Description

Technical Field

[0001] The invention belongs to the technical field of diamond saw blades, and in particular relates to a high-strength diamond saw blade head material. Background Art

[0002] Diamond is the hardest material found in the world and can be used in large quantities in industry, and diamond cutting tools have become an indispensable material for processing various hard materials. Diamond cutting tools are made by mixing metal powder and artificial diamond particles, pressing and sintering. Moreover, with the continuous development of society, the scale of infrastructure construction continues to expand, which also provides a broader application market for diamond tools. Among diamond cutting tools, diamond saw blades have the widest range of use. Diamond saw blades have been widely used in the cutting and processing of marble, granite, concrete, asphalt, ceramics, glass, jewelry, jade, semiconductors and other materials. With the continuous development of technology, the requirements for cutting efficiency and cutting strength are getting higher and higher.

[0003] At present, the diamond saw blade segment is added with strong materials such as W, WC, and W2C, but the wettability with the matrix metal is poor and difficult to sinter, which leads to insufficient holding force of the matrix on W, WC, etc., and easy to fall off during use, greatly shortening the life of the saw blade. At the same time, the amount of wear-resistant phases such as WC and W added in traditional diamond circular saw blades is difficult to exceed 60%, because with the increase of the amount of W, WC, etc. added, the density of the segment sintering decreases, the density of the segment decreases, the hardness and brittleness of the segment increases, and the strength decreases, which is easy to cause serious consequences such as tooth breakage during the cutting process. Therefore, it is necessary to further improve the material of the diamond saw blade segment. Summary of the invention
