PLUNGER



With an outer Ni-Cr self-fluxing alloy coating, it achieves metallurgical bonding rather than the mechanical adhesion of conventional HVOF thermal spraying, delivering fivefold higher strength bonding, hardcore solving the pain points of industry.
Conventional thermal‑spray coatings rely on mechanical adhesion and exhibit porosity. Our advanced process achieves metallurgical bonding and delivers superior durability, along with low residual stress, minimal thermal impact on the substrate, ultra-low dilution, and crack‑free coatings.
With ultra‑high wear resistance and corrosion resistance, it ensures long‑term stable equipment operation and lays a solid foundation for core component development in the high‑quality advancement of the energy and hydraulic industries.
The core performance of the product meets the industry’s most stringent requirements:
Coating Hardness: 62-65HRC
Coating Thickness: 0.5-0.7mm
Surface Finish: Ra0.02-Ra0.2
