Featured Solutions
M5™ Dual-Stage Combustion HVAF System.
Universal HVAF platform for HVOF-grade and ultrafine powders
The full M5 system features independently controlled primary and secondary combustion and supports multiple nozzle configurations. It is optimized for high-performance spraying of conventional HVOF-grade powders, while a simple nozzle change also allows processing of ultrafine powders for thin, precision coatings.
User Application Benefits
● Excels in spraying 15–45 µm HVOF-grade WC- and CrC-based powders, forming dense coatings with 1400–1500 HV₃₀₀ hardness and 58–60 % deposition efficiency.
● Applies metallic coatings characterized by low porosity, minimal oxidation and high adhesion strength.
● Equally effective with standard and super fine HVAF powder fractions for application of Flash Carbide coatings.
Advanced Technical Features Making This Possible
● High-Thermal-Efficiency Combustor — increases combustion completeness and flame stability, producing a uniform flame for improved particle heating.
● Independent MFC-controlled dual-stage combustion process — enables precise tuning of primary and secondary combustion zones, improving particle heating and deposition efficiency across all powder types.
G4™ High-Accuracy Gravimetric Powder Feeder
The G4 provides precise, pulseless powder feeding for stable and repeatable coating results. Its patented feeding mechanism and automatic feed-rate control ensure consistent powder delivery across a wide operating range.
● Automatic Feed-Rate Control – maintains the desired powder flow with exceptional accuracy
● Quick Start — reaches the set feed rate within seconds.
● Quick Stop — provides clean powder cut off without afterflow or overspray.
● Wide Feed-Rate Range — supports a broad spectrum of powder flow requirements.
M5™ Flash Carbide HVAF System
Specialized HVAF configuration for ultrafine carbide powders
A simplified single-stage M5 configuration developed specifically for ultrafine powders and Flash Carbide coatings. The system uses the same M5 spray-gun platform with a dedicated single-stage nozzle configuration and simplified gas delivery, providing a lower-cost solution for thin, smooth, dense carbide coatings.
The Flash Carbide package includes the M5 single-stage combustion HVAF gun, an MFC-based control system, and a G4 gravimetric powder feeder. It is optimized for ultrafine WC-based powders (2–15 µm), providing stable powder feeding, uniform particle heating, and precise coating thickness control.
The system produces thin, dense, low-porosity coatings suitable for near-net-shape and precision components.

Flash Carbide Coatings
Uniquecoat Flash Carbide is an ultra-thin, high-density WC-10Co-4Cr coating applied by the HVAF process and engineered to replace hard chrome and traditional HVOF coatings.
It is typically 25–35 µm thick, yet fully impermeable, achieving hardness 1500-1550 HV₃₀₀ with near-zero porosity and a low as-sprayed surface roughness (Ra ≈ 1.1–1.2 µm), eliminating the need for dimensional grinding.
The coating provides excellent resistance to wear, erosion, and corrosion, along with extended fatigue life and minimal substrate heating, making it well suited for near-net-shape and precision components such as hydraulic rods, plungers, and industrial rollers.
