FAQs About Titanium Nitride(TiN)
What is Titanium Nitride (TiN)?
expand_less expand_moreA:Titanium Nitride is a hard, ceramic coating known for its exceptional wear resistance, high hardness (approximately 80-85 Rockwell C), and distinctive gold color. It is applied to precision components using Physical Vapor Deposition (PVD) to enhance surface properties and longevity.
On which materials can you apply TiN coating?
expand_less expand_moreA:TiN is most commonly and successfully applied to tool steels, stainless steels, and carbide substrates. We evaluate each material’s compatibility and pre-treatment requirements to ensure optimal coating adhesion and performance for your specific component.
How thick is a typical TiN coating?
expand_less expand_moreA:A standard TiN coating ranges from 2 to 5 microns in thickness, ensuring enhanced surface properties without altering part dimensions or tolerances significantly.
What is the maximum operating temperature for TiN-coated parts?
expand_less expand_moreA:TiN-coated components can withstand continuous operation at temperatures up to 600°C (1112°F) without significant degradation, making them ideal for high-heat applications.
Can TiN coating improve tool performance in machining?
expand_less expand_moreA:Absolutely. TiN-coated cutting tools, drills, and end mills exhibit lower friction, reduced material adhesion, higher cutting speeds, and longer tool life—resulting in improved productivity and surface finish.
How does TiN compare to other coatings like TiAlN or CrN?
expand_less expand_moreA:TiN offers excellent general-purpose wear resistance and a low coefficient of friction. TiAlN provides higher heat resistance, while CrN may offer better corrosion resistance in certain environments. Selection depends on application requirements.
