Spherical Al₂O₃-TiO₂ (aluminum oxide-titanium dioxide) thermal spray powders are ceramic coating materials composed of a blend of aluminum oxide and titanium dioxide. Common commercial grades include: AT3, AT13, and AT40 are produced via a spheroidization-granulation process, resulting in near-spherical particles—distinct from the angular powders typically obtained through conventional melting and crushing methods.
The aluminum oxide (alumina) component provides high hardness, wear resistance, and electrical insulation, while the titanium oxide (titania) component mitigates the inherent brittleness of ceramic coatings, enhancing toughness, density, and adhesion to the substrate, thereby reducing the risk of cracking. Once applied, these materials form smooth, dense ceramic coatings that offer excellent resistance to wear, cavitation, and corrosion from weak acids and alkalis, along with superior electrical insulation properties. They are suitable for long-term use at temperatures up to 540°C.
These powders are widely used for components such as hydraulic plungers, mechanical seal rings, butterfly valves, textile machinery parts, fan impellers, pump shafts, printing rollers, and insulating components. They serve as a primary choice of ceramic powder for thermal spraying—used for surface strengthening, corrosion protection, and wear-resistant repairs—and are compatible with standard thermal spray systems, including Atmospheric Plasma Spraying (APS), High-Velocity Oxy-Fuel (HVOF) spraying, and flame spraying.
Production Process for Spherical Alumina-Titania Thermal Spray Powders
Raw materials (high-purity alumina and titania powders) → Proportioning and mixing → Wet ball milling (refining) → Slurry preparation → Spray granulation → Drying and pre-calcination → High-temperature plasma spheroidization → Rapid solidification → Classification and screening → Iron and impurity removal → Particle size re-verification → Composition and flowability testing → Final packaging and warehousing.
Process Advantages: Plasma spheroidization allows the particles to melt and assume a spherical shape driven by surface tension. This results in significantly better flowability compared to crushed powders, ensuring uniform powder feed, reducing the likelihood of spray gun clogging, and providing greater consistency in coating quality. Packaging System for Spherical Aluminum-Titanium Oxide Thermal Spray Powders
Inner Packaging: Double-layered, sealed aluminum foil bags or PE inner liners, designed to be moisture-proof and leak-proof.
Outer Packaging: 25 kg per container (cardboard or steel drums) with sealed, clamped lids.
Unitization: Individual drums are labeled with product details (grade, batch number, particle size, and net weight); pallets are wrapped in stretch film for stabilization, moisture protection, and impact resistance.
Custom labeling and shipping marks are available upon request.
Transportation System
Road Transport: Domestic long-haul trucking; offers reliable lead times—ideal for short-distance transport and large-volume spot orders, with full-process visibility.
Ocean Freight: Containerized, palletized shipments; best suited for long-distance international bulk orders, offering significant cost advantages.
Air Freight: For urgent samples or small-batch rush orders; ensures rapid delivery, processed in accordance with standard air cargo regulations for general goods.
Rail Transport: Includes China-Europe freight trains and domestic rail lines; suitable for long-distance cross-border bulk shipments, balancing delivery speed with freight costs.
