified surfaces of materials. Using these methods, the mechanical properties of plasma sprayed Ni-ZrO2 coatings are determined. (C) 1999 Elsevier Science Ltd. All rights reserved.
