Abstract
The invention relates to a high strength bushing, belonging to the engine bushing of the automotive vehicle, which is characterized in that the antifriction layer of the high strength bushing is the quinary alloy layer of lead, tin, copper and indium (PbSnCuIn)+nanometer diamond material. Because the high strength bushing adopts the nanometer alloy, the fatigue resistance of the antifriction layer can be above 120 MPa; the antifriction layer of the prior bushing adopts the ternary alloy of lead, tin and copper, and the fatigue resistance is only about 63 MPa. By adopting the nanometer alloy, the fatigue resistance of the antifriction layer is greatly improved, thus, the fatigue resistance of the bushing can be greatly enhanced.
Description
Technical field
The present invention relates to the motor car engine bearing shell, refer more particularly to high-strength bearing liner.
Background technique
Bearing shell has good bearing capacity and fatigue resistance, has good seizure resistance, embedding Tibetan property, compliance, corrosion resistance and compressive strength simultaneously.Along with diesel engine at a high speed, carry direction by force and develop, a kind of alloy bearing shell obtains use more and more widely, this kind alloy bearing shell comprises base layer, nickel-barrier layer and the anti-attrition layer composition of steel back layer, copper base alloy on structural type, wherein base layer is arranged on the steel back layer, nickel-barrier layer is plated on the base layer, anti-attrition layer is plated on the nickel-barrier layer, and anti-attrition layer generally adopts slicker solder copper (PbSnCu) ternary-alloy material to make.This bearing shell can satisfy the basic demand of motor on a kind of degree, but is applied on the reinforcement internal-combustion engine of Motor Vehicle, because the fatigue resistance of anti-attrition layer is lower, the fatigue resistance of bearing shell, corrosion resistance and wear resistance all have much room for improvement.And along with rapid development of automobile industry, motor has proposed the increase load, has improved requirements such as rotating speed, light in structureization bearing shell, therefore also must propose higher requirement to the coating of bearing shell, this just presses for develops a kind of high-strength bearing liner that corrosion resistance is good, wear resistance is good, fatigue resistance is high that has.
Summary of the invention
The objective of the invention is to: a kind of high-strength bearing liner that corrosion resistance is good, wear resistance is good, fatigue resistance is high that has is provided.
Technical solution of the present invention is: high-strength bearing liner comprises the base layer that steel back layer and copper base alloy are made, described base layer is arranged on the steel back layer, plate one deck nickel-barrier layer on the base layer, electroplate one deck Nanoalloy anti-attrition layer on the nickel-barrier layer, the material of described anti-attrition layer adopts Pb-Sn-Cu-In (PbSnCuIn)+Nano diamond material.
Advantage of the present invention is that the anti-attrition layer of high-strength bearing liner adopts the Nanoalloy material, by adopting the Nanoalloy material, the fatigue resistance of anti-attrition layer of the present invention is improved, the fatigue resistance of anti-attrition layer is up to (adopt sapphire fatigue test board test) more than the 120MPa, thereby improved the fatigue resistance of bearing shell greatly.And the anti-attrition layer of existing bearing shell adopts slicker solder copper ternary alloy, and its fatigue resistance (adopts the test of sapphire fatigue test board) about 63MPa.
Description of drawings
Fig. 1 is an organigram of the present invention.
Among the figure: 1-steel back layer, 2---base layer, 3---nickel-barrier layer, 4---anti-attrition layer
Embodiment
According to shown in Figure 1, the base layer 2 that high-strength bearing liner of the present invention is made by steel back layer 1, copper base alloy, nickel-barrier layer 3 and anti-attrition layer 4 are formed.Described base layer 2 processing plate one deck nickel-barrier layer 3 on the base layer 2 on steel back layer 1, electroplate one deck Nanoalloy anti-attrition layer 4 on the nickel-barrier layer 3.The material of described anti-attrition layer 4 adopts Pb-Sn-Cu-In (PbSnCuIn)+Nano diamond quinary alloy material.
Copper base alloy can or be sintered on the steel back layer 1 by casting as base layer 2.
The performance of the present invention and comparative example compares:
| The present invention | Comparative example | |
| The steel back layer material | Steel | |
| Base layer material | Copper base alloy | |
| The nickel-barrier layer material | Nickel | |
| The anti-attrition layer material | Pb-Sn-Cu-In (PbSnCuIn)+Nano diamond material | Slicker solder copper (PbSnCu) |
| The fatigue resistance of anti-attrition layer material (MPa) | More than 120 | 63 |
| The fatigue resistance of bearing shell (MPa) | Good | Difference |
| The corrosion resistance of bearing shell | Good | Difference |
| The wearability of bearing shell | Good | Difference |
The fatigue resistance of anti-attrition layer material adopts " sapphire fatigue test board " test in the last table.The quinary alloy of Pb-Sn-Cu-In (PbSnCuIn)+Nano diamond material is as anti-attrition layer material of the present invention, and when fatigue resistance was tested at 120MPa, product was normal.
Corrosion resistance adopts " medicinal white oils " test in the table, the corrosion resistance of Nanoalloy anti-attrition layer material of the present invention is than the good corrosion resistance of the ternary alloy anti-attrition layer material of comparative example bearing shell, thereby the corrosion resistance of bearing shell of the present invention is than the good corrosion resistance of comparative example bearing shell.
Wearability adopts " wear testing machine " contrast test.
