Abstract

PURPOSE:To provide a sufficient corrosion preventive effect in a corrosive environment contg. colorine ions by coating the surfaces of steel materials and structures in contact with corrosive environments by melt-spraying Al of high purity. CONSTITUTION:Al of 99.4-99.7% purity is melt-sprayed on the surfaces of steel materials and structures in environments contg. chlorine ions such as crude oil storage tanks or the like located along the shore, whereby films are formed. The purity of the Al is at least 99.4% and the Al is required to be at least the one of which impurity contents such as Si, Fe, Cu, Ti, Mn or the like that degrades the corrosion resistance of Al are <0.15 Si, <0.2 Fe, <0.01 Cu for the high purity Al wire specified in JIS.
