【Abstract】 On the basis of laboratory working, some coatings with good performance on corrosion resistance in geothermal water have been developed. Further, these coatings have been applied to the geothermal pump shaft and geothermal heat exchangers for corrosion protection. The results show that the service life of the geothermal pump shaft with coating can be prolonged; the geothermal heat exchangers with coatings have good performance on corrosion resistance and heat transfer.更多还原
