Dykron coating (wear resistance, heat resistance, adhesion, erosion resistance, cavitation resistance, dimensional accuracy)
■Excellent Characteristics 1. Good Wear Resistance Dykron has a hardness of around Vickers hardness HV1000. 2. Strong Adhesion to the Base Material Using a unique mixed catalyst for Dykron coating that has strong adhesion to the material, we have enhanced the adhesion to the base material. As a result, it forms a coating with a high intermolecular bonding force with the base material. There is almost no visible cracking or peeling even when subjected to bending after treatment, which is impossible with ceramic or metal thermal spraying and hard chrome plating. However, it may be affected by repeated bending exceeding several dozen times. 3. Good Heat Resistance By diffusing non-metallic elements into the material and electrically depositing the coating layer, it exhibits excellent performance against heat shock from rapid heating and cooling, and the treated material maintains a hardness of HV800 even at temperatures of 400°C, so its performance is hardly reduced at high temperatures. *It also has properties that make it difficult to experience seizure. 4. High Dimensional Accuracy of the Surface Compared to hard chrome plating, there is less variation in film thickness due to ingenuity in jigs and other tools. Due to its high hardness, it depends on the condition of the surface preparation, but a mirror finish (a smooth surface like a mirror) is also possible. Post-processing such as polishing and grinding is also possible.

basic information
■Details of Processing Technology 1. It is an electrolytic hard chromium plating. It is a non-standard chromium plating processed without using any catalysts specified by standards, utilizing a unique catalyst bath. The surface is harder compared to conventional hard chromium plating (around HV1000). 2. It complies with the RoHS directive and the Food Sanitation Act (Ministry of Health, Labour and Welfare Notification No. 370). 3. Processing is possible for almost all metal materials. *However, processing is not possible for titanium, cemented carbide, nitrided materials, or those that have undergone surface treatment. ■Available Processing Sizes The size of the processing tank is 1000W x 1000H x 3000L. Processing will be done within this range. However, depending on the shape, it is also possible to process larger items through multiple treatments. (Consultation is required depending on the shape. Please inquire.) ■Base Materials Processing is possible for iron-based, SUS-based materials (including castings), aluminum-based, and copper-based materials. ■Delivery Time Approximately 2 weeks (shorter delivery is possible for reprocessing).

Applications/Examples of results
■ Wear-resistant applications Shafts, vent pipes for powder transport, surfaces of crushing rolls and shaft bearing sections, pulleys for drive belts (V-timing) for conveyor lines, blades (single tooth), guides and guide rolls for electric wires and fibers, chain rails, tanks, hoppers, and chutes for raw materials and products in pharmaceuticals, medicine, and food (also for preventing foreign matter contamination). ■ Erosion-resistant applications Pump bearing sleeves, impellers (rotating blades), casings (main body), rotating parts in stirrers that come into contact with liquids. ■ Heat-resistant (anti-seizing) applications Sliding parts of shafts and pistons in high-speed, high-temperature, and high-pressure environments.
