Abstract:

A surface layer enriched with zinc was formed on magnesium by heating specimens painted with a paste containing ZnCl2+KCl at 440 degrees C for 120 min using no protective atmosphere. The study focused on the microstructure, phase constitution and microhardness of the alloyed layer. The layer, which was about 200 mu m in thickness, had a microstructure composed of a eutectoid mixture (an MgZn intermetallic phase + a solid solution of zinc in magnesium) and some dendrites (a solid solution of zinc in magnesium). At the interface between the alloyed layer and the magnesium substrate, there was a zone of a solid solution of zinc in magnesium. The thermochemical process increased the hardness of the specimens at the surface from 30 HV 0.1 (Mg) to 110-164 HV 0.1 (the layer containing the MgZn intermetallic phase).
