Cutting Tools & Molds

In modern CNC machining—such as high-speed dry cutting and the machining of difficult-to-cut materials—as well as in high-precision stamping and forming processes, tool and die surfaces are subjected to extreme mechanical stresses and thermal loads. PVD hard coatings are essential for extending tool life and enhancing machining accuracy. In this field, stringent requirements are imposed on target material regarding grain uniformity and density to suppress the ejection of large droplets during cathodic arc evaporation, thereby ensuring film smoothness and red hardness.

Automotive Components

In internal combustion engines for fuel‑powered vehicles—such as piston rings, valve tappets, and camshafts—and in the precision transmission systems of new‑energy vehicles, critical moving components must operate reliably over extended periods under lean‑oil or extreme‑pressure conditions. A low coefficient of friction combined with outstanding resistance to adhesive wear is essential for reducing energy consumption and improving mechanical efficiency. At the same time, the automotive industry—under the IATF 16949 standard—imposes exceptionally stringent requirements on batch‑to‑batch consistency of coating performance.

Hydrogen & Lithium Energy

In the global energy transition, metal bipolar plates for proton exchange membrane fuel cells (PEMFCs) and novel current collectors for solid-state batteries face severe challenges from highly acidic corrosion and high‑potential polarization. PVD coatings must not only completely seal the microchannels that allow corrosive electrolytes to penetrate the metallic substrate—requiring coating density approaching the theoretical limit with no pinholes—but also maintain extremely low interfacial contact resistance (ICR) and outstanding electrical conductivity.

High-End Decoration

In the fields of high-end watchmaking, jewelry and metal hardware, as well as 3C smart terminals (such as smartphone frames and wearable devices), PVD coatings not only provide scratch‑resistant and corrosion‑proof protection but also serve as the cornerstone for imparting products with a premium metallic texture and rich color expression. This sector imposes stringent yield requirements, demanding precise control over coating surface chromaticity—without any drift in Lab* values—and the complete absence of pinhole defects.

LOW-E glass

Building energy efficiency—low‑E glass, smart dimming glass, and flat‑panel displays—depends on large‑area, continuous vacuum magnetron sputtering production lines. Target dimensions can reach several meters; under long‑duration, high‑power‑density sputtering, even minor stress concentrations can readily cause ceramic targets to crack, while oxide targets are prone to forming “nodules” at the edges of the target tracks, triggering arcing and unexpected shutdowns and significantly reducing target utilization.

Semiconductor

In integrated circuit manufacturing and advanced packaging—such as the underbump metallization (UBM) layer in 2.5D/3D ICs and copper interconnect barrier layers—the tolerance for defects in sputtering targets is zero. With linewidths ranging from microns to nanometers, target materials must exhibit exceptionally high absolute purity—typically ≥4N to 5N—and stringent limits on contamination by alkali metals (Na, K), radioactive elements, and ultra‑small particulates (low particle count). Moreover, the target’s crystallographic orientation must be uniform to ensure perfectly consistent sputtering rates and step coverage across the entire wafer.

Biomedical

Orthopedic implants, such as artificial hip and knee joints, and cardiovascular stents are required to perform reliably over long periods in the highly corrosive bodily fluids of the human body, while also enduring severe friction and wear. Even more concerning is that potentially harmful ions—such as heavy metals like cobalt and nickel—leaching from the underlying metallic substrate can trigger serious biotoxicity and immune rejection reactions. Consequently, medical PVD hard coatings must not only exhibit exceptional density and wear resistance but also possess absolute biocompatibility and chemical inertness.

Magnetic Recording Storage

In the production of perpendicular magnetic recording (PMR) media for high-capacity hard disk drives (HDDs), it is necessary to magnetically sputter large quantities of ferrous, cobalt‑based, and nickel‑based magnetic alloy underlayers and recording layers. However, when using conventional magnetron sputtering with strongly ferromagnetic materials, the magnetic flux lines at the cathode surface become severely shielded, preventing the equipment from initiating and sustaining a stable discharge. Alternatively, the target material may thin excessively, resulting in extremely low utilization rates—often leading to the formation of narrow track grooves—and incurring substantial downtime costs associated with frequent target changes.
