Abstract
The invention discloses a kind of high-performance powder smelting inlet valve seat ring, by weight, it is made up of following raw materials according：C：0.5 1.5 parts, W：27 parts, Cr：28 from, Mo：3 10 parts, V：6 15 parts, Co：0.8 5 parts, Cu：10 20 parts, Mn：0.2 3 parts, Fe：Surplus.Invention additionally discloses its preparation method.High-performance powder smelting inlet valve seat ring prepared by the present invention, with abrasion resistance, can tackle severe engine operating condition；Meanwhile, processing characteristics is improved well, saves the cost of charp tool.
Description
Technical field
The invention discloses a kind of valve retainer and preparation method thereof, and in particular to a kind of high-performance powder smelting suction valve cone
Circle and preparation method thereof.
Background technology
Powder smelting inlet valve seat ring is as an important accessory above engine, and it is mainly used for canned motor
Valve, and all bearing a part of high speed impact all the time substantially.Therefore, powder smelting inlet valve seat ring, should
The very high requirement to meet engine of wearability is asked, has certain processability again with carrying out machine after cylinder cap to add
Work.At present, the material for preparing of the powder smelting inlet valve seat ring of in the market is made or addition conjunction wherein using straight iron powder mostly
The wear-resisting phase of gold, or the powder smelting inlet valve seat ring processability being made up of this traditional material is fine, but wearability is not enough；
Wearability is fine, but very poor in processability.
The content of the invention
It can improve wearability and improve the high-performance powder smelting of its processability again it is an object of the invention to provide a kind of
Valve retainer.
In order to achieve the above object, high-performance powder smelting inlet valve seat ring of the invention, by weight, by following raw materials according
It is made：
C：0.5-1.5 parts, W：2-7 parts, Cr：2-8 is from, Mo：3-10 parts, V：6-15 parts, Co：0.8-5 parts, Cu：10-20 parts, Mn：
0.2-3 parts, Fe：Surplus.
It is another object of the present invention to provide the preparation method of above-mentioned high-performance powder smelting inlet valve seat ring, following step
Suddenly：
A takes the raw material of aforementioned proportion, and is well mixed, and obtains mixed-powder；
The a mixed-powders walked are put into press by b, are pressed, are obtained molded blank；
The b molded blanks walked are put into and high temperature sintering are carried out in sintering furnace by c, while carrying out copper infiltration；
The copper infiltration blank that d walks c, cold treatment is carried out with liquid nitrogen；
The d cold treatment blanks walked are put into heat-treatment furnace by e, are heat-treated；
The e heat treatment blanks walked are machined out by f, are got product.
The beneficial effects of the invention are as follows：Replaced by using instrument comminuted steel shot is the powdered alloy steel containing C, Mo, W, Cr, V, Co etc.
For straight iron powder, the wearability of whole matrix is improved；Meanwhile, addition alloy particle carries out dispersion-strengtherning, and alloy particle is as resistance to
Mill mutually improves wearability；Mn and S can be completely or partially to be added in the new material preparation of the present invention in the form of MnS, and MnS can
Improve processing characteristics as kollag, while the self-lubricating property of material can be improved, improve abrasion environment, improve wear-resisting
Property.
The valve retainer material of the present invention effectively raises the abrasion resistance of powder metallurgy seat ring, can tackle severe
Engine operating condition, while improving processing characteristics well, save the cost of charp tool.
