CARBOZEN DLC(Diamond-Like Carbon) COATING
‘Diamond-Like-Carbon’ (DLC) is coating technology by which carbon (the main component of diamond) plasma is coated on substrate in a high vacuum. At this time, the coating layer appears as an amorphous structure and has a high level of hardness, low friction and wear-resistance. It is customized coating to improve the durability of products.
Characteristics of CARBOZEN ™ DLC
• High level of surface hardness : 1,500 ~ 6,000 Hv ▶ Improves the surface wear of products as a wear-resistant coating
• Low friction coefficient : 0.01 ~ 0.2 ▶ Improves fusion problem on mold surface as a solid lubrication coating
• Chemically stability ▶ Corrosion resistant and anti-sticky improving
• Carbon coating of amorphous : Ra ~ 0.3㎛ ▶ Superior surface roughness, possible to apply as mirror coating
• Low temperature coating :< 70℃▶Non thermal deformation of substrate
Coating solution of excellent durability with high hardness,low friction and wear-resistant properties
G-DLC coating technology can be applied in various fields such as molds, injection molds, cutting tools, electronics and vehicle parts. It will reduce cost and improves productivity and quality by extending the lifespan of tools.
Characteristics of G-DLC
• Improved corrosion resistance ▶ 00% corrosion prevention after coating
• Elevation of productivity ▶ Saves maintenance and repair time after coating
• Quality improvement ▶ Eliminates defective elements by lower usage of release agent
• Lifespan extension ▶ Maximum of X2.5 lifespan extension
Specialized in super-low frictional coationg solution
S-DLC is a coating technology which maximizes the low-friction property of DLCand able to down friction coefficient to 0.05.
If you apply to vehicle parts, you can see an improvement effect of fuel efficiency more than 5%. Also,improvement of quality and lifespan are expected.
Customized carbon coating solution possible to control electrical resistance
Through control of electronic resistance from ~10-3 ~ 1010 Ω/cm2, σ-DLC
is a customized coating service for electrical resistance control part such as;
the semi-conductor inspection equipment Prove, metallic bipolar plates for
PEMFC, and bio sensor.
• For mass production and reasonable price: coating thickness ‹ 100 nm
• Higher conductibility and corrosion resistance than rare metal
Customized coating solution adjusts friction as purpose
This is an innovative coating solutionwhich controlsfriction depending on the environment and intended usage within 0.2 to 0.5 offrictional coefficient.
It is applied to unusual environment like; controllingelectronicmodule parts, increasing vehicle windshield wiper functionality and etc.
Zero-defect coating solution without any drop-let nor pin hole
No pin hole nor drop-let on the product surface prevents breakage of the mold, improves releasing property and decreases fusion of articles and mold.
Plane DLC extends lifespan and improves quality of parts when applied to products such as specular components light guide plates, CD mold or Coin Head of the display industry.
Effectivecoating solution for compress or parts by improving inner pipe diameter's anti-abrasion and anti-corrosion
This is coating technology which uses HCD(HollowCathodeDischarge) and apply to the inner side of products which hasn't applied previous.
Application of Inner-DLC
• Compressor of appliances: Improvement of more than15% energy efficiency by improving durability
• Chemical plant pipe:Reduces the cost of maintenance by improving wear and corrosion resistance
This is a 0% hydrogen DLC high hardness coating solution which consists of 99.9% pure carbon with comlpetely controlled macro-particles
High-hardness thin film of 3,000 ~ 6,000 Hv with perfectly controlled macro-particles is completed by J&L TECH's magnetic filter and arc discharge of the CARBOZEN FA SYSTEM.
• Possible to have an ultra-smooth surface through dual bent filtering
• High adhesion to substrate
• Easy maintenance and high reproducibility
Application of ta-C
▶ Micro drills, end mills, cutting tools and engine component parts
▶ Machining tools of nonferrous metals like Al, Cu, and the tools for implantation
▶ Mproving the roughness of surfaces by preventing the fusion of tools and nonferrous metals
▶ Prevention of blade damage
▶ Heat suppression during process by reducing frictional heat
▶ Lifespan extension more than 5 times for tools
▶ Solid lubricating function when applied to engine component parts
Coating solution for improving fluidity and anti-stick of resins.
MIRAGE ™ COATING is a coating service which improves the lifespan and durability of product such as gravure roll, plastic injection mold, slot die nozzle and etc. It is a new trouble shooter to resolve the matter of stick and rise the liquidity of various resins
Ensures an outstanding anti-sticky at the same time improves the durability and mechanical properties of the
product.
• Increases the contact angle of the liquid after MIRAGE COATING
• Adjust hardness and thickness of coating which is customizable depending on the use of the product
• Improves hardness more than 10times and rises anti-sticky compared to existing nickel-plating
