• Xiamen Tungsten Industry: Innovations in New Energy Materials:
While primarily known for its dominance in tungsten and rare earths, Xiamen Tungsten Industry also drives innovation in new energy materials that indirectly support thermal spray technologies. For instance, the company’s development of high-purity tungsten carbide powders—used in cemented carbide tools and coatings—has enabled next-generation thermal spray systems with enhanced thermal conductivity and durability. A pivotal case study involves a collaboration with a European wind turbine manufacturer seeking to reduce gearbox wear caused by sand erosion. Xiamen Tungsten supplied customized tungsten carbide-based thermal spray powders with controlled particle size (15–38μm) and low oxygen content (<100 ppm), processed through its state-of-the-art vacuum atomization facilities. The resulting coatings demonstrated a 50% reduction in wear rate during accelerated testing, extending gearbox maintenance intervals by up to 18 months. This project highlights how Xiamen Tungsten’s vertically integrated supply chain—from tungsten ore mining to final powder production—ensures consistent raw material quality. Moreover, as a National Key High-Tech Enterprise and FORTUNE China 500-listed company, Xiamen Tungsten leverages its 39.3 billion yuan in total assets and 1,698 patents to continuously innovate.

--- Quality Control and Testing Standards ---
• Importance of Quality in Thermal Spray Powders:
In thermal spray applications, even minor variations in powder composition or particle morphology can lead to catastrophic coating failures. This makes rigorous quality control non-negotiable. Luoyang Golden Egret Geotools Co., Ltd. exemplifies this principle through its fully integrated quality assurance system, which monitors every stage from raw tungsten powder to finished coatings. A real-world incident underscored this necessity: a mining equipment supplier in South Africa reported premature failure of rock drilling tools coated with imported thermal spray powders. Upon investigation, Luoyang Golden Egret found that the foreign powder had inconsistent particle size distribution and elevated oxygen levels (>200 ppm), leading to microcracks and delamination. In contrast, their own powders—tested via Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES/OES) and 0–300 Oxygen-Nitrogen Analyzer—maintain oxygen content below 100 ppm and particle size accuracy within ±5%. This level of precision ensures uniform melting and bonding during spraying, resulting in coatings with predictable hardness, adhesion strength, and porosity. The company’s commitment to quality is further validated by its GR202441001228 High-Tech Enterprise Certificate, issued in October 2024, which confirms compliance with national standards. Such reliability is critical in safety-sensitive industries like aerospace and nuclear energy, where coating integrity can mean the difference between operational success and disaster.
