DLC coating machine (diamond-like carbon coating machine) is a special equipment used to deposit diamond-like carbon film on the surface of objects.

DLC film is an amorphous carbon material that combines the excellent properties of diamond (high hardness, high wear resistance, high insulation, high thermal conductivity) and graphite (low friction coefficient, self-lubricating property).

This coating technology is widely used in modern industry.

Features：

Excellent film performance

Ultra-high hardness (H):

Much higher than traditional coatings such as hard chrome and TiN.

Extremely low friction coefficient (μ):

Excellent self-lubrication, significantly reducing friction and wear.

Excellent wear resistance:

Significantly extends the service life of the workpiece, especially suitable for high wear conditions.

Good chemical inertness:

Acid and alkali corrosion resistance, oxidation resistance.

Good thermal stability:

Stable performance within a certain temperature range.

High resistivity/insulation:

Pure DLC is a good insulator.

Good biocompatibility:

Some types of DLC (especially hydrogen-free ta-C) are suitable for medical devices.

Smooth and dense surface:

Can reduce friction resistance and improve sealing

Process flexibility and diversity

Many adjustable parameters:

By changing the gas composition (such as adding Si, F, N, W, Ti, Cr and other elements), gas ratio, gas pressure, plasma power, bias, temperature and other parameters, DLC films with different properties (such as a-C:H, a-C, ta-C, Me-DLC, etc.) can be prepared to meet different application requirements (hardness, friction coefficient, bonding force, internal stress, color, conductivity, etc.).

Doping modification:

It is easy to achieve element doping to give DLC films special properties (such as improving bonding force, reducing internal stress, improving hydrophobicity, increasing conductivity, etc.).

Environmental friendly
Compared with traditional hard chrome electroplating processes, the DLC coating process does not emit highly toxic pollutants such as hexavalent chromium and is more environmentally friendly.

Wide adaptability of substrate

It can be deposited on a variety of substrates such as metals (steel, aluminum alloy, titanium alloy, copper, etc.), ceramics, cemented carbide, silicon wafers, plastics.

Low temperature deposition

Many DLC deposition processes can be performed below 200°C or even at room temperature, making them suitable for temperature-sensitive substrates (e.g. precision parts, plastics, tool steels with low tempering temperatures).

Good film uniformity

By optimizing the cavity design, turret motion, plasma distribution and process parameters, relatively uniform film layers can be obtained on workpieces with complex shapes (such as gears, piston rings, mold cavities).

Applications:

Automotive industry

Tools and dies

Precision machinery and parts

Medical devices and implants

Aerospace

DLC coating machine is a key equipment in the field of modern surface engineering.

It uses advanced plasma technology to impart a diamond-like carbon film layer to the surface of the substrate, thereby greatly improving the comprehensive performance of the workpiece, such as wear resistance, friction reduction, and corrosion resistance.

Its flexible process, excellent performance, environmental friendliness, and extremely wide range of applications make it play an indispensable role in high-tech industries such as automobiles, tools, medical treatment, electronics, and aerospace, and is an important technical means to improve product performance and life.
