Abstract
The invention relates to an electrode material for a sparking plug. The electrode material comprises the following components 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 provided by the invention, the resistance to high-temperature oxidation, vulcanization and corrosion loss as well as the resistance to strain, deformation and fracture caused by thermal mechanical operation are improved.
Description
Technical field
The invention belongs to metal material field, specifically spark plug electrode material for a kind of engine.
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 has caused higher operating temperature, to obtain higher engine efficiency.
The electrode material that is now widely used in manufacture 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, can produce the corrosion losses that comprise deformation and fracture that caused by high-temperature oxydation and sulfuration, especially aggravation under the highest working temperature.
Therefore, need a kind of high-performance electrode of being made by Ni base nickel-chromium-ferro alloy, it has the performance of improved high temperature oxidation resisting, sulfuration and relevant corrosion losses, and improved high temperature tension force, creep rupture and fatigue strength and cracking resistance 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 improved high temperature oxidation resisting, sulfuration and relevant corrosion losses, and improved high temperature tension force, creep rupture and fatigue strength and cracking resistance 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 chromium of 20-22%, the iron of 10-15%, the manganese of 0.8-1.0%, the titanium of the silicon of 0.2-0.5%, 0.1-0.15%, the boron of the zirconium of 0.1-0.3%, 0.03-0.05%, the scandium of the cerium of 0.003-0.005%, 0.003-0.005%, the calcium of the cobalt of 0.05-0.08%, 0.05-0.08% and magnesium, surplus is nickel.
The invention has the beneficial effects as follows:
Ni base nickel-chromium-ferro alloy igniter electrode of the present invention, by the stress, the deformation and fracture performance that provide improved high temperature oxidation resisting, sulfuration, corrosion losses and heat resistanceheat resistant machinery to cause, has overcome some shortcoming and defect being present in prior art spark plug.
