New Generation Of Surface Coating PCVD TechnoIogy & Equipment |
| Externally
hot DC pulse plasma chemical vapor deposition (PVCD) features simple equipment, low
deposition temperthee (<600ˇăC ), even coating thickness, high bond strength, multiple
coating materials varieties, and least deformation of workpiece. In particular prior to
the coating process, the ionitriding treatment is first conducted on the workpiece
surface, thus it can increase the bond strength between coating and matrix. By this
technology, the life service of the coated products can be raised by 2-6 times, some even
over 10 times. Meanwhile, low PCVD temperature will not produce any deformation on the
products nor reduce its hardness, so it is especially suitable for the surface treatment
of precision complicated cutting tools and dies. |
