Why Nickel-Chrome for Thermal Spray?
Nickel-chrome (NiCr) alloys are widely specified as bond coats and build-up layers in thermal spraying. The chromium content promotes the formation of a protective oxide scale at elevated temperatures, while the nickel matrix provides toughness and adhesion. Typical coating characteristics include good resistance to oxidation, hot gas corrosion, and fretting wear. This makes NiCr a common choice under ceramic topcoats or as a standalone coating on shafts, journals, and boiler tubes.
Mesh Cut and Process Fit
The -140+325 mesh designation indicates a controlled particle size distribution: powder passes through a 140-mesh screen (approx. 105 microns) and is retained on a 325-mesh screen (approx. 44 microns). This mid-range cut flows smoothly through powder feeders and melts consistently in the thermal spray jet. It is compatible with combustion-driven processes (HVOF, flame spray) and plasma spray systems. If your equipment requires a tighter or coarser cut, let us know during the enquiry — we can discuss available alternatives.
Selection and Handling Tips
- Process match: Confirm your gun model and nozzle configuration before ordering. HVOF, plasma, and flame each have different thermal histories, and powder feed behaviour matters.
- Storage: Keep powder containers sealed and stored in a dry, temperature-stable environment. Moisture pickup can cause feeding inconsistencies and coating porosity.
- Trial batch: For new applications, start with a smaller pack size to validate deposition efficiency and coating microstructure before committing to volume.
