【摘要】 进行了镧钼丝与纯钼丝作电火花切割电极丝的对比试验。试验结果显示 :在合理控制镧钼丝加工工艺的条件下 ,镧钼丝具有较高的抗拉强度和高温强度 ,其线切割使用寿命明显高于纯钼丝 ,试验数据显示提高 5 0 %左右。实践表明 ,在电火花线切割加工行业 ,用镧钼丝代替纯钼丝作电极丝 ,可有效降低切割成本 ,极具推广应用价值更多还原

【Abstract】 A comparison of Mo La 2O 3 alloy wires and pure molybdenum wires used in eletric spark cutting was made. The results indicate that Mo La 2O 3 alloy wires have higher tensile strength and heat rupture. The service life of Mo La 2O 3 alloy wires is 50 percent more than that of pure molybdenum wires. The Mo La 2O 3 wire improves the quality of surface of workpiece. So it is worth using extensively and the Mo La 2O 3 alloy wires may substitute for pure molybdenum wires in electric spark cutting.更多还原
