Outline of Final Research Achievements

The present study was undertaken in order to develop of a novel desalination method, which is more effective and safety for iron artifacts, by means of water vapor and diffusion. In order to evaluate optimal condition in the process of deliquescence of ferrous chloride and effectiveness of a novel method for inhibiting corrosion during and after treatment, a series of laboratorial experiments which used samples simulated salt containing iron artifact were conducted. As the results of experiment, corrosion rate of during the treatment was suppressed to approximately 1/2 in comparison with conventional method. In respect of corrosion inhibiting of after treatment, novel method showed equal effectiveness with conventional method. Present results provide effectiveness of novel method.
