Alumina Titania Powder (Al2O3 13TiO2) Description:
These powders, comprising alumina and approximately 13% titania (nominal), are formulated to create dense ceramic coatings with exceptional wear resistance, allowing for excellent surface finishes upon grinding. Compared to coatings of alumina with 13% titania or pure alumina, these materials generally exhibit higher toughness but lower hardness, dielectric strength, and somewhat reduced resistance to chemical corrosion. Operational temperatures of up to 540°C (1000°F) are viable for these coatings. Alumina Titania Powder (Al2O3 13TiO2) is particularly recommended for its resistance against abrasive grains, hard surfaces, fibers, threads, fretting, cavitation, and particle erosion. It finds applications in various fields including printing ink transfer rolls, textile components, petrochemical equipment (pump sleeves), mechanical seals, and electrical insulators.

FAQs
Q1: What is Alumina Titania Powder (Al2O3 13TiO2)'s composition ratio and performance advantages?
A1: The composition is 87% Al₂O₃ + 13% TiO₂. The high titanium content significantly improves the toughness and thermal shock resistance of the coating, which is suitable for high-impact and strong corrosive conditions.
Q2: What are the advantages compared with low titanium content (e.g. 3% TiO₂) powders?
A2.
Increased toughness: 20% increase in flexural strength (vs. 3% TiO₂)
Bond strength: ≥45 MPa (ASTM C633)
Corrosion resistance: 30% longer life in 10% H₂SO₃ solution.
Q3: What is the particle shape and size range of the powder?
A3: Near-spherical particles made by plasma spheronization process, standard particle size 15-53μm (suitable for plasma spraying), support customized 5-25μm (HVOF) or 75-150μm (arc spraying).
