Structural changes in Ti1-xAlxN coatings during turning: A XANES and EXAFS study of worn tools
نویسندگان
چکیده
Structural changes in Ti1-xAlxN coated tool inserts used for turning 316L stainless steel were investigated by XANES, EXAFS, EDS, and STEM. For coarse-grained fcc-structured coatings, with 0 ≤ x 0.62, the XANES spectrum Al-content. Ti 1s line-scans across rake face of worn samples reveals that TiN-enriched domains have formed during Ti0.47Al0.53N Ti0.38Al0.62N as a result spinodal decomposition. The spectra reveal locations on which most TiN-rich formed, indicating part tool-chip contact area experienced highest temperature turning. Changes pre-edge features structural occur also w-TiAlN phase fine-grained EDS shows Cr Fe from adhere to machining. show is oxidized end length while adhered retains same fcc-structure steel.
