Generally speaking, improving the wear resistance of carbide\u00a0leads to a decrease in carbide\u00a0toughness, and increasing the toughness of carbides results in decreased wear resistance. Wear resistance and toughness are a contradictory unity. How to resolve this contradiction has become a major challenge in today’s carbide\u00a0production. Through test, we have found that adding trace rare earth elements to mining\u00a0carbide\u00a0can effectively address this issue.<\/p>\n

1Dynamic thermal simulation tests were conducted to simulate the changes in carbide\u00a0performance under operating conditions and to determine the influence of rare earth elements on the carbide’s performance.<\/p>\n

2Field trials were carried out at mining production sites to assess the carbide’s service life. We conducted high-temperature dynamic thermal simulation tests at Central South University in China (as shown in Table 2).<\/p>\n

 <\/p>\n

The test results indicate that adding rare earth elements to the carbide\u00a0reduces the carbide’s thermal strength while increasing its thermal plasticity and high-temperature toughness (represented by the total area under the stress-strain curve). This effect is similar to the increase in Co content. carbides containing rare earth elements exhibit excellent thermal plasticity and toughness, allowing them to better accommodate the complex thermal stress plastic deformation differences in high-temperature environments. Therefore, carbides with rare earth element additions can improve their performance in use, enhance wear resistance, and extend their service life.<\/p>\n

The Lugu Iron Mine is one of the locations in China known for having the hardest rocks. Typically, drilling bits with carbide\u00a0insert thicknesses of 16mm are used for ore extraction in this region, while the carbide\u00a0inserts we used in our test were 10mm thick. However, during the entire experiment, no instances of carbide\u00a0fracture were observed with the rare earth element-added carbide\u00a0inserts. The service life of these inserts was also significantly extended compared to the inserts without rare earth elements. This strongly supports the conclusion that the addition of rare earth elements can indeed enhance the carbide’s flexural strength and impact toughness, improving its performance in real-world applications.<\/p>\n
