What effect does the particle size of iron-based alloy powder have on diamond ceramic saw blades?
Most of Sagwell'salloy powderproducts are iron-based Alloy Powders. Many customers who make diamond ceramic cutting blades will ask about the particle size when using our powder as the matrix material. Today we will talk about the problem of powder particle size, especially the impact of "ultrafine" powder particle size on the matrix.
First of all, it is certain that the particle size of the iron-based alloy powder does have an impact on the performance of the diamond ceramic cutting blade. This impact is mainly reflected in the following aspects:
1. Impact on the sharpness of cutting blades
The particle size of iron-based alloy powder affects the sharpness of the saw blade. Alloy powder with smaller particle size can provide more contact points and a tighter stacking arrangement, thereby enhancing the ability to wrap diamond particles and improving the sharpness of the saw blade. At the same time, fine particles can also reduce the sensitivity of fatigue crack initiation and expansion, increase fatigue life, and indirectly improve the sharpness and service life of the saw blade.
2. Impact on cutting efficiency
The particle size of the iron-based alloy powder will also affect the cutting efficiency of the ceramic cutting disc. Generally speaking, alloy powder with a moderate particle size can better fill the gaps between diamond particles, increase the density and hardness of the cutting disc, and thus improve the cutting efficiency. In addition, iron-based alloy powder with a uniform particle size distribution can also reduce internal defects, improve the overall performance of the cutting disc, and further improve the cutting efficiency.
3. Impact on the strength of the cutting disc
The particle size of the iron-based alloy powder also has a certain influence on the strength of the cutting blade. The fine iron-based alloy powder particles can form a denser structure and improve the hardness and strength of the material. At the same time, the iron-based alloy powder with a narrow particle size distribution can also reduce internal defects and improve the fracture toughness and fatigue resistance of the cutting blade.
4. Impact on the wear resistance of cutting discs
The particle size of the iron-based alloy powder also affects the wear resistance of the blade. Alloy powders with smaller particle sizes can provide more high-energy grain boundaries, promote atomic diffusion and solid phase sintering, and thus improve the density and wear resistance of the blade. In addition, the fine iron-based alloy powder particles can also act as an obstacle to crack propagation, slowing down the crack propagation speed and improving the fracture resistance of the blade.
In summary, the particle size of the iron-based alloy powder has an important influence on the performance of the diamond ceramic cutting blade. Therefore, when preparing the cutting blade, it is necessary to select the iron-based alloy powder with the appropriate particle size according to the specific application requirements and process conditions to obtain the best cutting effect and service life.
