Effect of Nano-scale TiN on the Mechanical Properties and Microstructure of Si3N4 Based Ceramic Tool Materials B.
Moreover the mechanical properties of the materials can be kept reliable at the high temperature of above 10000.
Results and Discussion The mechanical properties of Si3N4 ceramic tool materials and Si3N4/TiN nanocomposites tool materials are illustrated as a function of temperature at the holding time of 40min and pressure of 30MPa in Fig.1.
The hardness of both materials increase greatly with the temperature, furthermore the hardness of Si3N4/TiN nanocomposite tool materials is improved remarkably after the temperature exceeds 1700�.

For these reason, the TiNi alloy is currently highlighted for medical stent material better than other materials.
EP is load free machining so it is suitable for the polishing of both complex shapes and hardened materials, which are difficult to machine mechanically, because in EP the electrode and the workpiece are not in contact with each other.
