日本コーティング工業 List of Products and Services

Nihon Coating Industry, established in 1961, is a professional group specializing in ceramic thermal spraying and surface treatment processing. Its high-level technology has been recognized, and in 1971, its thermal spraying technology was adopted for the M-4S rocket "Tansei," supporting advanced industries with ceramic technology for many years. No matter how excellent the coating itself is, if the surface shape is not finished according to the design, the expected performance cannot be achieved. We also flexibly respond to pre-treatments such as blasting and machining, as well as post-treatments like sealing. We offer proposals for high value-added technologies beyond thermal spraying. To provide our customers with high-quality thermal spraying technology accumulated over the years, we propose a consistent system from planning to spraying, delivery, and aftercare. We specialize in small-lot, diverse ceramic thermal spraying processing and can flexibly respond to proposals from the planning stage.

In the film sheet stretching process, even minor scratches on the roll surface are not permitted. Therefore, the "polishing" of the surface of the stretching roll becomes very important, and a high hardness that makes it difficult to scratch is required. We will introduce a case where our ceramic thermal spraying has solved this problem by improving wear resistance, reducing the transfer of scratches on the roll surface to the film, and enhancing release properties. ■Challenge To eliminate the transfer of scratches from the roll surface to the film and further improve wear resistance for longer usage. ■Proposal To improve wear resistance with a high hardness coating from ceramic thermal spraying, provide surface roughness polishing (from sub-mirror to super mirror) using NCI's unique finishing technology, and since recoating is possible after use, we proposed that we can finish and provide a reproducible surface roughness multiple times. ■Effect The lifespan was extended, the repair cycle became longer, maintenance costs were significantly reduced, and it contributed to increased productivity, which was greatly appreciated.

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 application includes spraying onto the inner wall of a case relative to turbine rotor blades to optimize the gap between the rotor blades and the case. Abrasive wear is a form of wear primarily caused by the cutting action of hard particles interposed between the uneven surfaces or gaps of contact surfaces. 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 form a coating on the substrate. Yttria (yttrium oxide) is an oxide of yttrium. *For more details, please download the PDF or contact us.*

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.
