The composition of iron wire is that C, Si, Mn increase the mechanical property raising that is beneficial to alloy; Too much weaken the wear-resisting of alloy.
The increase of wire volume percent is beneficial to the raising of material wear-resistant.But too much, the magnesium alloy substrate bag does not live copper wire and nitriding iron wire, and crackle appears in matrix, has then reduced the wear-resisting of material.Therefore influence the resistance to corrosion of alloy.
Wire diameter is too thin, and surface-area is too big, is unfavorable for that the coating element dissolves in the magnesium water.Wire diameter is too thick, and the density that distributes in magnesium alloy substrate reduces, and is unfavorable for the attrition resistant raising of material monolithic.
