TiCN PVD coating is used in different applications as it enhances the properties of the materials and makes them suitable for different environments.
If you are looking forward to learning about the process of TicN PVD coating and its associated benefits and applications, you can go through this guide below.
What is TiCN PVD Coating?
TiCN is a compound made with nitrogen, titanium, and carbon. It creates a ceramic material that is applied in the form of a coating.
The process of PVD vaporizes the titanium in a vacuum chamber so that it reacts with carbon and nitrogen. A thin and hard layer is then created on the surface of the component.
TiCN PVD coating offers hardness and wear resistance, which enhances the life of the components on which it is applied.
This layer even makes the components suitable for applications involving high temperatures and the unique color it has enhances the visual look of the tools that are coated.
General Steps Involved in TiCN PVD Coating
The process of applying TiCN PVD coating involves various steps, and these are given below:
Preparation of Surface
The first stage is where the surface subjected to coating is prepared. The process starts with cleaning the component or tool and wiping off oil, dirt, or any other contaminants.
Cleaning is a crucial stage, as if there is any contaminant, the quality of the coating can be compromised. Some components may need pre-treatments so that the results of coating can be enhanced.
Loading Components in Coating Chamber
After cleaning the components, they are loaded into the PVD coating chamber. The chamber has fixtures that hold the components in a secure way and ensure that the coating is carried out in a uniform way.
The PVD chamber is then evacuated so that a high vacuum environment can be created, which ensures that the coating application offers purity.
Preheating and Ion Bombardment
To enhance the surface of the components for better cleaning, ion bombardment is performed. It ensures that the coating is applied in a better way. The component is also heated to a certain temperature based on the material to be coated.
The step of preheating improves coating adhesion and also reduces the inner stress in the layer of coating.
Application of TiCN PVD Coating
In this stage, where the component is present in the chamber, titanium is added. After vaporizing, it creates plasma. Reactive gasses like carbon and nitrogen are also added to the chamber, and they react with titanium to create TiCN.
The layer of TiCN is then deposited on the component in the form of a thin coat. The process is carried out in a very controlled way to ensure that the thickness and uniformity of the coating is free from flaws.
Cooling of Component
As the process of coating is completed, the coated components are left to cool down so that the adhesion of the coating is attained as needed. Then, the components are removed from the chamber.
If required, some post-treatments may also be applied to the components which are coated with TiCN.
Benefits of TiCN PVD Coating
The benefits of titanium carbon nitride coating include the following:
Durable Tool Life
When the TiCN PVD coating is applied to the machining tools, the life of these tools increases due to the addition of wear resistance and hardness.
Due to the added durability of the tools, the time spent in changing the tools and money spent on replacement is saved.
