Determination of dynamic mechanical properties of metals from single pendulum scratch tests

This paper describes evaluations of dynamic mechanical properties of typica l metals (Al, Cu, Ti, Ni, Co, and Mo) with single pendulum scratch tests. T he: curve fitting method with a polynomial has been used to calculate the g eometrical parameters of the scratch track during the scratching process. T he methodology and analytical modeling are developed for determining a seri es of mechanical properties, such as elastic modulus, shear modulus and coh esive strength of materials, with the help of calibrations to those of thes e 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.
