Abstract: An electrode material that may be used in spark plugs and other ignition devices for igniting an air/fuel mixture in an engine. The electrode material has a metal ceramic composite structure and includes a particulate component embedded or dispersed within a matrix component such that the electrode material has a multi-phase microstructure. In an exemplary embodiment, the matrix component includes platinum (Pt) and one or more additive metals like nickel (Ni) or palladium (Pd), and the particulate component includes an electrically conductive ceramic, such as titanium diboride (TiB2). A liquid phase or a solid phase sintering process may be used, depending on the particular constituency of the electrode material.

Abstract: 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.

Abstract: 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.

Abstract: A method of manufacturing an electrode material for use in spark plugs and other ignition devices. The electrode material may be manufactured into a desirable form by hot-forming a layered structure that includes a ruthenium-based material core, an iridium-based interlayer disposed over an exterior surface of the ruthenium-based material core, and a nickel-based cladding disposed over an exterior surface of the iridium-based material interlayer. The elongated layered wire produced by the hot-forming then has its nickel-based cladding removed to derive an elongated electrode material wire that includes the ruthenium-based material core encased in the iridium-based material. The elongated electrode material wire can be used to make many different spark plug/ignition device components.
