Alumina-Titania Coating Piston Rod

Product Description

Our Alumina-Titania Coating Piston Rods feature a specially formulated aluminum oxide combined with titanium oxide thermal spray coating. This advanced ceramic composite material creates a durable surface layer that effectively protects against thermal shock and mechanical friction, making it ideal for applications where conventional coatings would rapidly deteriorate.

The coating is applied using state-of-the-art thermal spray technology, which ensures optimal adhesion and uniform coverage. Available in multiple composition ratios of Al₂O₃ and TiO₂, our piston rods can be tailored to meet specific application requirements, providing the perfect balance of hardness, conductivity, and thermal shock resistance for your particular operating environment.
