Hard Film Names ›

🔹 Recognizable by its gold color. Hardness: ~2300 HV. Common on drill bits, end mills, and molds. Offers good wear resistance and reduces friction.

When discussing surface engineering and thin-film technology, the term “hard film” refers to coatings that significantly improve a material’s resistance to wear, scratching, corrosion, and heat. But the naming of these hard films can be confusing. Let’s break down the most common “hard film names” you’ll encounter. hard film names

🔹 A popular hard film known for its low friction and high hardness (often up to 3000–5000 HV). Used in automotive engine components, razors, and medical devices. Its name reflects properties similar to natural diamond. 🔹 Recognizable by its gold color

🔹 Slightly softer than TiN (~2000 HV) but excels in corrosion resistance and low residual stress. Great for molding plastics, hydraulic components, and food processing equipment. Offers good wear resistance and reduces friction

🔹 Harder and tougher than TiN (up to ~3500 HV), with a darker, charcoal-gray appearance. Ideal for high-speed machining and stamping tools.
