Chrome Oxide Coating Piston Rod

Product Description: Chrome Oxide Ceramic Coating Piston Rod

Our Chrome Oxide Coating Piston Rods feature a specially formulated chrome oxide (Cr₂O₃) based thermal spray coating. This advanced ceramic material creates a dense, well-bonded surface layer that offers excellent resistance to mechanical friction, abrasion, and corrosion, making it ideal for applications in petrochemical, paper, wire, and textile industries 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. With a typical chemical composition of 91.01% Cr₂O₃, 5.57% SiO₂, and 3.06% AlO₂, our chrome oxide coating delivers a unique combination of properties that provide exceptional protection and performance in demanding industrial environments.
