Effect of different acidic media on the corrosion behaviour of hardmetals with ...
Pereira, P.; Rocha, A. M. Ferro; Sacramento, J.; Oliveira, F. J.; Malheiros, L. F.; Senos, A. M. R.; Bastos, AlexandreHighly corrosive agents, such as saltwater, hydrogen sulphide, hydrofluoric or hydrochloric acids, are frequently found in oil and gas exploration. The high costs associated with the premature replacement of equipment damaged by corrosion and the consequent production losses justify the search for more resistant materials. In this work, the corrosion behaviour of cemented carbides with different Ni-based binder...
Corrosion resistance of WC hardmetals with different Co and Ni-based binders
Pereira, P.; Rocha, A.M. Ferro; Sacramento, J.; Oliveira, F. J.; Senos, A. M. R.; Malheiros, L. F.; Bastos, AlexandreIn this work, industrially relevant WC composites with alternative binders (Ni, CoNi, NiCr, CoCr, CoNiCr and NiCrMo) were produced and their corrosion resistance in 0.5 M NaCl was compared to conventional WC-Co system. The main objective is to develop hardmetals with higher corrosion resistance to extend the lifetime of tools and equipment, reducing the demand for new parts and maintenance, thus decreasing the ...
