Definitions
- This invention relates to engine components, and more particularly to engine components having greatly superior wearability.
- Element Percent by weight Total carbon 3.00-3.60 Silicon 2.00-3.00 Manganese 0.70-1.25 Phosphorous a 0.20 max. Sulfur a 0.10 max. Nickel 0.15-0.70 Chromium 0.40-l.25 Molybdenum 0 -070 Titanium 0 10-100 Tungsten O.50-l0.0 Iron Balance Impurity.
- the controlled percentages of titanium and tungsten are essential to the composition. It is by carefully controlling the composition to this range that the surprisingly high wearability results.
- Element Percent by weight Total carbon 3.50 Silicon 2.42 Manganese 0.82 Phosphorous a 0.09 Sulfur a 0.03 Nickel 0.21 Chromium 0.72 Molybdenum 0.34 Titanium 0.19 Tungsten 3.20 Iron Balance Impurity.
- the complete engine component e.g. tappet, camshaft, rocker arm, or other
- the complete engine component is formed of the novel alloy, but at least the bearing surfaces thereof are of the novel alloy.
- the components may be cast by normal casting techniques wherein the material is melted by any standard melting method, then poured into suitable molds, such as sand molds, shell molds, carbon dioxide molds, or permanent molds, with or without chill plates as of carbon. It may be hardened by normal heat training techniques such as those conventionally used on hardenable iron for such components, a typical heat treatment including heating to 1575 F., holding forthirty minutes, then quenching in oil. It is conceivable that minor variations may be made within the concept presented, with the invent-ion being limited only by the scope of the appended claims and the reasonable equivalents thereto.
- An internal combustion engine component comprising a body having at least a bearing surface of a hardenable ferrous alloy consisting essentially of the following composition:
- the component of claim 1 being a tappet.
