“…It was found from previous experiments that good coating layers were produced by setting the atomic ratio of Al to Ti at 4 to 1. 15,16) The Al concentration in sheets was adjusted by dilution with Fe powders. Purity of Al, Ti and Fe powders was 99.9, 99.6 and 99.5 mass%, respectively.…”

“…Recently, Suzuki et al have developed an Al-powder-alloy coating method for pure iron and a carbon steel. 15,16) It is expected that the method enables us to produce good coating layers with controlled Al concentrations by using eutectic reaction in a ternary Al-Ti-Fe system. The purpose of this study is to investigate applicability of the Al-powder-alloy coating method to nuclear systems.…”

A new Al-alloy coating method using Al, Ti and Fe powders has been applied to 316SS in order to develop corrosion resistant coating in liquid lead-bismuth eutectic (LBE). The 316SS plates with coating layers of different Al concentrations were exposed to liquid LBE with controlled oxygen concentrations of 10 À6 to 10 À4 mass% at 823 K for 3600 ks. While surface oxidation and grain boundary corrosion accompanied by liquid LBE penetration are observed in 316SS without Al-alloy coating, the Al-alloy coating is effective to protect such severe corrosion attacks in liquid LBE. Although the coating layer containing 2.8 mass% Al does not always keep sufficient corrosion resistance, good corrosion resistance is obtained through the Al-oxide film formed in liquid LBE in the coating layer where the average Al concentration is 4.2 mass%. Cracks are formed in the coating layer containing 17.8 mass% Al during the coating process. The Al-powder-alloy coating applied to 316SS is promising as a corrosion resistant coating method in liquid LBE environment.

“…However, although titanium is not desirable for hightemperature oxidation resistance, the addition of titanium is necessary to form the Al 3 Ti intermetallic compound and avoid the agglomeration of molten aluminum. 2) A coated layer with 10 mol% titanium exhibited good oxidation resistance at 1073 K. 3) Heating is conducted using a furnace 1) or laser.…”
