Abstract:
A Ti(C,N)-based cermet grade for sawblade production was developed, targeting performance of commercially available grades. Firstly, laboratory investigations focused on commercial cermets compositions and properties. Subsequently, a variety of laboratory grades were prepared and characterised (HV10, KIC, LOM and SEM, HC, MS, CGHE, DTA, XRF). Some deeper analysis was done on individual grades and formulations (XRD, WDS-EPMA, EGA-MS). A set of such optimised cermet prototypes was prepared in the laboratory and brazed to sawblades. The results were used for further development of the grades, moving step-by-step to industrial upscaling into cermet production. After each step, cutting tests were performed to check the cutting performance in real conditions. Starting from almost 50% tool life of laboratory grades as compared to a commercial grade, systematic improvements enhanced the cutting performance of the grade developed in this study to outperform the commercial cermet target grade.
