Abstract
The composite board for sintering high-phosphorus tin bronze is characterized by comprising a low-carbon steel plate layer positioned at the lowest layer, a low-phosphorus tin bronze layer positioned above the low-carbon steel plate layer and a high-phosphorus tin bronze layer positioned at the uppermost layer. The low-phosphorus tin bronze layer is sintered tin bronze with the phosphorus content of less than or equal to 0.1%. The high-phosphorus tin bronze layer is sintered tin bronze with the phosphorus content of more than 0.1%. The high-phosphorus tin bronze has excellent wear resistance, but is difficult to sinter with a low-carbon steel plate due to high phosphorus content. The utility model provides a composite board for sintering high-phosphorus tin bronze, which is characterized in that a layer of low-phosphorus tin bronze powder is sintered at first to serve as a transition layer, so that the binding force between the high-phosphorus tin bronze and a low-carbon steel plate is increased, the wear resistance is good, the price is low compared with that of a pure copper shaft sleeve, and the composite board has wide application value in the fields of vehicles, mechanical equipment and the like.
Description
Technical Field
The utility model relates to a bimetal composite sintered plate, in particular to a composite plate for sintering high-phosphorus tin bronze.
Background
The metal sliding bearing is generally made by rolling metal or metal composite plates, is an important part for manufacturing a rotating structure, has the performances of high bearing, impact resistance, wear resistance and the like, and is widely applied to the fields of vehicles, ships, engineering machinery and the like. Besides the copper alloy sleeve, a layer of wear-resistant tin bronze alloy bimetallic plate is sintered or cast on a low-carbon steel plate, and a functional layer of the plate has good wear resistance, a supporting layer has strong impact resistance and has strong price advantage. However, the surface of the mild steel plate is generally sintered with a layer of low-phosphorous tin bronze, and when the phosphorous content is more than 0.1%, the copper powder cannot be sintered on the mild steel plate, and the interlayer bonding strength is poor. Some nickel-containing high-phosphorus tin bronze powders have excellent load-bearing and wear-resistant properties, but cannot be used in bimetallic form as sliding bearings. Therefore, the composite board for sintering the high-phosphorus tin bronze provided by the utility model has the advantages that the low-phosphorus tin bronze powder is sintered at first to serve as the transition layer, the binding force between the high-phosphorus tin bronze and the low-carbon steel plate is increased, the wear resistance is good, the price is low compared with that of a pure high-phosphorus tin bronze shaft sleeve, and the application value is wide.
Disclosure of Invention
The utility model aims to provide a composite board for sintering high-phosphorus tin bronze, which has the advantages of good interlayer bonding strength, strong wear resistance, low price and the like.
The technical scheme of the structure of the utility model is as follows: the composite board for sintering high-phosphorus tin bronze is characterized by comprising a low-carbon steel plate layer positioned at the lowest layer, a low-phosphorus tin bronze layer positioned above the low-carbon steel plate layer and a high-phosphorus tin bronze layer positioned at the uppermost layer.
The low-phosphorus tin bronze layer is sintered tin bronze with the phosphorus content of less than or equal to 0.1%.
The high-phosphorus tin bronze layer is sintered tin bronze with the phosphorus content of more than 0.1%.
The utility model has the following beneficial effects:
1. the bearing capacity is strong, and the wear resistance is good;
2. the bonding strength between the plate layers is high, and the price is low.

Detailed Description
The utility model is further described with reference to the following figures and specific embodiments.
As shown in fig. 1, a layer of low-phosphorus tin bronze powder is uniformly laid on a low-carbon steel plate layer 1, then sintering is carried out at 900 ℃ in a nitrogen-hydrogen mixed gas atmosphere, and after cooling, rolling is carried out to obtain a compact low-phosphorus tin bronze layer 2. And then uniformly paving a layer of high-phosphorus tin bronze powder on the low-phosphorus tin bronze layer 2, sintering at 900 ℃ in a nitrogen-hydrogen mixed gas atmosphere, and rolling after cooling to obtain a compact high-phosphorus tin bronze layer 3. The composite board sintered with the high-phosphorus-tin bronze has the advantages of high bonding force between the high-phosphorus-tin bronze and the low-carbon steel plate, good wear resistance, low price compared with a pure high-phosphorus-tin bronze shaft sleeve, and wide application value.
