1. Overview of Current Thermal Spray Industry Development
Surface protection technology has become an essential supporting technology for high-end industrial manufacturing. Thermal spraying is a cost-effective surface modification technology that deposits metal, ceramic or composite powder materials onto metal substrates to form functional protective coatings. It effectively solves core component failure problems caused by wear, high temperature oxidation, chemical corrosion and mechanical impact. In 2025, the global thermal spray material market maintains a 6.2% annual growth rate, driven by aerospace, new energy and petrochemical industrial upgrading.
“The stability of thermal spray powder determines 70% of the final coating performance, while spraying equipment and operation parameters only affect 30% of the finished effect.” — Global Surface Engineering Industry Association
1.1 Core Classification of Common Thermal Spray Processes
-
Plasma Spraying: Adapt to high-temperature ceramic powder, used for thermal barrier protection parts
-
HVOF Spraying: High bonding strength, suitable for wear-resistant alloy coating processing
-
Cold Spraying: Low construction temperature, no substrate deformation, for precision lightweight components
-
Arc Spraying: Low cost, large-area anti-corrosion construction for outdoor steel structures
2. Key Quality Evaluation Indicators for Thermal Spray Powder
Different from ordinary metal raw materials, thermal spray powder has strict customized physical and chemical indicators. Unqualified powder will cause coating peeling, pore cracking and short service life, increasing enterprise after-sales maintenance cost invisibly.
2.1 Mandatory Detection Indicators for Batch Delivery
-
Particle size distribution: Control particle diameter within 15μm-105μm according to spraying process
-
Powder fluidity: Standard Hall flow rate to ensure uniform automatic powder feeding
-
Microscopic morphology: Spherical powder is preferred to reduce spraying splash loss
-
Element purity: Control impurity content below 0.3% to avoid coating brittleness
-
Anti-caking stability: Adapt to long-distance sea transportation and cross-regional storage
