How does it work?
The beauty of Titanium Nitride Coating lies not just in its exceptional properties, but also in the intricate process through which it is applied. This process ensures the substrate benefits from the robust and protective layer of TiN.
Step 1:Cleaning & Preparatio
Before the coating process begins, it’s essential to prepare the surface. This involves cleaning the component meticulously to ensure there are no residues, contaminants, or oxides. This pristine surface allows for optimal adhesion of the Titanium Nitride layer.
Step 2: Physical Vapor Deposition (PVD)
In a specialized vacuum chamber, titanium and nitrogen are introduced as gases. When subjected to high-energy processes, these gases ionize, turning into a plasma state. The ions from this plasma state then adhere to the component’s surface, forming a solid, thin film of Titanium Nitride.
Step 3: Layer Growth
As the PVD process continues, the TiN layer on the component’s surface grows uniformly. This ensures the entire component is effectively covered, providing a consistent and thorough protective layer.
Step 4:Cool Down & Final Inspection
Once the desired thickness of the Titanium Nitride layer is achieved, the component is cooled down. Post-cooling, a rigorous inspection is carried out to ensure uniformity, adherence, and quality of the coating.
Step 5:Post-Treatment (if necessary)
In certain applications, post-treatment processes might be employed to enhance specific properties of the coated component, such as its smoothness or hardness.
