There are many effects of tool coating, some of the main effects are described in detail below.

First, improve wear resistance

The coating of the tool can significantly improve its wear resistance, which means that the tool can remain in its original condition for longer, thus reducing the frequency of replacement and repair. The coating protects the cutting edge of the tool and reduces wear, thus increasing the service life of the tool. This not only saves the cost of tool replacement, but also reduces downtime and improves production efficiency.

Second, enhance antioxidant properties

The coating can enhance the oxidation resistance of the tool and prevent the tool from being oxidized during the cutting process. During the cutting process, the tool reacts with oxygen, causing the tool to gradually dull. However, the coating can prevent this oxidation reaction from occurring, thus maintaining the sharpness and durability of the tool. This allows the coating tool to maintain better performance during continuous cutting.

Third, reduce friction

The coating can significantly reduce the friction between the tool and the cutting material. During the cutting process, a lot of heat is generated between the tool and the material, resulting in increased tool wear. However, the coating can reduce this friction, thus reducing heat generation and improving cutting efficiency. This can not only reduce tool wear, but also improve cutting speed and accuracy.

Fourth, improve metal fatigue resistance

The coating protects the cutting edge of the tool and reduces the occurrence of metal fatigue. During continuous cutting, the tool is subjected to repeated stress, which can lead to metal fatigue and fracture. However, the coating can protect the cutting edge of the tool, reduce the occurrence of metal fatigue, and improve the durability of the tool. This allows the coating tool to maintain better performance during a long continuous cutting process.

5. Increase thermal shock resistance

The coating protects the tool from damage at high temperatures. In some applications, such as metal working or cutting in high-temperature environments, the tool is subjected to high temperatures. However, the coating can protect the cutting edge of the tool and the substrate, allowing it to maintain stable performance at high temperatures. This improves tool life and reliability at high temperatures.

Six, improve the cutting edge quality

The coating also improves the quality of the cutting edge. In some cases, the cutting edge may be chipped or damaged, which affects the cutting quality and efficiency. However, the coating protects the cutting edge and reduces the occurrence of chipping and breakage. This improves cutting quality and efficiency and reduces the frequency of changing cutting edges.

7. Improve processing efficiency

Because the coating can reduce friction, improve wear resistance and oxidation resistance and other properties, the use of coated tools can reduce the heat generation and friction resistance during the cutting process, thereby improving the processing efficiency. This can be achieved by increasing cutting speed and reducing downtime. In addition, due to the longer service life of the coated tool, the number of tool changes and downtime can also be reduced, further improving the processing efficiency.

8. Reduce costs

The use of coated tools can reduce costs. Although the cost of coating is relatively high, the use of coated tools can reduce the frequency of tool replacement and maintenance costs. In addition, the coated tool has a longer service life and can maintain stable performance over a longer period of time, thus reducing the total cost. For applications that require high precision and high efficiency cutting, the use of coated tools can bring better economic benefits.

In short, the tool coating has a variety of effects, including improving wear resistance, enhancing oxidation resistance, reducing friction, improving metal fatigue resistance, increasing thermal shock resistance, improving cutting edge quality, improving processing efficiency and reducing costs. These effects can make coated tools show better performance and economy in a variety of applications. Therefore, the use of coated tools is a good choice for applications that require long continuous and efficient cutting.
