Abstract
In this study uncertainties of measurement are evaluated for residual stresses in coatings
determined by the method of measurement of the longitudinal deformation of a tubular substrate, a
wire substrate and a strip substrate. Higher uncertainty was observed in the case of applying a thin
coating on a strip substrate. The precision of the equipment depends on the elastic element used for
measurement of the longitudinal deformation of the substrate. Residual stresses were determined in
the galvanic nickel coating deposited on a tubular substrate, a wire substrate and a strip substrate
from the Watts bath. Copper and brass was used as the material of the substrate. The investigated
experimental system is presented.
