[Surface Treatment] JC Coat (Release Properties (Non-Stick), Water and Oil Repellency)

[Surface Treatment] JC Coat (Release Properties (Non-Stick), Water and Oil Repellency)

JC coat (high-performance DLC treatment) (release properties (non-stick), water and oil repellency, adhesion, dimensional accuracy)

■Excellent Characteristics 1) Due to the non-stick coating based on DLC, it excels in hardness, release properties, and water and oil repellency. 2) The adhesion is strong, and the risk of delamination spreading from defects in the film is low. 3) With a thin film of less than 1μm, the impact on dimensions is extremely small.

Surface treatment: DLC coating (wear resistance, release properties)

Surface treatment: DLC coating (wear resistance, release properties)

DLC coating (wear resistance, release properties)

■Outstanding Features The hardness is equivalent to Vickers hardness, with various properties of DLC available in the range of 1500 to 7000 HV. It excels in wear resistance due to its high hardness. Additionally, the coefficient of friction is as low as that of fluororesin, providing excellent release properties. It also has effects in preventing aluminum adhesion and gas barrier effects.

DLC coating

DLC coating

Prevents welding with excellent lubrication! Tribology coating suitable for tools, molds, and machine parts.

Our company offers 'DLC coating' that enables precise and smooth coatings, with excellent sliding properties, release properties, and resistance to adhesion. By adopting the UBMS (Unbalanced Magnetron Sputtering) method and forming a metallic gradient layer between the substrate and DLC, we achieve a highly adhesive film. This standard DLC film has a high reliability with a balanced friction, hardness, and adhesion. 【Overview】 ■ Color: Black ■ Film hardness: 26.4 GPa (Hv2,700) ■ Oxidation resistance temperature: 300℃ ■ Coefficient of friction: 0.2 ■ Processing temperature: Below 200℃ ■ Film thickness guideline: 1 to 1.5 μm *For more details, please download the PDF or feel free to contact us.

DLC for thin material cutting blades "Genius Coat HA"

DLC for thin material cutting blades "Genius Coat HA"

Excellent anti-welding properties! Hydrogen-free DLC with ultra-high hardness (>40 GPa) by PVD.

We would like to introduce our DLC "Genius Coat HA" for thin cutting blades. Thanks to its ultra-thin film specification (0.1μm), it can be coated without compromising the edge shape. It excels in anti-adhesion properties for soft metals like aluminum and is widely applicable as cutting tools and molds. Additionally, it can remove coatings from both carbide and steel, allowing for regrinding and recoating. Please feel free to contact us when you need assistance. 【Features】 ■ Ultra-high hardness (＞40GPa) hydrogen-free DLC by PVD ■ Excellent anti-adhesion properties for soft metals like aluminum, widely applicable as cutting tools and molds ■ Coating possible without compromising edge shape due to ultra-thin film specification (0.1μm) ■ Coating removal possible for both carbide and steel, allowing for regrinding and recoating *For more details, please download the PDF or feel free to contact us.

[Case Study] Surface treatment that combines "slipperiness" and "wear resistance"

[Case Study] Surface treatment that combines "slipperiness" and "wear resistance"

A case study that was able to reduce maintenance work for replacements due to high durability.

This is a case study from a company that manufactures soft packaging materials (packaging). They were experiencing issues with Teflon tape used on the transport guide of processing machines for transporting products, as it would stick to the products and required frequent replacement. Therefore, we proposed an additional DLC treatment after blast processing. This surface treatment, which excels in slip resistance and wear resistance, is very hard and has a low friction coefficient, allowing for smooth transport of the film and high durability, ensuring long-lasting slip performance. By applying DLC treatment on top of the blast processing, the film of the product was transported smoothly, and maintenance work for tape replacement was reduced due to its high durability. [Issues] - The friction coefficient was higher than that of the Teflon tape in use, causing friction resistance and preventing smooth transport. - Although we tried reducing the contact area with blast processing, it resulted in scratches on the product's film. *For more details, please refer to the PDF document or feel free to contact us.

DLC coating entire process

DLC coating entire process

Inside the factory's secret big reveal! Meticulously polished techniques create exquisite DLC films.

We would like to introduce the entire process of our DLC coating. First, we modify the substrate and perform thorough cleaning, carefully masking the unnecessary parts of the DLC film. After completely wiping down the waiting area in the chamber, we inject acetylene gas. Various gases are injected while applying high voltage. The film is built up by repeating the processes of film formation and cooling, taking about 6 hours to complete. 【Process】 1. Inspection and cleaning 2. Masking 3. DLC coating 4. Finishing *For more details, please download the PDF or feel free to contact us.

[Data] Extension of rolling fatigue life due to DLC coating

[Data] Extension of rolling fatigue life due to DLC coating

Examination of the changes in the metal structure of the surface layer of the metal substrate under DLC film formation!

This document is a research paper on the extension of rolling fatigue life due to DLC coating. The experimental methods are explained in sections including sample preparation, evaluation of film properties, fatigue testing, and evaluation of fatigue test samples, along with the experimental results, discussions, and conclusions. Currently, in the automotive parts sector, lightweight design and friction reduction aimed at improving fuel efficiency are urgent challenges, and the power transmission systems, including gears for transmissions, are also being targeted for miniaturization, weight reduction, and low friction.
