摘要： A method of making a spark plug electrode includes several steps. One step includes providing an inner core of a ruthenium (Ru) based alloy or an iridium (Ir) based alloy. Another step includes providing an outer skin over a portion or more of the inner core in order to produce a core and skin assembly. The outer skin can be made of platinum (Pt), gold (Au), silver (Ag), nickel (Ni), or an alloy of one of these. Yet another step includes increasing the temperature of the core and skin assembly. And another step includes hot forming the core and skin assembly at the increased temperature.

摘要： An electrode material that may be used in spark plugs and other ignition devices including industrial plugs, aviation igniters, glow plugs, or any other device that is used to ignite an air/fuel mixture in an engine. In one embodiment, the electrode material is a ruthenium-based material that includes ruthenium (Ru) as the single largest constituent on a wt % basis, and at least one of rhenium (Re) or tungsten (W). The electrode material may further include one or more precious metals and/or rare earth metals. The electrode material may be used to form the center electrode, the ground electrode, firing tips, or other firing tip components.

摘要： An electrode material for use with spark plugs and other ignition devices. The electrode material is a two-phase composite material that includes a matrix component and a dispersed component embedded in the matrix component. In a preferred embodiment, the matrix component is a precious-metal based material and the dispersed component includes a material that exhibits a high melting point and a low work function such as, for example, carbides, nitrides, and/or intermetallics. A process for forming the electrode material into a spark plug electrode is also provided.

摘要： A method of making an electrode material for use in a spark plug and other ignition devices including industrial plugs, aviation igniters, glow plugs, or any other device that is used to ignite an air/fuel mixture in an engine. The electrode material is a ruthenium-based material that includes a “fibrous” grain structure. The disclosed method includes hot-forming a ruthenium-based material into an elongated wire that includes the “fibrous” grain structure while intermittently annealing the ruthenium-based material as needed. The intermittent annealing is performed at a temperature that maintains the “fibrous” grain structure.

摘要： A spark plug suppressor and a method of producing a spark plug suppressor from a suppressor precursor liquid that may be cured at a temperature below 300° C. The spark plug suppressor may include particles or grains dispersed in a matrix of electrically conducting material, electrically semiconducting material, or electrically non-conducting material. The suppressor may include a conductive glass seal component and a resistive suppressor component. The resistive suppressor component may be at least partially embedded in the glass seal component, and the glass seal component may seal a center electrode of the spark plug, a terminal of the spark plug, or both the center electrode and the terminal.
