For process analysis, take two samples from the front and rear working faces respectively, and grind them for hardness test. It is found that the hardness of the same sample varies greatly, and the preliminary judgment is that the material is uneven. The samples were ground, polished and corroded. It was found that there were obvious boundaries on each sample, but the boundaries were different. From the macro view, the surrounding is light gray, and the middle part is dark, which indies that the part is likely to be an inlay casting. From the surface, the enclosed part should also be an inlay. Hardness tests were carried out on both sides of the boundary on HRS-150 digital Rockwell hardness tester and MHV-2000 digital micro hardness tester, and obvious differences were found (see Table 1). Through the above analysis, it is confirmed that the bucket tooth is an insert structure. The closed part is the insert, and the surrounding part is the base. The compositions of the two are similar. The alloying is carried out with Cr, Mn, Si and other elements. The main alloy compositions (mass fraction,%) are 0.38C, 0.91Cr, 0.83Mn, 0.92Si. The mechanical properties of metal materials depend on their composition and heat treatment process. The components are similar but the hardness is different, which indies that the bucket teeth are put into use without heat treatment after casting. The following organizational observation also proves this point.
