Plasma nitriding technology "Raster processing"

Plasma nitriding technology "Raster processing"

The nitrided surface has only a diffusion layer, resulting in a good surface finish and maintaining a glossy appearance!

"Raster processing" is a technology that forms only a tough diffusion layer without creating a compound layer. Since the process of polishing away the compound layer can be reduced, it contributes to cost savings. Additionally, by applying it to the substrate, the lifespan of molds and cutting tools can be extended several times compared to when only coating is applied, so we recommend composite hardening treatment using raster processing and PVD coating. [Features] ■ The nitrided surface consists only of a diffusion layer ■ The finished surface has good roughness and maintains gloss ■ Nitriding is possible in narrow slits and fine pores ■ Nitriding of cutting tools is possible ■ The release properties of resin molds are improved *For more details, please refer to the PDF document or feel free to contact us.

Nitriding Method "S.P.N. Method"

Nitriding Method "S.P.N. Method"

It can be safely applied to mirror-finished products and textured surfaces with minimal skin irritation from processing.

The "S.P.N. method" is a nitriding process for steel that utilizes plasma energy, differing from the conventional ion nitriding method that uses traditional plasma power. It causes less roughness on the surface of the treated material and can suppress the formation of compound layers, which are considered a drawback in the case of alloy steel. Therefore, it features reduced "dimensional changes" and "brittleness" compared to conventional methods. [Features] ■ Nitriding is possible for almost all types of steel, including stainless steel. ■ Stable glow can be maintained even for slit processed products, resulting in less variation. ■ Welding corrections can be performed directly after treatment. ■ By applying it to cutting tools and dies, and using it as a pretreatment for hard coatings such as PVD and DLC, greater effects can be achieved. *For more details, please download the PDF or contact us.

Technical book distribution now! Technical book "What is Nitride?"

What is nitriding treatment? A technical book explaining the characteristics of nitriding and gas nitriding treatments, including the relationship between processing time, processing temperature, and hardness.

Nitriding treatment is a chemical surface hardening method of surface hardening heat treatment, which combines with various metal elements to form hard nitrides that harden the surface. The purpose of nitriding treatment is to improve wear resistance, fatigue resistance, corrosion resistance, and heat resistance. The most popular special steel that is easy to nitridize is SACM645 (commonly known as nitriding steel), which contains Al, Cr, and Mo. Other suitable materials for nitriding include chromium-molybdenum steel, nickel-chromium-molybdenum steel, and stainless steel.

Nitriding treatment ≪Tuftride, QPQ≫

Nitriding treatment ≪Tuftride, QPQ≫

The classic salt bath soft nitriding treatment, Tuftride, and QPQ treatment are revived here. Significantly improves the sliding characteristics and corrosion resistance of machine parts. Complies with REACH regulations.

1. What is nitriding treatment: Nitriding is a process that involves permeating nitrogen ions into the surface of materials such as steel and titanium alloys to harden them. By allowing nitrogen ions to penetrate the metal, nitrides of the added elements in the base material (Cr, Al, Mo) are formed (CrN, AlN, Mo2N), creating a hard compound layer. The hardness of this compound layer depends on the amount of these additives, exceeding Hv1200 in alloy steels. There are methods that utilize salt baths, gas atmospheres, or ion environments. 2. Characteristics of salt bath soft nitriding treatment: - Unlike carburizing and high-frequency quenching, there is minimal deformation after treatment, eliminating the need for subsequent polishing. - There is no reduction in fatigue strength after treatment, as seen with hard Cr plating or zinc plating. Nitriding treatment not only improves resistance to galling, wear, and corrosion but also enhances fatigue strength. - In gas and ion nitriding, for complex-shaped parts, gases and ions may not circulate uniformly along the part's shape, leading to uneven nitriding. In a salt bath, abundant nitriding ions circulate uniformly over the entire surface of the part, forming a consistent nitriding layer. A dense and tough nitrided compound (ε-iron nitride) layer improves sliding properties. A porous layer of a few micrometers at the very surface retains lubricating oil, ensuring favorable sliding conditions. 3. Characteristics of Tuftride and QPQ: - Compliant with REACH regulations, zero use of toxic substances, and zero wastewater (all solid waste).

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.
