Chikka processing "DS Hard"

Chikka processing "DS Hard"

Extremely minimal deformation and dimensional changes! Achieves a uniform processing layer even for shapes and deep holes.

"DS Hard" is a general term for the chika treatment conducted by our company aimed at improving product lifespan. The characteristics change depending on the type of gas, concentration, and treatment time, but typically, among the sulfide layer creation treatments, the "DS Hard-L" for wear-resistant parts, "DS Hard" for cutting tools, and "DS Hard-F" for hot forging molds are widely performed. [Overview] ■ Effective treatment dimensions: Φ600×1200 ■ Maximum weight: 500kg *For more details, please download the PDF or contact us.

Nitriding treatment

Nitriding treatment

It hardens a few micrometers from the surface. This is done after finishing, but the previous process is also important.

Plasma ion nitriding involves creating a glow discharge with the furnace body as the anode and the product as the cathode in a low-pressure nitrogen gas atmosphere, resulting in a soft light similar to a neon sign enveloping the product. The energy from the ions heats the product while simultaneously nitriding it. Our company has quickly adopted this plasma ion nitriding equipment to provide higher quality products. ● Extremely low distortion due to low-temperature processing ● High nitrogen potential allows for rapid formation of the nitrided layer ● By adjusting the gas ratio and temperature, the state of the nitrided layer can be controlled ● Good surface roughness due to processing in a vacuum ● Even materials like austenitic stainless steel can be nitrided uniformly

Micronite

Micronite

Wear protection for stainless steel! Even under external loads, the surface can easily adapt. *Can also comply with PFAS regulations.

Our developed "Micro-Night" is a new nitriding treatment that achieves both corrosion resistance and wear resistance, unlike conventional nitriding processes. By nitriding at a low temperature below 400°C, the formation of Cr oxides in the nitrided layer (S phase) is suppressed, making it easier to form a passive Cr film. The formation of the nitrided layer increases surface hardness by more than twice, narrowing the gap in hardness between the underlying stainless steel and the surface compared to coatings. 【Features】 ■ Achieves both corrosion resistance and wear resistance ■ Suppresses Cr oxides in the nitrided layer (S phase) ■ Facilitates the formation of a passive Cr film ■ Increases surface hardness by more than twice ■ The surface easily follows external loads *For more details, please download the PDF or feel free to contact us.

Strengthening Manual for Screws (Vol. 31) What other measures are there for preventing seizing?

Strengthening Manual for Screws (Vol. 31) What other measures are there for preventing seizing?

Introducing anti-seizing measures such as nitriding and shot peening!

To suppress the seizing of screws, treatments that enhance the surface properties of bolts and similar components, aside from applying lubricants, include heat-based surface treatments and physical processing, which are also effective. Now, let's take a look at what other methods are available. Nitriding, which uses nitrogen to harden the surface, involves infiltrating nitrogen (N) into the surface of steel to create iron nitride (FeN), a compound with iron (Fe). Depending on the type of nitriding, this iron nitride can be quite hard, resistant to wear, and has high sliding properties, making nitriding effective in suppressing screw seizing. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

Technical Introduction: "Nitriding Treatment"

Technical Introduction: "Nitriding Treatment"

It is possible to provide optimal nitriding characteristics for the required functions!

Nitriding is a treatment that generates hard nitrides such as those of Ar, Cr, Mo, Ti, and V by allowing nitrogen to diffuse into the material. As a result, it does not harden due to changes in the microstructure, leading to less distortion compared to carburizing. Additionally, the treatment temperature is between 500 and 550°C, making it an environmentally friendly process. Furthermore, with the integration and high precision of components, research and development of nitriding processes controlled by atmosphere is gaining attention as a heat treatment technology that minimizes distortion. However, in conventional gas nitriding processes, an excessive compound layer is formed on the surface, which can lead to peeling and dimensional changes. To address this issue, we have established a technology that utilizes H2 sensors to control the thickness of the compound layer through nitriding potential. ● For more details, please contact us.
