Reducing Fracture Tendencies in PCBN FSW Tools

2009
Abstract : The overall goal of this program is to increase the life of PCBN tools in friction-stir welding of high temperature metals. This will be achieved through the following objectives: (1) Understand the fundamental causes for limited lifetimes of PCBN tools during Friction-Stir Welding (FSW) of high temperature metals, including both wear and ...

Machinability of Abrasion Resistance Cast Iron with PCBN Cutting Tools

Materials and Manufacturing Processes, 2008
Highly abrasion and erosive resistance materials are an important group of materials and has very wide applications in many industrial areas. The characteristic properties for this material include the castability and the superior wear resistance. The material, however, is in the group of hard-to-machine materials due to its abrasion to cutting tool ...

To the Question of the Mechanism of the Effect of Coating on the Durability of Tools from PCBN

2020
The paper discusses the results of the tool-life tests of PCBN cutting tool with PVD coating and the mechanism which could be accounted for declining of its wear rate. The results of research showed that in condition of finishing of hardened steel (52–54 HRC), PCBN with (TiAlSiY)N/CrN PVD coating demonstrated significantly lower wear rate parameter in ...
