Q1. How hard is the coating? It varies depending on the thermal spray material, but typically it is between Hv500 and 1000. Q2. Why is it sticking? This is referred to as the anchoring effect. Q3. Is there no risk of peeling? Peeling can occur 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.

The materials that can be thermally sprayed by NCI 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 re-melted in an atmosphere of about 1100°C after being thermally sprayed to create an alloy layer that forms a dense, pore-free coating that adheres to the base material. They are characterized by excellent wear resistance. For more details, please download the catalog.

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.*

We would like to introduce a case of regenerating cast iron plates with ceramic coating. The customer faced issues with scratches and rust due to wear, leading to a decline in precision and quality, and wanted to find a solution since ceramic (sintered) plates are expensive.

This method reduced costs compared to ceramic plates and eliminated the drawbacks of "chipping" and "cracking." 【Case Overview】 ■Challenges - Scratches and rust due to wear leading to a decline in precision and quality - Need for a solution since ceramic (sintered) plates are expensive ■Results - Cost reduction compared to ceramic plates, with no drawbacks of "chipping" or "cracking" - Reduced occurrence of rust, which is a drawback of cast iron plates *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where worn parts were entrusted to us, and SUS thermal spraying was performed on the bearing section, while ceramic thermal spraying was done on the seal section. The customer faced the challenge of having to stop the equipment and replace parts due to wear on the sealing surfaces and bearing sections, and purchasing from the manufacturer resulted in high costs for individual parts. After performing thermal spraying and having the parts assembled and operated, we found that compared to solid metal parts, wear was reduced and the frequency of replacements decreased. 【Case Overview】 ■Challenges - The need to stop the equipment and replace parts due to wear, with high costs for individual parts when purchased from the manufacturer. ■Results - Wear was reduced compared to solid metal parts, and the frequency of replacements decreased. - Costs were lower than purchasing from the manufacturer. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study on "the regeneration of mechanical seals" that we conduct. Our customers face challenges such as high costs associated with replacing seals with new ones each time, and while having spare parts would be beneficial, the inventory costs can also be significant. At our company, we take in the removed items, rewrap the sealing materials, perform maintenance cleaning, replace parts, and return them after repair and regeneration. This leads to cost reduction, shorter delivery times, and helps keep inventory costs down. [Case Overview] ■ Challenges - If there are no spare parts, delivery times are extended, which may not meet project deadlines. ■ Results - Leads to cost reduction and shorter delivery times, while also keeping inventory costs down. - Allows for unexpected responses, contributing to better management of project timelines during regular maintenance. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where the surface roughness equivalent to HCr plated rolls was reproduced using ceramic spraying and implemented in production maintenance. The customer faced a challenge where using metal rolls and HCr plated rolls resulted in defects in the produced products due to scratches on the roll surface, necessitating roll replacement work. As a result of the implementation, the new rolls were harder than HCr plated rolls, less prone to scratches, and did not produce burrs, leading to a reduction in defects in the products and a decrease in costs associated with roll replacement. [Case Summary] ■Challenge - Defects in produced products due to scratches on the roll surface, requiring roll replacement work. ■Result - Reduction in defects in products and a decrease in costs associated with roll replacement. *For more details, please download the PDF or feel free to contact us.
