CVD- Diamond Coating Application（TAC/DLC）
Product detail
Diamond-like carbon coated cutting tools
Material development of the element carbon in diamonds (different arrangements of atoms)
What is diamond-like carbon? (Amorphous carbon coatings containing more than 50% tetrahedral structure)
Soft enough to be used as a lubricant（the left）The hardest material in nature（the right）
Diamond-like carbon (DLC) coating
Technical principle: Combining arc ion plating and plasma-assisted chemical deposition technology, the target material
and process gas are ionized through arc ion plating technology first, and a Cr transition layer is deposited onto the
workpiece under bias acceleration to improve the film base bonding force, and then through plasma-assisted
chemical vapor-phase technology, the hydrogen-containing compounds are passed through to carry
out a glow discharge, and a DLC lubrication layer is deposited onto the workpiece under bias acceleration.
DLC and TAC performance distinction, micro-drilling coating TAC will be better than HLDLC

Diamond-like carbon coating tools
Uses: Enhance the wear-resisting and lubricating properties of the blade, molding and drilling of various
ordinary plates and environmental protection plates, especially suitable for high quality requirements of
the edge of the plate and high requirements of the hole roughness;
Advantages：It can strengthen the dust removal ability of micro cutting tools, and improve the life
of micro tools with very small diameter and large length-to-diameter ratio more obviously, with high
dimensional accuracy, high life, and excellent board edge quality.
Application Areas
DLC coated series tools are widely used in FPC flexible boards, package substrates, pure aluminum and
aluminum alloys, pure copper and copper alloys, etc. They can also be used in common single/double
sided boards, 5G communication boards, high speed boards, etc.
Application 1 DLC coated drill bit processing SEVER board
