Abstract

The main task of the present paper is the investigation of special cutting tool-steel, coated with TiC and TiN compounds. The tools were tested in different states by soft X-ray emission spectroscopy (SXES) in the regions of the CKα NKα FeLa and OKa emission peaks of the compounds, and they were investigated at different depths of the coating layer. The emission lines of the steel holder and its surroundings appear at depths of more than 600 nm. Shifts of the OKa peak and the fine structure changes in it show clearly the corrosion steps and states of the used tools, corresponding to the degree of use. The measurements prove clearly that heat treatment is a sensitive step in the technology of preparation of the CVD coated tool-steel. Exposure to oxygen during heat treatment decreases the life of the tool drastically.
