TiCN Carbonitride Alloy Twin Screw Extruder Screw Elements with Superior Wear and Corrosion Resistance for Lithium Battery Slurry Mixing

As the demand for high-performance lithium battery materials continues to rise, the requirements for slurry mixing equipment become increasingly stringent. To meet these challenges, ZHITIAN has developed TiCN (Titanium Carbonitride) screw elements for twin screw extruders — a pioneering material breakthrough that combines hardness, toughness, and long-term durability in one solution.

Unlike conventional high-speed tool steels or standard PM-HIP alloys, TiCN alloy integrates the exceptional hardness of titanium carbide (TiC) with the excellent toughness of titanium nitride (TiN). This unique balance enables it to withstand the demanding abrasion, chemical corrosion, and mechanical shock conditions typical of lithium battery slurry production.

ZHITIAN’s engineering team has optimized TiCN’s powder metallurgy composition and sintering parameters to achieve a uniform microstructure, ensuring consistent wear and corrosion resistance across every screw element.

This innovation extends the service life of screw elements in continuous mixing lines and significantly reduces maintenance frequency and downtime.

In cathode and anode slurry processing, abrasive and corrosive particles—such as conductive carbon black, NCM, or LFP powders—constantly erode the working surfaces of screw elements.
ZHITIAN’s TiCN screw elements are engineered to handle these dual challenges by:

Resisting abrasive wear from fine solid particles;

Preventing chemical corrosion from NMP and lithium compounds;

Maintaining mechanical integrity under high torque and pressure;

Ensuring smooth flow and mixing through precise geometry and surface finish.

ZHITIAN provides TiCN screw elements as OEM-compatible parts for major twin screw extruder brands.
Each component is reverse-engineered and manufactured according to OEM standards, ensuring perfect fit, torque transmission accuracy, and long service performance.

Custom designs are also available to optimize mixing, kneading, and conveying performance based on slurry rheology and process parameters.

Every TiCN screw element undergoes strict testing, including:

Alloy composition analysis (XRF / SEM inspection)

Wear and corrosion simulation testing

Dimensional verification with CMM (Coordinate Measuring Machine)

Performance traceability via production batch documentation

This ensures each product meets the highest precision and durability standards required for lithium battery mixing systems.

Extended service life in abrasive and corrosive slurry environments

Improved mixing uniformity and process stability

Reduced maintenance frequency and equipment downtime

Custom OEM compatibility for various twin screw extruder models

Material innovation exclusive to ZHITIAN

Q1: What makes TiCN better than standard tool steel?
TiCN offers a superior combination of hardness and toughness, maintaining wear resistance without brittleness, which is ideal for lithium slurry applications.

Q2: Can TiCN screw elements replace OEM parts directly?
Yes. ZHITIAN provides precision-engineered TiCN elements compatible with major extruder brands, ensuring exact fit and performance consistency.

Q3: Is TiCN suitable for both cathode and anode slurry?
Absolutely. Its chemical stability and mechanical resilience make it ideal for both LFP, NCM, and graphite-based slurries.

Q4: Can surface coatings be applied on TiCN elements?
Generally not required—TiCN’s surface hardness and stability eliminate the need for secondary coatings in most mixing conditions.
