        Improvement of Bucket Tooth Design Material

        In the anti-wear measures of bucket teeth of large excavators, corresponding changes and breakthroughs can be made in material selection. Because excavators have to adapt to the mining needs of mines, the material of bucket teeth requires high hardness and strong wear resistance. Therefore, the material itself should have good toughness.

         

        In the design process of bucket teeth, the relative slippage of bucket teeth surface should be kept as fast as possible, and the material should also have high strength performance. In process design, two kinds of composite materials are usually used to modify the properties of materials. Using high manganese steel and alloy steel to compound can greatly ensure the hardness and toughness of bucket teeth, improve the wear resistance of materials, and increase the service life of excavators.
