The quantitative lead was added into the sample solution to let the concentration come up to be in the interval range suitable for determining by the spectrophotometry of arsenazo Ⅲ, which was used to determine lead in the Babbitt alloy.

Babbitt alloy is difficult to adapt higher temperature due to its low softening point.

The thorough analysis was made on adhesive failure and cracking in the surface of Babbitt bush.

The micro-structure and preparing processes of modified Babbitt alloy were designed by axiom de- sign theory.

A simulative bearing tester was employed to investigate the in situ generation of self-reconditioning layer on worn 45~# steel surface rubbed against Babbit alloy under designed tribological conditions,and its tribological behaviors.

The chemical composition analysis,the metallurgical structure analysis,The XRD analysis and the X-ray energy spectrum analysis were accomplished for the peeled babbit alloy.

A thrust bearing bush with elastically metallic plastics as a substitute for babbit alloy was used for the structure imrovement in the main motor.

Pouring of the axle tile babbit layer and the craft of processing;

The paper analyses influcing babbit joining force factors on problem that babbit often comes unstunk in babbit bearing manuiacture,and proposed improving actions which have led to great improvement.

The babbit bearing bush supporting the joint shaft damages frequently.

The paper carries on the research proof in view of theflaws by Babbitt metal tradition welding process of the rolling mill three header axle bush,formulates the reasonable welding process finally.
