MATERIAL FOR SPARK PLUG ELECTRODE HAVING EXCELLENT SPARK WEAR RESISTANCE AND DISCHARGE PROPERTIES
摘要：
A material for a plug electrode having not only excellent oxidation wear resistance but also excellent spark wear, and also having adequately-considered discharge properties in use is provided. The present invention relates to a material for a plug electrode, comprising 5% by mass or more and 30% by mass or less of Cu, 0.1% by mass or more and 15% by mass or less of Ir, with the balance being Pt. Alloying by combining two metals of Cu and Ir can reduce discharge voltages and improve durability against spark wear. With addition of only one of them, the effect of improving spark wear properties is poor and the effect of reducing discharge voltages cannot be expected.
摘要（中）：

提供了一种用于插头电极的材料，其具有不仅优异的耐氧化耐磨性，而且具有优异的火花磨损，并且在使用中也具有充分考虑的放电特性。 本发明涉及一种用于插头电极的材料，其包含5质量％以上且30质量％以下的Cu，0.1质量％以上且15质量％以下的Ir，余量为Pt 。 通过组合Cu和Ir的两种金属合金可以降低放电电压并提高耐火花磨损的耐久性。 仅添加其中之一，改善火花磨损性能的效果差，并且不能期待降低放电电压的效果。
