摘要
Influence of scanning surface remelting of orthopaedic cast alloys of pseudo-eutectic and eutectic compositions with using continuous laser radiation on these alloys hardness and chemical homogeneity is studied. As shown, the hardness of surface and its homogenization enhance, eliminating principal cause of the galvanic current initiation at denture treatment using the alloy of one composition due to refinement of pseudo-eutectic alloys surface structure and its amorphization in the alloys of eutectic composition.
