Particle-free, hydrogen-free DLC coating (TAC)

Particle-free, hydrogen-free DLC coating (TAC)

Achieving high hardness, strong adhesion, and excellent wear resistance with room temperature film formation! By coating after removing impurities, it also contributes to improving fuel efficiency in automotive parts!

The hydrogen-free DLC film (ta-C) using the FCVA method differs from existing PVD and CVD methods by removing impurities through an electromagnetic filter, resulting in fewer particles, excellent adhesion, and high wear resistance. Additionally, since film formation is possible at room temperature, it can be applied to various materials such as low melting point materials like resins, ceramics, and rubber. Furthermore, thick films of over 10 micrometers can be created, enhancing the quality of automotive parts and increasing added value through longer lifespan. In addition to the DLC film, please also try the composite metal film "MiCC film," which excels in release properties during plastic molding. 【Features】 ■ Achieves high hardness, strong adhesion, and excellent wear resistance ■ Capable of creating thick films over 10 micrometers ■ Film formation possible at room temperature ■ Applicable to various materials *For more details, please download the PDF document or feel free to contact us.

DLC coating characterized by low friction and high hardness.

DLC coating characterized by low friction and high hardness.

Improves the lifespan of tools and parts with a thin film, high-hardness DLC coating.

We offer a lineup of "DLC" for molds and machine parts, and "DLC-i" for aluminum alloy cutting tools. DLC coating demonstrates an overwhelmingly low friction coefficient against metal materials, achieving a friction coefficient comparable to oil lubrication even in dry conditions. It improves release properties to suppress adhesion of soft metals (such as aluminum alloys). DLC-i coating features a thinner film and higher hardness than DLC coating, making it ideal for cutting aluminum alloys. 【Lineup】DLC, DLC-i *For more details, please refer to the PDF document or feel free to contact us.

[Improved Wear Resistance × Sliding Properties × Release Properties] Surface Treatment Technology DLC Coating

[Improved Wear Resistance × Sliding Properties × Release Properties] Surface Treatment Technology DLC Coating

By changing the film formation method, we achieve longer product life by controlling wettability and sliding properties! It can also accommodate large workpieces. We will explain about DLC!

DLC (Diamond Like Carbon) is a hard coating that lies between diamond and graphite. Its hardness is 1500 Hv, and the friction coefficient ranges from 0.1 to 0.2. It has heat resistance and can be used at temperatures up to about 200°C. Additionally, by changing the gas used, it is possible to control the wettability. 【Characteristics】 ■ Hardness: 1500 Hv ■ Friction coefficient: 0.1 to 0.2 ■ Chemical resistance: insoluble in acids and alkalis ■ Electrical resistance: insulating ■ Contact angle (for water): 58° ■ Film thickness: standard around 2 μm (up to a maximum of 10 μm) ■ Compatible size: can accommodate up to a diameter of 1000 mm, length of 3500 mm, and weight of 5.6 tons For more details about DLC or if you wish to request a prototype test, please refer to the PDF materials or feel free to contact us.

Hybrid DLC coating with WPC treatment

Hybrid DLC coating with WPC treatment

It is effective during non-lubricated conditions and boundary lubrication (when there is little oil and solid contact occurs)!

"DLC coating" is a coating technology that, despite being a thin film of approximately 1μm (1/1000mm), possesses various characteristics such as high hardness, wear resistance, low friction, and low adhesion. Our company has successfully developed a technology that combines DLC coating with WPC treatment. This forms a smooth oil reservoir, enhances wear resistance, and the hard coating further prolongs its effects. 【Features】 ■ Reduces friction ■ Suppresses oil temperature rise and degradation ■ Improves response and contributes to smooth operation ■ Increases wear resistance, leading to longer component lifespan ■ Maintains good vehicle condition, resulting in cost reduction *For more details, please download the PDF or feel free to contact us.

DLC Coating Complete Process

DLC Coating Complete Process

Inside the factory's secret grand reveal! Meticulously honed techniques create exquisite DLC coatings.

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 chamber, we inject acetylene gas. Various gases are injected, and high voltage is applied. 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.

DLC Coating <Features>

DLC Coating <Features>

Water-repellent, chemical-resistant, antibacterial, and more! A coating with various features.

The features of DLC coating are "a film thickness of a few microns," "a variety of hardness (1000 to 7000 Hv)," and "excellent sliding properties." It has various characteristics such as gas barrier properties (gas blocking), optical properties (infrared transmission and ultraviolet blocking), water repellency, chemical resistance, and antibacterial properties. Please feel free to contact us if you have any requests. 【Main Features】 ■ High hardness of 7000 Hv (AC-X) can be achieved by the way carbon is bonded ■ The entire structure is amorphous (like glass), providing excellent sliding and smoothness ■ Because it is primarily composed of carbon, it has excellent non-compatibility with non-ferrous metals, making it less likely to cause adhesion, welding, or seizing ■ Low hardness DLC tends to produce fewer scratches and wear on the opposing material during friction *For more details, please refer to the related links or feel free to contact us.
