DLC (Diamond-Like Carbon) coatings occupy a specific position in the thin-film coating spectrum: very high hardness with diamond-like hardness characteristics, extremely low friction (COF 0.05 to 0.1), and chemical inertness, all applied at 1 to 4 µm without altering part dimensions. These properties make DLC coating the standard specification for components where sliding friction, surface reactivity, or […]

Coating thickness is one of the most frequently discussed specifications in PVD and DLC applications, and one of the most commonly misunderstood. The assumption that thicker coatings provide better protection is intuitive but incorrect for thin-film vacuum deposition. In PVD and DLC, performance comes from the coating's material properties, including hardness, friction, thermal stability, and […]

A PVD coating is only as reliable as the surface it bonds to. The most advanced coating applied to a contaminated or improperly prepared substrate will delaminate, chip, or wear through faster than an entry-level coating applied to a properly prepared substrate. Surface preparation is not a preliminary step that happens before the real work begins. It […]

Sustainability in manufacturing is not just about energy consumption or raw material sourcing. It extends to every process that determines how long a part lasts, how often it needs replacement, and what chemicals are generated during surface finishing. PVD and DLC surface coating processes sit at the intersection of performance and environmental responsibility, providing measurable gains in […]

Most protective coatings are only a few microns thick, yet that thin layer often decides whether a part lasts one shift or thousands. When a component fails earlier than expected, the cause usually traces back to its surface rather than its core. Wear, galling, and corrosion begin where two parts meet, and that point of […]

In motorsport, gains are measured in fractions. Fractions of a second on the clock, fractions of a degree in operating temperature, fractions of a millimeter in component wear after a race-length session. At this level, the surface of every moving part matters. How much friction it generates, how much heat it retains, how much material […]

A coating that protects an aerospace bearing operating at 700°C has almost nothing in common with a coating that protects a firearm's slide cycling in desert conditions. The substrate is different. The failure mode is different. The documentation requirements are different. Yet both require precision application, data-backed selection, and quality-controlled processes from the same facility. […]

Coating selection should not start with a coating name. It should start with the part, the operating conditions, and the way that part fails or wears in service. Yet engineers and buyers frequently default to a familiar specification or accept a vendor's standard recommendation without evaluating whether it actually fits the application. Advanced Coating Technologies […]

Every coated part that fails in the field can usually be traced back to a mismatch between the coating's properties and the application's actual demands. Not a defective coating. Not a bad substrate. A selection problem. At Advanced Coating Technologies, we see this pattern: an engineer or buyer specifies a coating based on familiarity or […]
