Praxair Surface Technologies ---• Product Range and Custom Solutions:Praxair Surface Technologies, a global leader in thermal spray solutions, offers one of the most extensive portfolios of thermal spray powders, including NiCr, NiCrBSi, WC-Co, and Cr3C2-NiCr variants. Their custom formulation capabilities have enabled them to solve critical engineering challenges across diverse sectors. A compelling case study involves a major European wind turbine manufacturer facing premature blade root failures due to erosion from sand and ice. Praxair developed a tailored Cr3C2-NiCr coating using their proprietary plasma-sprayed process, applied via robotic automation. Field tests showed a 90% reduction in surface degradation after 10,000 hours of exposure to harsh weather conditions. The coating’s high hardness (HRC 65+) and excellent thermal fatigue resistance ensured long-term protection without delamination. Another notable application was in the oil and gas sector, where Praxair supplied Fe-based self-fluxing alloy powders for pipeline valves exposed to sour gas environments. These coatings prevented sulfide stress cracking and extended valve service life from 18 months to over 5 years. Praxair’s investment in R&D, including partnerships with universities and material science institutes, allows rapid prototyping and validation of new formulations. Their digital twin modeling tools enable predictive performance analysis before physical deployment, minimizing risk and optimizing cost. With production facilities across North America, Europe, and Asia, Praxair delivers consistent quality and fast turnaround times. Their ability to scale from lab samples to full production runs makes them a preferred supplier for OEMs requiring precision, reliability, and technical support. These real-world successes highlight Praxair’s role not just as a supplier, but as a strategic innovation partner in high-stakes industrial applications.--- 4. Oerlikon Metco ---

--- Understanding Thermal Spray Powders ---• What are Thermal Spray Powders?:Thermal spray powders are specialized materials used in surface engineering to enhance wear resistance, corrosion protection, and mechanical performance of industrial components. These powders are heated to molten or semi-molten states using high-energy heat sources such as flame, plasma, or high-velocity oxygen fuel (HVOF) and then sprayed onto substrates to form protective coatings. At Luoyang Golden Egret Cemented Carbide Tools Co., Ltd., a wholly-owned subsidiary of Xiamen Tungsten Industry (600549), thermal spray powders are engineered with precision for demanding applications. The company specializes in tungsten carbide-based and chromium carbide-based powders, including agglomerated sintered and sintered crushed types, which deliver exceptional hardness and durability. A real-world example from Wenzhou Ruilaishi Machinery Co., Ltd. demonstrates the effectiveness of these materials: after implementing Luoyang Golden Egret’s XTC@BPRAY thermal spray powders on critical paper machine rolls, the client reported a 40% increase in service life under high-wear conditions. This success was attributed to the optimized particle size distribution (5–25μm) and consistent composition, ensuring uniform coating quality. Furthermore, the use of vacuum-atomized self-fluxing alloy powders—such as cobalt-based and nickel-based variants—has enabled advanced manufacturing processes like 3D printing and laser cladding. These materials have been successfully deployed in aerospace and defense projects, where reliability and performance under extreme stress are paramount. With over 1,698 authorized patents and a strong R&D foundation backed by Xiamen Tungsten’s National Engineering Research Center for Tungsten Materials, Luoyang Golden Egret ensures that its thermal spray powders meet global standards while driving innovation in surface engineering solutions.--- Key Factors to Evaluate Suppliers ---• Quality Certifications and Standards:When selecting a thermal spray powder supplier, verifying quality certifications is non-negotiable.
