Understanding Stellite-Type Cobalt Alloy Powder
Stellite-type alloys are cobalt-chromium-tungsten systems known for their exceptional resistance to galling, erosion, and high-temperature oxidation. In powder form, precisely sized for thermal spray, they become a versatile engineering solution for extending component life in demanding environments. The -170+325 mesh cut is a common specification for HVOF (High Velocity Oxygen Fuel) and plasma spray systems, balancing deposit efficiency with coating density.
Typical applications involve rebuilding worn shafts, protecting valve seats, coating pump sleeves, and applying hard-facing layers to components exposed to severe sliding wear or corrosive media. The powder's spherical or near-spherical morphology, confirmed on enquiry, is critical for smooth flow through powder feeders and consistent melting in the thermal spray jet.
Key Coating Characteristics
When sprayed with appropriate parameters, this powder yields coatings with a characteristic lamellar structure, low interconnected porosity, and high bond strength. The resulting surface exhibits a hardness profile that resists abrasive wear while the cobalt-chromium matrix provides a tarnish-resistant finish. Specific hardness values (HRC or HV) and deposition efficiency rates are process-dependent and will be shared with your technical enquiry.
Successful application depends on substrate preparation, spray parameter optimization, and proper powder handling. Our team can provide supporting technical documentation and connect you with application guidance to help achieve target coating specifications.
