Study on Tungsten Carbide Leaching of Cemented Carbide Tool in Sodium Carbonate Solution
In the cutting progress, the cutting temperature and the friction will be reduced when the water-based cutting fluid is used, but some elements in the cutting fluid will result in the leaching of tungsten carbide in cemented carbide tool. The influence rule of sodium carbonate on the tungsten carbide leaching of cemented carbide under the condition of different temperatures and different concentrations is investigated by soaking experiments, SEM analysis, energy spectrum analysis and electrochemical detection experiments. The experimental results reveal that the influence of sodium carbonate on the tungsten carbide leaching are great, and the leaching rate will increase with the increasing of temperature and concentration.
