Core Products: Cermet Coatings Engineered for High Pressure and Extreme Abrasive Wear
Titanium Carbide (TiC), as a cermet material, boasts a hardness (Hv 2800-3200) exceeding conventional tungsten carbide, alongside higher thermal stability and lower density. We combine it with a ductile metallic phase to create a surface engineering solution with unparalleled performance.
Defining the Strength Standard for Ultra-High Pressure Valve Cores
Under ultra-high pressure conditions, the valve ball surface endures enormous Hertzian contact stress. Our High-pressure valve hard coated ball benefits from the extremely high hardness and excellent resistance to plastic deformation of the TiC-based coating. It effectively resists indentation and deformation caused by the seat under extreme specific pressure, ensuring the long-term geometric integrity of the sealing pair at Class 1500, 2500, and even higher ratings, preventing seal failure due to surface "collapse" of the ball.
Conquering the Most Severe Abrasive Wear – The Case of Slurry Service
For the most destructive conditions in mineral processing, such as TiC coated ball for mining slurry valve applications, the hardness advantage of the TiC coating is fully leveraged. It effectively resists the micro-cutting and ploughing action of high-hardness particles like quartz sand and corundum, offering a wear life that can be 30%-50% longer than conventional tungsten carbide coatings. This makes it the ultimate wear-resistant core for valves in slurry pump discharge lines, slurry diverters, and heavy media separation systems.
Superior Resistance to Metal-to-Metal Adhesive Wear
Under high-pressure, boundary-lubrication conditions, metal surfaces are prone to cold welding and material transfer. The Titanium carbide coated valve ball surface, due to its ceramic nature, has very low mutual solubility with most counterface metals (e.g., stainless steel, alloy steel seats), significantly reducing the risk of adhesive wear. This ensures valve operability and sealing repeatability under severe conditions.
Adaptive Design of TiC-based Composite Coatings
The TiC-based wear-resistant valve ball we provide is not a single formulation. By adjusting the size and morphology of the TiC particles and their ratio to the metallic binder phase (e.g., Ni, Co), we can customize the coating's hardness, toughness, and residual stress state to perfectly match diverse complex conditions, from pure wear in high-pressure water to corrosive slurry service.
Technical Focus: Reactive Thermal Spray Technology for Achieving Strong, Tough TiC Cermet Coatings
The core of the process is achieving a strong bond between the hard, brittle TiC and the metal while preserving its excellent properties. We primarily employ advanced processes combining High-Velocity Oxygen Fuel (HVOF) spraying with reactive flame spraying.
Simultaneous In-Situ Synthesis and Densification:
In reactive spraying, we use titanium metal and carbon-containing gas or solid precursors. An in-situ synthesis reaction occurs within the supersonic flame, directly generating the TiC coating on the substrate surface. This process results in fine, uniformly distributed TiC grains and forms a unique metallurgical bond with the substrate, yielding an extremely dense coating.
Nanostructuring and Precise Residual Stress Control:
Through process control, we can introduce nano-scale TiC reinforcement phases into the coating and precisely regulate the cooling rate to introduce beneficial compressive stress within the coating. This synergistic effect of "nano-reinforcement + compressive stress" allows the coating to effectively suppress crack initiation and propagation under extreme external loads, achieving a perfect unity of hardness and toughness.
Coating System Design for High-Pressure Service:
For theTiC coated valve ball, we employ a special structure of "graded transition layer + nanocomposite working layer." The graded layer mitigates thermal stress, while the working layer provides the main wear-resistant body. After spraying, the ball undergoes fine, mirror-grade grinding. This ensures that every point on the ball's surface, at micron-level precision, can uniformly withstand high pressure, avoiding early failure due to local stress concentration.
Why is TongBall's Titanium Carbide-based Coating the Necessary Choice for High-Pressure, High-Wear Service?
Materials Scientist in the Field of High-Pressure Wear Resistance:
We not only provide coating services but also delve deeply into the micro-design of TiC-based composites. We offer a surface system customized for high-pressure, high-stress conditions based on a materials genome concept, not merely a surface covering.
Mastery of Consistent Processes from Lab to Industry:
We possess the capability to transform cutting-edge coating technologies, such as reactive synthesis and nano-compositing, into stable, repeatable industrial production processes. This ensures every batch of TiC coated valve ball leaving our factory carries top-tier laboratory performance.
Committed to Solving Acknowledged "Hard Nuts" in the Valve Field:
We focus on those pain-point applications where the dual extremes of pressure and wear lead to extremely short valve life. Choosing our TiC solution means opting to fundamentally change the component's failure mode at the materials science level, pursuing an order-of-magnitude improvement in lifespan, not just a percentage gain.
When Pressure and Wear Together Weave the Most Demanding Failure Map
If your valve simultaneously withstands pressures of hundreds of bar and the continuous scouring of hard mineral particles, then mere "hardness" or "toughness" alone may be insufficient. TongBall's Titanium Carbide-based Coating Technology aims to provide a fundamental, long-lasting solution for these conditions where mechanical and wear limits are superimposed, by creating a "cermet" surface that combines ceramic hardness with metallic toughness.
