An advanced technique for investigating the frictional property of materials depended on crystal preferred orientation is newly proposed. The crystal preferred orientation of ZnO coating films on stainless-steel substrates was markedly changed with the magnitude of an applied load, which was observed by X-ray diffraction analysis with micropoint focus X-ray optics. Also the dependence of the friction coefficient on the crystal preferred orientation was measured. Using the new method, it is possible to find the appropriate crystal preferred orientation for coatings with the desired value of the friction coefficient. Therefore, the technique is expected to be an effective method for tribology research.
