Frequently Asked Questions
What is TiN coating?
How is TiN coating applied?
How hard is TiN coating?
How thick is TiN coating?
Surface Solutions tries to apply about .0002” of coating to most parts since this thickness can provide double the tool life, or more, compared to .0001” thick coatings.
Can TiN coating be removed?
Removing TiN from some materials (carbide, titanium, etc.) is not advised because the hydrogen peroxide can chemically attack the substrate material (leaching cobalt from the carbide, etc.).
How much does TiN coating cost?
TiN coating is done in batches, so the price is primarily dependent on how many parts or tools can be coated in one batch. Size of the vacuum chamber, type of part fixturing required (part spacing), part cleaning requirements, and coating thickness are just some of the factors used in determining the price.
In general, commodity type parts (cutting tools, drills, taps, end mills, etc.) have lower coating prices than one of a kind type parts like punches and dies, injection molds, etc. Also, the higher performance coatings cost more than TiN. Here’s our pricing for coating cutting tools. (link to PDF)
