The invention belongs to material engineering fields, are related to one kind and are injected into moulding mixture, and in particular to a kind of spark-plug side electrode is with being injected into moulding mixture.A kind of spark-plug side electrode includes: Cr 0.1-1%, Al 0.1-1%, Nb 0.1-1%, Mo 0.1-1%, Ce 0.01-0.5%, surplus Ni with moulding mixture, including metal charge, metal charge is injected by mass.For a kind of spark-plug side electrode disclosed by the invention with moulding mixture is injected into, the sintered density after the material injection molding can reach 99% theoretical density, and the resistance to electric spark ablation of sintered product is substantially better than general copper alloy electrode material.
Description
Technical field
The invention belongs to material engineering fields, are related to one kind and are injected into moulding mixture, and in particular to a kind of spark-plug side electrode use
It is injected into moulding mixture.
Background technique
The effect of spark plug is that the high-voltage electricity for generating ignition coil is introduced into the combustion chamber of generator, in its electric grade gap
Middle formation electric spark, lights the mixed gas of compression, makes engine operation.
Spark plug is mainly made of wiring nut, insulator, wiring screw rod, central electrode, lateral electrode and shell, side electricity
It welds on the shell pole.The electric grade of spark plug is the most important component part of spark plug, is main supporting body when electric arc occurs,
Operating condition is extremely severe, it subjects the strong corrosion of hyperbar, high voltage, the effect of high temperature and combustion product, therefore
Requirement to spark plug material is also relatively high.
But there is following problems for spark plug currently on the market: with the increase of spark plug electricity grade ignition energy, fire
The flower plug easy ablation of lateral electrode.
Summary of the invention
Goal of the invention: the present invention has made improvements in view of the above-mentioned problems of the prior art, i.e., the invention discloses one kind
Spark-plug side electrode is with being injected into moulding mixture.
Technical solution: a kind of spark-plug side electrode includes: by mass with moulding mixture, including metal charge, metal charge is injected into
Cr 0.1-1%, Al 0.1-1%, Nb 0.1-1%, Mo 0.1-1%, Ce 0.01-0.5%, surplus Ni.
A kind of spark-plug side electrode includes: Cr 0.5% with moulding mixture, including metal charge, metal charge is injected by mass,
Al 0.5%, Nb 0.5%, Mo 0.5%, Ce 0.25%, surplus Ni.
It further, further include binder, binder forms mixture after mixing with metal charge, binder accounts for mixture matter
The 7~11% of amount.
Further, binder is the mixture of polyformaldehyde and polyethylene, in which: polyethylene accounts for the 10 of mixture weight
~20%, surplus is polyformaldehyde.
A kind of spark-plug side electrode disclosed by the invention is with being injected into moulding mixture, the sintered density after the material injection molding
99% theoretical density can be reached, the resistance to electric spark ablation of sintered product is substantially better than general copper alloy electrode material
Material.
