HTS

HTS is an advanced bilayer PVD coating that combines the durability of Aluminum Titanium Nitride (AlTiN) with the hardness and heat resistance of Titanium Silicon Nitride (TiSiN). This unique combination results in a bronze-colored coating that excels in demanding applications involving difficult-to-machine materials such as titanium alloys, hardened steels, cast irons, superalloys, and stainless steels.

Applications

Aerospace & Defense

Cutting tools and wear components for titanium and nickel-based superalloys
High-temperature tooling for structural components and precision fittings
Fixtures exposed to repeated thermal cycling and mechanical vibration

Automotive & Powertrain

Machining tools for hardened and alloy steels in engine and drivetrain parts
Cutting or forming components subjected to sustained stress and thermal load
Surface-treated parts for high-load, temperature-sensitive assemblies

Industrial & Manufacturing

End mills, drills, and inserts used on hardened steels and cast irons
Forming tools and die inserts for wear-intensive operations
Components exposed to both abrasion and heat in dry or high-speed conditions

Tool & Die / Precision Systems

Dies, punches, and core tools working with abrasive or heat-resistant materials
Molds for reinforced polymers or metal-forming applications
Precision tooling requiring edge stability and extended performance life

Core Benefits

Enhanced Durability: The AlTiN layer provides exceptional toughness and impact resistance, ensuring prolonged tool and component life.
Superior Hardness: The nanocomposite TiSiN layer contributes to a high microhardness of approximately 3600 HV, offering excellent wear resistance.
High Thermal Stability: With an oxidation resistance up to 1150°C (2100°F), HTS maintains performance in high-temperature environments.
Versatile Performance: Effectively handles a variety of challenging materials, making it suitable for diverse applications across multiple industries.

Why Choose HTS Coating?

HTS offers a next-generation solution for components and tooling exposed to the toughest material and temperature combinations. This bilayer coating merges the impact-resistant durability of AlTiN with the hardness and thermal performance of nanocomposite TiSiN. The result is a bronze-colored finish built for exceptional wear resistance, oxidation stability, and edge retention—even in hardened steels, superalloys, and other difficult-to-machine materials.

What sets HTS apart is its versatility under stress. Whether you’re facing high heat, heavy mechanical load, or long cycle times, HTS protects your tools and parts from breakdown while maintaining surface integrity. It excels in environments where both sharpness and structural toughness matter—especially in applications that involve dry machining, cast iron cutting, or high-pressure forming. For manufacturers demanding top-tier performance across a variety of high-stress conditions, HTS delivers both strength and staying power.

Deposition Process

The HTS coating is applied using advanced Physical Vapor Deposition (PVD) technology. This process involves the sequential deposition of AlTiN and TiSiN layers in a high-vacuum environment, resulting in a thin, dense, and adherent ceramic coating. The PVD technique ensures uniform coverage, excellent adhesion, and minimal impact on the component’s dimensional tolerances, making it suitable for precision applications.
