In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with fig. 1 to 3 are described in detail below.
As shown in fig. 1, an embodiment of the present invention provides a method for forming a babbitt metal bearing, including: s100, processing the Babbitt metal; s200, pressing the Babbitt metal onto the heated steel back to obtain a Babbitt metal bearing; wherein S200 includes: s210, heating the steel back; s220, pressing the Babbitt metal until the Babbitt metal is in complete contact with the steel back; s230, sequentially carrying out pressure maintaining treatment and cooling treatment on the Babbitt metal and the steel back to obtain a Babbitt metal bearing; in S100, the processing treatment is to process the lower end surface of the Babbitt metal to a curvature of 0.00089-0.004.
In the related art, a babbitt metal bearing is generally manufactured by a centrifugal casting method, but for a babbitt metal composite material formed by compounding an emerging babbitt metal with a fiber material or other solid reinforcing phase, a conventional centrifugal casting method is not suitable for manufacturing a composite material containing a solid reinforcing phase in a babbitt metal, because of density difference between the babbitt metal and a solid mixture, and the babbitt metal is melted to cause delamination of the solid reinforcing phase from the molten babbitt metal.
In view of the above, the present invention provides a method for forming a babbitt metal bearing, in which a babbitt metal is pressed against a heated steel backing at room temperature, the babbitt metal rapidly absorbs heat from the surface of the steel backing, the surface layer of the babbitt metal in contact with the steel backing melts, the surface of the steel backing rapidly cools, and a layer of fe—sn intermetallic compound is formed on the surface of the steel backing, thereby improving interfacial bonding strength.
Specifically, the invention presses the Babbitt metal at normal temperature on the heated steel back, and the Babbitt metal at normal temperature rapidly absorbs heat of the surface of the steel back when contacting the surface of the steel back, the surface layer contacted by the Babbitt metal and the steel back is melted, and the bonding surface is in a solid-liquid state in a short time, which is favorable for forming a very thin layer of Fe-Sn intermetallic compound and Cu at the interface 6 Sn 5 Growing on the surface of the steel back, and improving the interface bonding strength between the Babbitt metal and the steel back; the surface of the steel back is rapidly cooled, the crystal structure of the area is not grown up, the crystal grains are fine, and the strength is high; then water is introduced to rapidly cool the steel back, which is beneficial to rapidly preparing the next workpiece and improves the working efficiency; the rapid cooling is beneficial to inhibiting the growth of the crystal structure in the bonding layer region, and achieves the beneficial effects of refined grains and high interface bonding strength.

The structure of the molten liquid ensures that bubbles in the molten liquid are more stressed along the radial direction, and the bubbles are accelerated to be discharged to the periphery. At this time, a solid-liquid-gas interface exists between the steel back and the solid-state Babbitt metal, and along with the continuous downward pressing of the Babbitt metal, the solid-liquid-gas interface continuously moves forward along the radial direction, in this way, bubbles in the Babbitt metal melt are continuously discharged along with the movement of the solid-liquid-gas interface, and finally, no bubbles exist in the bonding area of the Babbitt metal and the steel back, so that the effect of high-strength bonding is achieved.
