Anti Oxidation Tungsten Plate
Tungsten, as a strategic refractory metal, is highly favored due to its extremely high melting point (3422 ° C) and high-temperature strength. However, pure tungsten is highly prone to oxidation in high-temperature aerobic environments, generating volatile tungsten trioxide, leading to rapid material failure. Anti oxidation tungsten plate is a high-end material developed to address this core pain point.
It greatly improves the service life of materials in high-temperature aerobic environments by adding specific high-temperature resistant elements (such as potassium, silicon, etc.) to the tungsten matrix or preparing dense high-temperature protective coatings on its surface. This product is designed specifically for high-end manufacturing industries that pursue equipment stability and production continuity under extreme conditions.
Description
Many customers are well aware of the heat resistance of tungsten, but may not necessarily understand its fragility in aerobic environments. We clearly demonstrate the excellence of antioxidant tungsten plates through the following comparison:
| Comparison item | Traditional pure tungsten plate (common situation among competitors) | Our antioxidant tungsten plate |
| High temperature aerobic stability | Significant oxidation begins above 500 ° C, resulting in white or yellow powder on the surface and structural damage. | The antioxidant temperature has been significantly increased, and it can work for a long time in a specific high temperature range (such as 1200-1800 ° C) with a intact surface. |
| Service Life | Under cyclic thermal shock, rapid loss occurs due to oxidation pulverization, requiring frequent replacement. | Extend lifespan by 3-5 times, significantly reducing downtime for maintenance and spare parts costs. |
| Consistency Of Performance | The performance deteriorates sharply at high temperatures, and the dimensions of components constantly change due to oxidation, affecting the stability of the process. | High temperature strength retention rate, dimensional stability, ensuring repeatability of heat treatment, sintering and other processes and product consistency. |
| Application Cost | The cost of a single item is low, but the frequency of comprehensive maintenance and replacement is high, resulting in a high total cost of ownership (TCO). | The initial investment is slightly higher, but with its long lifespan and stability, the total cost of ownership (TCO) is significantly reduced. |
To ensure optimal performance and extended service life of the antioxidant tungsten plate, please follow the following guidelines:
1. Suggestions for work environment
- Ideal environment: Used in a vacuum or high-purity inert gas (such as argon, nitrogen) protective environment to maximize its service life.
- Aerobic environment use: If it must be used in an oxygen-containing atmosphere, please strictly follow the "Temperature Atmosphere Corresponding Operation Window" we provide to avoid overheating operations.
2. Installation and Operation
- Cleaning treatment: Before installation, please clean the board surface with anhydrous ethanol or acetone to avoid carbonization or reaction of pollutants such as oil stains and fingerprints at high temperatures.
- Uniform heating: The heating and cooling process should be slow and uniform, with a recommended rate of ≤ 10 ° C/minute to reduce thermal stress and prevent cracking.
- Load limitation: During design, its high-temperature creep performance should be fully considered to avoid long-term exposure to excessive tensile loads at extremely high temperatures.
3. Maintenance and Care
- Regular inspection: Regularly check the surface condition. If slight wear is found on the coating, you can consult us for the possibility of returning the coating to the factory for repair according to the situation, in order to save costs.
- Clean storage: After shutting down the equipment and cooling it to room temperature, remove the tungsten plate, clean it, and store it in a dry, dust-free environment.
We firmly believe that excellent products require comprehensive services to create maximum value for customers.
1. Pre sales technical support: Our engineering team will provide you with free technical consultation to assist you in confirming whether the material selection matches your process (temperature, atmosphere, load) and provide the best solution.
2. After sales guarantee:
- Quality commitment: The product comes with a material certificate. If it is confirmed to be a product quality issue, we promise to return or exchange the goods.
- Installation guidance: Provide detailed installation operation guide documents and video materials.
- Quick response: Set up an after-sales hotline, and for any problems you encounter during use, we promise to provide a preliminary response plan within 12 hours.
FAQ
Q: Q1: What is the maximum temperature at which antioxidant tungsten plates can be used in air?
A: A1: It depends on the specific brand and coating system. Our standard products can be used for a long time in an inert environment at 1600 ° C, and can withstand up to 1200 ° C for a short time in specific aerobic environments. Please provide your process parameters for accurate evaluation.
Q2: Can the board be bent or machined?
A2: Sure. But we strongly recommend performing mechanical processing first, and then applying an antioxidant coating to protect the integrity of the coating. We can provide raw materials, as well as undertake processing and coating services for incoming materials.
Q3: Can samples be provided for testing?
A3: For customers who have a genuine intention to purchase, we can provide paid samples, and the cost can be deducted from the payment after the order is confirmed.
