Study on Performance Improvement of WC-Co Cemented Carbide by TiC/TaC Additive AITranslate
Abstract AITranslate
In order to improve the status quo that the commonly used cutter pick in coal mining engineering is easy to failure due to the damage of the carbide bit,the effects of TiC and TaC additives on the performance of WC-Co cemented carbide bit were studied.The results show that the structural hardness (HRA)of the treated bit can reach 87 ,which is much higher than the national standard of cutter pick of 65.Compared with the interior,the surface fracture toughness of the cutter pick is lower due to the formation of a large number of carbides on the surface,the average fracture toughness is about 15.50 MPa ·m^1/2.The internal fracture toughness is improved due to the presence of a large number of non-carbides,and its average value is 16.31 MPa ·m^1/2.
