Magnesium alloys are new class of biodegradable materials usually called as bioresorbable biomaterials for orthopedic applications. The potential benefits of Mg alloys are the nearer modulus of elasticity to the bone than stainless steel or titanium, biocompatibility and bone-active properties and the elimination of necessity of a second operation to remove the implant body. Two- component Mg-Ca alloy is characterized by a solid solution limit, and creates a stable intermetallic phase Mg2Ca. Studied samples were prepared by melting starting material in an induction furnace in a quartz crucible.The micro chemical analysis of samples using a scanning electron microscope with EDS was performed. Values of the microhardness of materials were compared before and after remelting.
