Optimization of Crystalline Diamond Coating Structure Architecture for Improving Adhesion and Cutting Performance in Milling with Cemented Carbide Inserts

The adhesion, structure architecture, and residual stresses of crystalline diamond coatings (CDCs) on cemented carbide inserts are the factors that significantly affect tool life. influence these cutting performance cannot be investigated separately since interactions among them exist. paper elucidates such dependencies to optimize CDC architecture improve performance. In this context, possessing different architectures were deposited tools. fatigue endurance milling coated tools using impact tests, respectively. in film structures determined through tests appropriate (Finite Element Analysis) FEA evaluation corresponding results. According obtained results, application a bottom micro-structured prior deposition an upper nanolayered one with inferior thickness improves tools’ An optimum coating is associated ratio between bonding CDCs 2/1. Hereupon, augmentation life via compensates for high cost productivity. latter further enhanced as number replacements decreases.
