WebIBC recommended coating the second forming segment with our Ceratough®-0601 Diamond Like Carbon (DLC) PVD coating. This DLC coating has an extremely low coefficient of friction and hardness much higher than the A2 steel. The customer tracked the tooling for 100 parts and then sent the die sections to IBC for analysis. WebBesides, the friction coefficient decreased with increasing sliding velocity and normal loads, due to the rolling effect of the physisorbed C60 molecules. The Langmuir-Blodgett (LB) technique15,16 and selfassembly method17-21 are known as the novel alternative approaches of preparing C60 films with good tribological properties.
