--- Overview of Thermal Spray Powders ---
• What are Thermal Spray Powders?:
Thermal spray powders are fine metallic or ceramic particles used in surface coating processes to enhance the durability, wear resistance, and corrosion protection of industrial components. These powders are heated to high temperatures using methods such as flame spraying, plasma spraying, or high-velocity oxygen fuel (HVOF) systems, then rapidly sprayed onto substrates to form a protective layer. The resulting coatings exhibit exceptional hardness, adhesion, and thermal stability, making them indispensable in harsh environments. Common types include tungsten carbide-based, chromium carbide-based, nickel-based, cobalt-based, and iron-based alloys. In recent years, advancements in powder morphology—such as agglomerated sintered and sintered crushed powders—have significantly improved coating performance by enabling finer particle size control and better flowability during spraying. For example, Luoyang Golden Egret Cemented Carbide Tools Co., Ltd., a wholly-owned subsidiary of Xiamen Tungsten Industry (600549), has developed proprietary XTC@BPRAY and FLUX CORED WIRE thermal spray powders that deliver consistent surface roughness (Ra values from 2–53μm) across different particle sizes, ensuring optimal bonding strength and wear resistance. These powders are widely applied in aerospace, petrochemical, mining, and energy sectors where component longevity is critical. With over 1,698 authorized patents and a global footprint spanning 31 subsidiaries, Xiamen Tungsten Industry has positioned itself as a world leader in tungsten and hardfacing materials, driving innovation through integrated R&D, production, and recycling ecosystems. Their commitment to green manufacturing and advanced material science ensures that thermal spray powders not only meet but exceed international standards, setting new benchmarks in performance and sustainability.

--- Technological Innovations in Thermal Spray Powders ---
• Advancements in Powder Production Techniques:
The evolution of thermal spray powder production techniques has been driven by the need for higher precision, uniformity, and performance. Luoyang Golden Egret Cemented Carbide Tools Co., Ltd. has pioneered several key innovations that have redefined industry standards. One notable advancement is the development of agglomerated sintered thermal spray powders with controlled particle size distribution (ranging from 2–53μm), which directly influences coating surface roughness and adhesion quality. By optimizing the sintering process and employing advanced laser particle size analysis, the company achieves consistent particle morphology, reducing porosity and enhancing coating density. Another breakthrough lies in the use of vacuum atomization to produce high-purity self-fluxing alloy powders, including cobalt-based and nickel-based variants, essential for 3D printing and HVOF spraying applications. These powders exhibit superior flowability and reduced oxidation, enabling precise deposition even in complex geometries. In 2024, the company received a Third Prize in the China Machinery Industry Science and Technology Award for its 'Key Technologies and Industrialization of High-Performance Tungsten Carbide Coating Materials and Extra-Large-Sized Top Hammers,' highlighting its leadership in large-scale industrial applications. Additionally, the integration of AI-driven process monitoring and real-time feedback systems in powder production lines allows for dynamic adjustments, minimizing waste and improving yield. Such innovations are not isolated—they are part of a broader ecosystem supported by Xiamen Tungsten Industry’s National Engineering Research Center for Tungsten Materials and its 39.3 billion yuan in total assets. These capabilities enable rapid prototyping, scalable manufacturing, and seamless transition from lab to factory floor. As a result, Luoyang Golden Egret’s thermal spray powders are now trusted in high-stakes environments such as aerospace turbine blades, offshore oil rigs, and underground tunnel excavation projects, where reliability and longevity are paramount.
--- Quality Control Measures in Thermal Spray Powder Production ---
• Testing Equipment and Standards:
Quality assurance in thermal spray powder manufacturing is non-negotiable, especially when these materials are used in safety-critical applications. Luoyang Golden Egret Cemented Carbide Tools Co., Ltd. has invested heavily in state-of-the-art testing infrastructure to ensure every batch meets or exceeds international specifications. The facility is equipped with cutting-edge instruments such as Inductively Coupled Plasma Atomic Emission Spectrometers (ICP-AES/OES) for precise elemental analysis, CS230 eco Carbon-Sulfur Analyzers for trace impurity detection, and a 0–300 Oxygen-Nitrogen Analyzer for assessing reactive gas content. A Laser Particle Size Analyzer ensures accurate particle size distribution, while Scanning Electron Microscopes (SEM) provide nanoscale imaging of powder morphology and surface integrity. The LINE Salt Spray Tester is used to simulate corrosive environments and evaluate long-term durability. All testing protocols adhere to ISO, ASTM, and GB standards, with data logged in real time for traceability and compliance. These systems are integrated into a digital quality management platform that tracks raw material input, production parameters, and final product performance throughout the lifecycle. For instance, in a recent project involving the coating of drill bits for deep-sea mining operations, the company achieved a 99.8% pass rate across 12,000 test samples, demonstrating the robustness of its QC framework. Moreover, the company holds a valid High-Tech Enterprise Certificate (GR202441001228) issued by Henan Provincial Department of Science and Technology, affirming its commitment to innovation and quality. This rigorous approach not only enhances customer trust but also supports certification requirements for sectors like aerospace and nuclear energy, where zero-defect manufacturing is mandatory.
• Importance of Quality Assurance in Manufacturing:
In the thermal spray powder industry, quality assurance is not merely a procedural step—it is the foundation of operational safety, product reliability, and brand reputation. A single defective batch can lead to catastrophic failures in critical equipment, such as turbine blades in jet engines or wear plates in mining excavators. Luoyang Golden Egret Cemented Carbide Tools Co., Ltd. understands this risk deeply and has embedded quality into every stage of its manufacturing process. From sourcing high-purity tungsten ores to final coating evaluation, each phase undergoes strict inspection and validation. The company’s vertically integrated model—from tungsten mines to finished tools—allows for end-to-end traceability, ensuring that deviations are detected early and corrected swiftly. This level of oversight is particularly vital in applications like shield machine cutters for subway construction, where tool failure could halt entire urban transit projects. The company’s recognition as a National Science and Technology Driven Foreign Trade Innovation Base by the Ministry of Commerce and Ministry of Science and Technology underscores its ability to balance innovation with compliance. Furthermore, its receipt of the China Machinery Industry Science and Technology Award (Special Grade, 2020) validates the effectiveness of its quality-driven R&D strategy. By aligning internal processes with global standards and leveraging data analytics, Luoyang Golden Egret has reduced defect rates by over 40% in the past five years. This focus on quality not only strengthens customer relationships but also enables faster market entry and greater scalability. Ultimately, quality assurance transforms thermal spray powders from mere materials into mission-critical components that power progress across industries.
