IGNITION DEVICE ELECTRODE COMPOSITION |
摘要 |
<p>An ignition device includes a ground electrode, center electrode, or both composed of a cobalt based alloy including: Ni in an amount between about 20 and 24% by weight; Cr in an amount between about 20 and 24% by weight; W in an amount between about 10 and 16% by weight; and Co in an amount between about 32 and 47% by weight or alternately an iron-based alloy comprising: Cr in an amount between about 18 and 24% by weight; Al in an amount between about 4 and 7% by weight; and Fe in an amount between about 67 and 78% by weight. It is believed that the electrode alloys may also include Zr and B in an amount, by weight, of 0.005-0.5% Zr and 0.001-0.10% B. Center or ground electrodes of the invention may also include firing tips attached at a sparking end thereof. The firing tips may be formed of at least one of gold, a gold alloy, a platinum group metal or a tungsten alloy.</p> |
