DLC

The coating by which taigyouchakusei has a high friction coefficient low

By utilizing plasma energy of PVD method , DLC film is formed by resolving hidro-carbon gas. DLC coating whose characteristics features very hard but thin film consists of Carbon atom as Diamond dose .

  • Features

  • Excellent hardness, Hv = from 3000 to 5000

  • Low treatment temperature (200°C or less), virtually eliminating thermal deformation

  • Very smooth surface and the lowest coefficient of friction

  • Low adhesion to the material used in powder compress molding

  • High adhere resistance for soft metals

  • Typical Applications

  • Many kinds of powder molds

  • Parts for semiconductor manufacturing

  • Molds and cutting tools for Aluminum , Copper and Brass

  • Parts requiring adhere resistance

  • Medical equipment such as stents

Application coating films with strengthened characteristics by changing composition of DLC
