Preface In recent years, hard and wear resistant coatings on materials have played a very important role in the metalworking industry. To perform a systematic study of the TiN-coated products of S6-5-2 (material number DIN1 · 3343) high speed steel and evaluate the coatings, it is necessary to conduct a detailed metallographic study. Although the system of dense metallographic sample
