Please consider the thermal spraying method, which allows for flexible responses regardless of the base material's properties, shape, or coating thickness! The thermal spraying methods for surface modification include plasma spraying, explosion spraying, flame spraying, and arc spraying, with coating materials such as metals, alloys, ceramics, glass, and polymers. The purposes vary, including surface hardening, heat resistance, wear resistance, and the addition of special functions. [For more details, please download the catalog or feel free to contact us.]

Alumina (aluminum oxide) is an oxide of aluminum. Abradable spraying is a thermal spraying process conducted to obtain a coating with a property that allows it to be easily abraded. An example of its application is spraying onto the inner wall of a case opposing the turbine rotor to optimize the gap between the rotor and the case. Abrasive wear is a form of wear primarily caused by the cutting action of hard particles interposed between the uneven surfaces in contact. Electric arc spraying is a thermal spraying method that generates an arc between two linear metal spraying materials, and the metal droplets produced by the heat are atomized and accelerated by a jet of compressed air to be sprayed onto the substrate to form a coating. Yttria (yttrium oxide) is an oxide of yttrium. For more details, please download the catalog.

Thermal spraying involves feeding powdered spray material into an oxygen-acetylene flame, where it is heated while being injected into the flow of the combustion flame. Its low melting temperature and slow injection speed create unique advantages. For more details, please download the catalog.

The materials that NCI can spray are not limited to ceramics. For example, self-fluxing alloys. These are nickel or cobalt-based alloys containing more than 1.5% boron and silicon, which are remelted in an atmosphere of about 1100°C after being sprayed to form an alloy layer, creating a dense coating that adheres to the base material. They are characterized by excellent wear resistance. For more details, please download the catalog.

Rokaido thermal spraying is a method that uses an oxygen-acetylene flame as a melting heat source and utilizes rod-shaped sintered thermal spray materials. The melting temperature is approximately 3000°C. Only fully melted particles are accelerated and injected using an air jet flow. The equipment offers high flexibility, allowing for thermal spraying on complex-shaped substrates at pinpoint locations. For more details, please download the catalog.

Rod-type thermal spray materials are used for localized thermal spraying. Since only fully melted particles are injected, the bonding strength between particles is high, demonstrating the expected properties even under harsh conditions. The material name is R-A. The main component is Al2O3. The coating characteristics also have high electrical insulation properties, making it a key player in the high-temperature electrical insulation field.

Q1. How hard is the coating? It varies depending on the thermal spray material, but typically it is Hv500 to 1000. Q2. Why is it sticking? This is referred to as the anchoring effect. Q3. Is there no risk of it peeling off? It can peel off due to rapid heating, rapid cooling, or substrate corrosion. Q4. Is thermal spraying possible on the inner diameter? Of course, it is possible. However, there are restrictions for small diameters (less than 100 mm), so please consult us. Q5. What is the delivery time? It is usually about 3 weeks, but we can also accommodate urgent requests, so please consult us. For more details, please download the catalog.

Thanks to NCI's achievements in localized thermal spraying, we can fully leverage the advantages of plasma spraying. Plasma is a state of gas at extremely high temperatures where molecules dissociate into individual atoms, and electrons are further released. The plasma spraying method uses this super energy as a heat source to melt the coating material, which is then accelerated by a converged plasma jet of explosively expanding gas and coated onto the substrate.

Alumina has a hardness second only to diamond, with a melting point of 2,050 degrees. Due to its excellent heat resistance, chemical resistance, wear resistance, and electrical insulation properties, it is used in a wide range of applications. Additionally, zirconia, with a thermal expansion rate close to that of metals, is a key material for heat-resistant coatings. Recently, its latent functionalities, such as ion characteristics, have garnered attention in future-oriented fields, including fuel cells. Chromia forms the densest thermal spray coatings. Its primary application is as a wear-resistant coating for sliding components. For more details, please download the catalog.

In the manufacturing process of resin-based products such as films, the fineness and characteristics of the roll surface are crucial for product quality. Of course, the synergistic effect with the finishing polishing treatment is also significant, but certain types of ceramics have very high release properties against plastics and molten glass, and when sprayed, they can meet quite stringent requirements for scratch resistance and surface roughness. In extreme cases, it is even possible to treat surfaces so that adhesive tape does not stick. The high release properties are also beneficial for mold processing.

No matter how excellent the coating itself is, if the surface shape is not finished as designed, the expected performance cannot be achieved. NCI can adjust surface roughness from fine super mirror finishes to coarse non-processed surfaces, down to the nanoscale, enabling the creation of surfaces that are smooth or rough, easy or difficult to slide on, easy or difficult to adhere to, and easy or difficult to peel off. It is truly a craftsmanship born from skill. Of course, the experience as a pioneer in thermal spraying in Japan is also utilized in pre-treatments such as blasting and machining, as well as post-treatments like sealing.

The heat resistance and thermal insulation of ceramics have been proven even in outer space. They can protect the base material from cracking under sudden thermal loads. For example, by applying a ceramic coating to the piston head of a diesel engine, not only is the lifespan of the piston extended, but the high temperatures in the combustion chamber are maintained, improving combustion efficiency. Ceramic thermal spraying demonstrates its true value in extremely important parts that enhance the overall performance of devices, such as cylinder heads and gas turbine combustors.

Among materials with high insulation properties, ceramics are not only resistant to high temperatures but can also accommodate complex shapes through the localized process. Moreover, by utilizing ceramic thermal spraying, it is possible to create composite functions where one side is an insulator and the other is a conductor. Its excellent characteristics hold various possibilities, such as being used as insulating components for "Tristan," which controls high energy, high-frequency hardening coils with complex shapes, insulation measures for carbon, a high-temperature electrical material, and even in semiconductor manufacturing equipment.

In environments prone to corrosion, such as chemical plants, there may be additional requirements for heat resistance and wear resistance. Moreover, this can last for an extended period... A slight amount of corrosion or trouble can continue to spread over time, leading to significant damage to the entire facility. With ceramic coatings, we can flexibly respond to severe demands. From storage tanks to mixers, pumps, valves, and various other equipment, they demonstrate protection performance that does not diminish. For more details, please download the catalog.
