Good toughness, low friction characteristics, and higher mechanical impact resistance, high wear and corrosion resistance, insoluble in acids, alkalis, and alcohol solutions, used for pump seal rollers, wear rings, operating temperature <540℃

Product Performance:

Chromium oxide-based ceramic composite powder is a ternary composite oxide powder primarily composed of chromium oxide, along with silicon oxide and titanium oxide. It has a melting point of 2300°C and a thermal expansion coefficient of 9.6×10⁻⁶ K⁻¹.

The powder spraying process offers excellent performance, with improved powder deposition efficiency, strong adhesion to the substrate, dense coating, and good wear resistance, making it the most wear-resistant among known chromium oxide coatings. The coating is dark ink-colored, a neutral to slightly acidic composite oxide, and exhibits excellent corrosion resistance.

Product Application:

This type of material has high hardness and a certain degree of toughness, exhibiting excellent and stable wear resistance and friction-reducing performance under conditions of insufficient lubrication and heat dissipation. The coating has a dense structure, and its surface can be polished to a controllable roughness with an "orange peel" surface morphology, providing an appropriate friction coefficient to give the spinning fibers moderate twist and tension. Additionally, the coating possesses semiconductive properties, which can eliminate static electricity caused by fiber friction.

Primarily used for chemical compressor shafts, plungers, piston rods, pump mechanical seal rings, wear-resistant rings, ring valves, flue gas fan blades, grinding and polishing fixtures, chemical fiber twisting spindle cups, chemical fiber hot roller groove cylinders, wear-resistant accessories for short fiber two-for-one twisters, and wear-resistant coatings for various textile machinery accessories.

Coatings can be prepared using processes such as gas-stabilized plasma spraying, water-stabilized plasma spraying, supersonic flame spraying, detonation spraying, or powder flame spraying (accelerated with compressed air).
