of hard coatings in an already optimized tribo‐system in industrial conditions represent an interdisciplinary problem. For high efficiency, tribosystem must include as many as possible well controlled parameters. Today process technology and performance experiences offers indication that for the properly chosen hard coating, one can derive for a given tribo‐system some general rules. Our own development of hard coatings and experience with TiN coatings in more than 200 factories of various production is a basis of this work in which we analyse those parameters of each tribo‐system studied, that gave us sufficient statistics to derive first general rules in this field. For our analysis we use SEM, thin film X‐ray technique, AES depth profiling, Talysurf profiler, optical microscopy, STEM with EDAX and metallography. As tool materials we studied HSS, HSS‐Co, ASP and hard metals, while coating was only TiN. The following items were investigated: stoichiometry on various tool materials; topography of tool surface and coating on it; defects on original surfaces; microhardness on tools; quality of produced surfaces and optimization of tool life; productivity and reliability of TiN coated tools in industrial conditions. All these data were compiled to other references and used as basis to derive general rules.
