Performance Evaluation of Cryogenically Treated Tungsten Carbide Insert on Face Milling of Grey Cast Iron

Abstract:

The objective of this study is to evaluate the wear progression of cryogenically treated and untreated tungsten carbide inserts during face milling of Grey Cast Iron which is a commonly used material in machine tool beds and automotive components due to low cost, high vibration damping capability, and easiness of manufacturing. Commercially available uncoated Tungsten Carbide insert with around 6% Cobalt (Co) content were selected for the study and flank wear and nose wear were taken as the performance evaluation criteria. The results show that the cryogenically treated samples have better wear resistance than the untreated inserts which could be ascribed to the martensitic phase transformation of Co from α-Co (FCC) to ε-Co (HCP) during the cryogenic treatment.
