Claims15
A method of producing an electrode support for a spark plug, comprising:
- providing the electrode support;
- and
- brazing a portion of an outer surface of a chip to a center portion of the electrode support and another portion of the chip to a side portion of the electrode support, wherein the center portion of the electrode support is formed of a material having the same coefficient of thermal expansion as the chip.
A method of producing an electrode support for a spark plug, comprising:
- providing the electrode support, the electrode support having a center portion and a side portion;
- brazing a chip to both the center portion and the side portion of the electrode support, wherein the center portion of the electrode support is formed of a material having the same coefficient of thermal expansion as the chip;
- and
- removing a section of an electrode material from the chip to create a spark gap.
