Abstract
The influence of corrosion on the strength of a commercial hardmetal and its behaviour under static and cyclic loading has been investigated. Tannic acid was chosen as the corrosive medium in order to simulate the environment to which hardmetal wood-cutting tools are exposed. The results show corrosive attack of unloaded specimens to proceed in a highly localised form, producing defects that reduce the strength of the material by up to 50 %. A further reduction in the maximum endured stress is observed when corrosive attack is combined with a simultaneous static load. This is considered to be due to hydrogen embrittlement. When the hardmetal is subjected to cyclic loading in the presence of the corrosive medium, an increase in the fatigue sensitivity of the material occurs, but noteworthy reductions in lifetime are only observed at low stress amplitudes.
