Babbitt metal,
also called white metal, is an alloy used to provide the bearing surface in a plain bearing. It was invented in 1839 by Isaac Babbitt in Taunton, Massachusetts, USA. The term is used today to describe a series of alloys used as a bearing metal. Babbit metal is characterized by its resistance to gall.
Common compositions for Babbitt alloys:
* 90% tin 10% copper
* 89% tin 7% antimony 4% copper
* 80% lead 15% antimony 5% tin
Originally used as a cast in place bulk ....etc

Metal matrix composite
A metal matrix composite (MMC) is composite material with at least two constituent parts, one being a metal. The other material may be a different metal or another material, such as a ceramic or organic compound. When at least three materials are present, it is called a hybrid composite. An MMC is complementary to a cermet.Contents

The aim of this study is to propose simple and reliable techniques to assess the condition of metal oxide arrester based on the dielectric response techniques. A number of modern electrical diagnostics for Metal Oxide Surge Arrester (MOSA) are discussed in this paper. The techniques included return voltage, decay voltage and polarisation/depolarisation current measurement. The single and multipulse current (8/20micros) was used to artificially degrade the MOSA. The before and after diagnostic ....etc
