Research Progress on Friction and Corrosion Behavior of Mining Cemented Carbide
Cemented carbide is a kind of cement containing hard phase(WC)and soft bonded phase(Fe,Co,Ni,HEA,etc.)and its combination of good friction resistance,high hardness,good hot hardness and other excellent characteristics makes cemented carbide widely used in mines,tunnels,drilling and other geological engineering.Due to the complex actual service environment,cemented carbide in geological engineering applications often faces extremely harsh working conditions,and there are many failure mechanisms,such as friction,corrosion and thermal shock,each of them or a combination will cause the failure of cemented carbide materials.Therefore,understanding the failure mechanism of cemented carbide in geological engineering applications is of great significance for the selection and improvement of cemented carbide materials in different environments.The friction and corrosion behavior of cemented carbide for mining was reviewed,focusing on the influence of environmental and thermal stress on.cemented carbide failure.In addition,due to the important influence of composition on the microstructure and mechanical properties of cemented carbide,the influence of binder phase and additives on the friction and corrosion behavior of cemented carbide was also reviewed.It aims to provide a reference for the selection,improvement and development of new cemented carbide in the future.
