Abstract
Two step laser’s welding of Sm and Fe powders on duralumin substrate in the argon gas flow has been firstly tested. It was established that oxidation of Sm atoms with formation of Sm2O3 and SmO during laser welding of duralumin substrate is the main reason of not forming of the SmFex compound, which can be appeared on the second step of Fe laser welding. The next reason is a strong interaction between Al and Sm atoms at the interface with a substrate with formation of Al2Sm compound, consisting from paramagnetic atoms. So, an additional protection from oxidation needs during laser welding. Magnetic properties of coatings formed by layer-by-layer laser welding from Sm and Fe powders on duralumin AMg-3 substrate welded with and without external magnetic field have been studied by methods of field and temperature magnetization measurements and study by vibromagnetometer method at room temperature (300 K). A strong paramagnetic contribution of AMg-3 substrate has been proved. Al2Sm grains without substrate have shown soft ferromagnetic properties at 300 K independently from using an external magnetic field. An interesting phenomenon has been found at cooling coatings down to 4 K: magnetic ordering of Al2Sm domains with Curie temperature about 70 K.
