Abstract

A peculiar relief generally appears on the sample surface while testing wear resistance, which impairs the results of texture analysis by X-ray diffraction methods. The main reason for this is screening influence of the surface roughness on the X-ray passing through. From model representations, the influence on the screening of the relief parameters and the characteristic angle of reflection of X-rays is shown. Distribution of the parameters of a relief that actually forms is analyzed. A computer-assisted method of calculation of pole figures that excludes the screening effect is suggested. As an example of the method of application, the results of the analysis of textures that form upon testing wear resistance under condition of dry friction by slipping in pairs of samples of the β-titanium alloy VT35 doped with hydrogen are presented.
