Cutting Tool Materials

The design concept of functionally graded materials was first introduced into the development of self-lubricating ceramic cutting tool materials. An Al2O3/TiC/CaF2graded self-lubricating ceramic cutting tool material was designed and fabricated. Mechanical properties were evaluated by comparing with those of Al2O3/TiC/CaF2homogeneous self-lubricating ceramic cutting tool material. The results showed that the Al2O3/TiC/CaF2graded self-lubricating ceramic cutting tool material had superior performance to the counterpart. Graded self-lubricating ceramic cutting tool materials are bound to have promising prospect in the field of high speed dry machining.

Cutting Tool Materials

In this paper, the effects of addition of solid lubricants on mechanical properties, tribological properties and cutting performance of ceramic cutting tool materials were analyzed. The problem that existing homogeneous self-lubricating ceramic cutting tool materials were not available to possess rational combination of antifriction and antiwear properties was pointed out. The main methods to acquire graded self-lubricating materials were discussed. The design concept and research prospect of graded self-lubricating ceramic cutting tool materials were proposed, which would have promising applications in the field of high speed cutting.

Cutting Tool Materials

This paper analyzes the reasons of the defects generation of the ceramic cutting tool materials. The defects in the ceramic cutting tool materials are caused by chemical compatibility and physical mismatch during the designing process, and caused by grain abnormal growth and sintering parameters during the preparation stage. The database of low defect ceramic cutting tool is established and the data structure of the database is described. The users can use the database to design the tool material system through the mode that can reduce the defects.

Cutting Tool Materials

Al2O3/TiC ceramic tool materials with the addition of solid lubricants such as BN and CaF2 were produced by hot pressing. Effect of the solid lubricants on the microstructure and mechanical properties has been studied. Results showed that AlN phase resulted from the reaction of Al2O3 with BN was formed in Al2O3/TiC/BN composite after sintering. Significant micro-cracks resulted from the residual stress owing to the difference in the thermal expansion coefficient were found on the polished surface, and caused large mechanical properties degradation. While Al2O3/TiC/CaF2 composite showed higher flexural strength, fracture toughness, and hardness compared with that of Al2O3/TiC/BN composite owing its porosity absent and finer microstructure.
