Abstract
The invention relates to an electrode material for a sparking plug. The electrode material comprises the following raw materials in percentage by weight: 20-22 percent of chromium, 10-15 percent of iron, 0.8-1.0 percent of manganese, 0.2-0.5 percent of silicon, 0.1-0.15 percent of titanium, 0.1-0.3 percent of zirconium, 0.03-0.05 percent of boron, 0.003-0.005 percent of cerium, 0.003-0.005 percent of scandium, 0.05-0.08 percent of cobalt, 0.05-0.08 percent of calcium and magnesium, and the balance of nickel. By adopting a Ni-based nickel-chromium-iron alloy ignition device electrode, resistance to high temperature oxidation, vulcanization, corrosion loss as well as stress, deformation and fracture caused by thermal mechanical factors can be enhanced.
Description
Technical field
The invention belongs to metal material field, specifically a kind of engine spark plug electrode material.
Background technology
Spark plug is a kind of spark ignition device, and it extends into the combustion chamber of internal combustion engine and produces spark, with light fluid gas mixture.The newly-developed of engine technique result in higher operating temperature, to obtain higher engine efficiency.
Now being widely used in the electrode material manufacturing spark plug is Ni base nickel-chromium-ferro alloy.When working temperature increases, the pyro-oxidation resistance of these Ni base nickel-chromium-ferro alloys will reduce.Because burning situation is high oxidation, the corrosion losses comprising deformation and fracture caused by high-temperature oxydation and sulfuration can be produced, especially aggravate at the highest operating temperatures.
Therefore, need a kind of high-performance electrode be made up of Ni base nickel-chromium-ferro alloy, it has the performance of the high temperature oxidation resisting of improvement, sulfuration and related corrosive wear, and the High temperature tensile improved, creep rupture and fatigue strength and crack-resistant and fracture property.
Summary of the invention
The object of this invention is to provide a kind of electrode material for spark plug, it has the performance of the high temperature oxidation resisting of improvement, sulfuration and related corrosive wear, and the High temperature tensile improved, creep rupture and fatigue strength and crack-resistant and fracture property.
The present invention is achieved by the following technical solutions:
A kind of spark plug electrode material, include by weight percentage, the scandium of the boron of the titanium of the manganese of the chromium of 20-22%, the iron of 10-15%, 0.8-1.0%, the silicon of 0.2-0.5%, 0.1-0.15%, the zirconium of 0.1-0.3%, 0.03-0.05%, the cerium of 0.003-0.005%, 0.003-0.005%, the cobalt of 0.05-0.08%, the calcium of 0.05-0.08% and magnesium, surplus is nickel.
The invention has the beneficial effects as follows:
Stress, deformation and fracture performance that Ni base nickel-chromium-ferro alloy ignition device electrode of the present invention causes by providing the high temperature oxidation resisting of improvement, sulfuration, corrosion losses and heat resistanceheat resistant machinery, overcome some shortcoming and defect be present in prior art spark plug.
