HTY

KYOCERA Hardcoating’s HTY Aluminum Titanium Nitride (AlTiN) is a high-performance PVD coating distinguished by its exceptional hardness, smooth surface finish, and striking purple-black appearance. Utilizing advanced magnetron sputtering technology, HTY offers superior wear resistance and thermal stability, making it ideal for machining applications involving low carbon and stainless steels, as well as materials prone to sticking or gumming.

Applications

Industrial & Manufacturing

Forming tools and dies for stainless and low carbon steels
Precision cutting tools requiring smooth chip evacuation and wear resistance
Wear components in high-speed or high-friction machinery
Tooling for sticky or gummy materials such as copper, nickel alloys, or soft titanium

Medical & Dental

Surgical instruments used on stainless or soft titanium
Tools requiring smooth surfaces for easy cleaning and sterilization
Biocompatible tooling and fixtures exposed to friction and wear

Aerospace & Defense

Machining tools for titanium alloys and corrosion-resistant steels
High-temperature wear components operating in dry or low-lubrication environments
Fasteners and fittings needing stable coatings under extreme load and vibration

Electronics & Precision Components

Tooling and dies used in fine stamping of conductive or adhesive-prone materials
Moving parts in thermal or electromechanical assemblies
High-precision mold inserts for clean surface finish and tight tolerances

Core Benefits

Exceptional Hardness: With a microhardness of approximately 3700 HV, HTY provides outstanding wear resistance, significantly extending the lifespan of components.
Low Coefficient of Friction: At 0.30, HTY reduces friction, minimizing heat generation and preventing material adhesion, which is particularly beneficial when working with sticky or gummy materials.
High Oxidation Resistance: Maintains integrity and performance at oxidation temperatures up to 1100°C (2010°F), ensuring reliability in high-temperature machining operations.
Smooth Surface Finish: The magnetron sputtering process results in a smoother coating surface compared to traditional cathodic arc deposition, reducing friction and improving chip flow.

Why Choose HTY Coating?

HTY stands apart from other high-performance coatings thanks to its ultra-smooth finish, produced through magnetron sputtering. This smoother surface significantly reduces friction and material adhesion, making it ideal for applications where cleanliness, surface quality, and consistent contact are essential. While other coatings focus on maximum hardness or thermal barrier performance, HTY is designed to minimize buildup, dragging, and contamination—especially in sensitive environments like medical tooling, fine forming dies, or tight-tolerance components.

It still delivers excellent hardness and heat resistance, but what truly sets it apart is how cleanly it runs—reducing edge pickup, improving release, and supporting finishes that other coatings may compromise. If your application demands both durability and precision surface control, HTY offers the right balance—protecting your parts without leaving a heavy footprint.

Deposition Process

Our HTY coating is applied using advanced Magnetron Sputtering Physical Vapor Deposition (PVD) technology. This process involves ejecting material from a target source onto the component’s surface in a high-vacuum environment, resulting in a thin, dense, and smooth ceramic layer. The magnetron sputtering technique ensures uniform coverage, excellent adhesion, and minimal impact on the component’s dimensional tolerances, making it suitable for precision applications.
