Abstract
The invention discloses an alloy material, and concretely relates to an alloy material CuNi9Sn6 of an antifriction alloy layer of connecting rod bushing, which comprises the following raw materials by weight: 7.5-10.5% of Ni, 4.5-7.5% of Sn and balance of Cu, The alloy material does not contain lead, and is environmentally friendly material, while being used on the connecting rod bushing, the hardness is obviously better than that of other same kind of alloy material, and the fatigue resistance performance of the alloy material equals to the traditional lead-containing alloy material.
Description
Technical field
The present invention relates to an alloy material, specifically a kind of alloy material alloy material CuNi9Sn6 of connecting rob bushing antifriction alloy layer.
Background technique
Connecting rob bushing is the important connected element of connecting rod small end and wrist pin, subjects the alternating action of the pressure of explosion of link assembly inertial force and piston transmission, therefore require that sleeve surface needs high hardness in real work.For reaching this hardness requirement, normally powdery metal bell metal sintering is formed wearing layer on steel backing, this metal bell metal was all select CuPb10Sn10 in the past, and lead can improve the antifriction quality of rigid surface.But from environmental angle, use lead, can produce when founding contains the alloy of these toxic metals the toxic gas befouling environment be detrimental to health in a large number.Also product is had to be that the alloy material for bearing shell wearing layer is directly used in lining at present, this alloy material is generally Cu-Ni-Sn system alloy material, continue on this basis to add hardness and the lubricating requirement that a certain or various trace elements reaches bearing shell surface, but this alloy material is owing to will take into account the lubricity on bearing shell surface, therefore often this hard material of Ni adding quantity is few, the soft material adding quantitys such as tin are many, therefore, when this alloy material be used on bearing shell wearing layer is directly used in lining, hardness do not have essence improvement.
Summary of the invention
The present invention aims to provide that a kind of hardness is high, the alloy material be used on connecting rob bushing wearing layer of leadless environment-friendly.
Claimant finds through repetition test, even if same alloy raw material, when adopting special proportioning, different effects can be obtained, such as in hardness or fatigue resistance or corrosion resistance, there is Special Manifestations thus difference Analysis scope, or be used in the parts of the different use needs such as steam turbine, centrifugal compressor or internal-combustion engine.
For composition disclosed by the invention and proportioning, when adopting the alloy material of material composition of the present invention and proportioning to be cast on steel backing plate, this alloy rigidity detects can reach about 110HB through hardness tester, but after to sheet-metal press working integer, alloy-layer increases by force density suddenly through punching press, hardness reaches as high as 170HB, is greatly better than other with the cost even hardness of higher cost alloy material.
Technological scheme of the present invention is achieved in that a kind of alloy material CuNi9Sn6 for connecting rob bushing antifriction alloy layer, makes Ni:7.5 ~ 10.5 % by the raw material of following weight percent meter; Sn:4.5 ~ 7.5 %; Cu surplus.
As optimal way, the alloy material CuNi9Sn6 for connecting rob bushing antifriction alloy layer of the present invention, makes Ni:9 % by the raw material of following weight percent meter; Sn:6 %; Cu surplus.
The invention has the beneficial effects as follows:
1, this product is corrosion-resistant, and owing to there being the lead of high level in conventional alloys, and copper-lead exists as a mixture, and plumbous corrosion-resistant causes final products corrosion-resistant; And material of the present invention exists with alloy form, corrosion resistance is good.
The toxic element such as 2, environmental protection, product of the present invention are completely not leaded, harmless, environmentally safe.
3, hardness is high, be below this product with the hardness ratio of comparative example comparatively
4, material of the present invention is at " sapphire fatigue test board " through Fatigue test, when fatigue resistance reaches 160MP for there is fatigue phenomenon, meets internal-combustion engine usage requirement, can substitute the antifatigue effect of lead-containing alloy.
Embodiment
For an alloy material CuNi9Sn6 for connecting rob bushing antifriction alloy layer, make Ni:9 % by the raw material of following weight percent meter; Sn:6 %; Cu surplus.
Claims (2)
1. an alloy material alloy material CuNi9Sn6 for connecting rob bushing antifriction alloy layer, is characterized in that: make Ni:7.5 ~ 10.5 % by the raw material of following weight percent meter; Sn:4.5 ~ 7.5 %; Cu surplus.
2., by the alloy material alloy material CuNi9Sn6 of a kind of connecting rob bushing antifriction alloy layer described in claim 1, it is characterized in that: make Ni:9 % by the raw material of following weight percent meter; Sn:6 %; Cu surplus.
