Stellite-Type Cobalt Alloy Powder 45-90 µm

Understanding Stellite-Type Cobalt Alloy Powders

Stellite-type alloys are cobalt-chromium-tungsten systems renowned for their extreme hardness, cavitation resistance, and ability to retain properties at high temperatures. In powder form, they are a standard choice for applying wear-resistant overlays via thermal spray processes. The 45-90 µm cut is a common, versatile distribution that balances deposition efficiency with coating density, making it suitable for a wide range of spray equipment.

Key Performance Characteristics

While the exact grade dictates the final properties, users typically select this family of powders for the following benefits:

• Wear Resistance: Excellent resistance to abrasion, galling, and erosion, even in harsh environments.
• Corrosion Protection: The cobalt-chromium matrix provides a strong defense against oxidation and chemical attack.
• High-Temperature Hardness: Retains significant hardness at elevated temperatures where steel-based alloys would soften.
• Low Friction Coefficient: Inherent lubricity helps reduce metal-to-metal wear in sliding contact applications.

Process Compatibility and Selection

The 45-90 µm particle size is generally compatible with HVOF, plasma spray, and some flame spray systems. The specific process choice depends on the desired coating density, oxide content, and application cost. HVOF typically yields the densest coatings with the highest bond strength, while plasma spray offers flexibility for a broader range of substrates.
