Titanium Nitride Laser Cleaning
We've found that the biggest hurdle with titanium nitride in high-wear scenarios comes from everyday abrasion and exposure to harsh conditions, yet its standout hardness and corrosion resistance deliver lasting protection for tools and components without compromising performance.

Titanium Nitride surface magnification
Before Treatment
I've seen contaminated Titanium Nitride surfaces up close at high magnification, and they always show thick layers of grime clinging tightly to the base. Dark spots and irregular clumps cover everything, making the whole area look dull and uneven under the lens. Scratches from handling add rough edges that hide the material's true form.
After Treatment
After laser treatment, the same surface transforms into a clear, even field with no trace of those clinging residues. Fine, uniform patterns emerge across the view, giving a
Titanium Nitride Laser Cleaning Laser Cleaning FAQs
Q: How can I avoid damaging Titanium Nitride coatings during laser cleaning?
A: When laser cleaning Titanium Nitride, you'll want to start with lower power settings compared to softer metals like aluminum, since this hard ceramic coating resists heat better but can crack under sudden thermal shock. Make sure you use short pulses to gently remove contaminants without stressing the surface, and always test on a small area first to check for any unwanted changes in the gold-like finish. Watch out for overheating in the middle of the process, as it might weaken the bond to the substrate, so keep the beam moving steadily across the area.
Q: What settings work best for cleaning Titanium Nitride on tools?
A: If you're cleaning Titanium Nitride on cutting tools, begin with a focused beam to target dirt and residue precisely, unlike with reflective metals where energy scatters more easily. You must adjust the wavelength to one that absorbs well into this durable coating, ensuring efficient removal without abrading the tough layer beneath. This approach brings
