“…Recommended fatigue limit for bearing materials for low and medium speed engines are 12-14 MPa for Tin Babbitt, 20-35 MPa for Aluminum and 38 MPa for Copper based bearings. As the temperature of bearing increases from 20 to 160 0 C, the fatigue strength of tin Babbitt decreases to half (Pratt 1973).…”

In the past few years, the need for low-cost, high-performance materials is increasing. Design engineers and researchers are replacing the metals and alloys with advanced materials. Journal bearings are integral parts of machines, engines running to serve the purpose. They play a significant vital role in the performance, efficiency, minimizing the cost of operation, enhancing the durability and reliability of the system. Materials used for these moving elements have undergone tremendous change since the invention of Tin Babbitt. In this paper, a critical review of Journal bearing materials, right from the old-age Babbitt to advanced materials in use till date is presented. Metallurgical aspects and mechanical behavior of successful, widely used bearing materials along with their micro and nanocomposite alternatives are discussed. Tin Babbitt is an ideal material for journal bearing applications. So, it is taken as reference for comparing the quality of other bearing materials.

“…Hule et al [1] includes three basic elements: understand the working atmosphere, designing for proper lubrication and selection of appropriate bearing material for the job. G. C. Pratt [2] reviewed the materials concerned sliding contact bearings which has its own peculiar property requirements. Nano powders production through a rolling-type planetary ball mill apparatus was disclosed by Chen S et al [3].…”

This work highlights an experimental investigation on the surface roughness and hardness of a nano composite, which can replace the liner of a journal bearing. There is a possibility of rotation of bearing liner, due to inconsistent rotation of the journal about its geometrical axis. At the same time, the liner may have sliding action inside the bearing over a period of time. The said drawbacks can be eliminated by replacing the bearing liner by a nano coat. Babbitt is the most widely used material for bearing liner. The Tin of Babbitt alloy has been replaced by cadmium due to its low coat and better mechanical and thermal properties. The results show that, Cadmium is offering better surface roughness and hardness in comparison with the Babbitt.

“…The properties are wear and corrosion resistance as well as high anti-seizure properties [2]. The aluminium alloy that is in sliding contact between the surfaces has embedability, conformability and compatibility properties, which are achieved by adding tin as an alloying element [3]. This is required to resist welding between the sliding surfaces, allow clearance under the heat, pressure and foreign particles that are present in an engine.…”

A feasibility study on different NDT techniques used for testing bond quality in cold roll bonded Al-Sn alloy/steel bimetal strips

-This paper presents non-destructive testing (NDT) results for the detection of bond defects in aluminiumtin (Al-Sn) alloy/steel bimetal strips. Among all types of bimetal strip that are used in the automotive industry for plain journal engine bearings, Al-Sn alloys cold roll bonded (CRB) onto steel backing is the most common type. The difficulty to evaluate the metallurgical bond between the two dissimilar metals is a major industrial concern, which comprises the risk that bearings fail in the field. Considering the harsh performance requirements, 100% online non-destructive testing would be desirable to significantly reduce the business risk. Nowadays bimetal strip manufacturers still rely on destructive testing through different peel-off tests. This work offers the results from four independent NDT studies, using active thermography, shearography, ultrasound and guided wave electromagnetic acoustic transducers (EMATs) and samples with different artificially implanted defects, to explore the feasibility to qualitatively indicate the occurrence of bond defects. A destructive peel off test was used to correlate the NDT results with known bond quality. The studies were done under laboratory conditions, and in case of ultrasound also online under production conditions. During the ultrasound online test, the requirements that a NDT technique has to fulfil for online inspection of Al-Sn alloy/steel bimetal strip were established. For active thermography, shearography and guided wave EMAT techniques, it was theoretically analysed, if the laboratory test results could be transferred to testing under production conditions. As a result, guided waves using EMATs, among the four tested methods, are best suited for online inspection of Al-Sn alloy/steel bimetal strip. This research was carried out in collaboration with MAHLE Engine Systems UK Ltd., an Al-Sn alloy/steel bimetal strip manufacturer for the automotive industry.
