| Description |
— Industries in India play an important role in the
economic growth of country. These industries face challenging
conditions in effective corrosion estimation, prevention and
control. The corrosion cost in any developing country is
predicted by 5% of the GDP which is significant to all countries.
In this paper brief information about corrosion and its types hasbeen given. The effects of corrosion in our daily lives are both direct where corrosion affects the useful service lives of our
possessions, and indirect where in producers and suppliers of
goods and services incur corrosion costs, which they pass on to
consumers. Corrosion poses a serious threat to mining industries
as well. Wire rope which is an intricate device made up of a
number of precise moving parts used in underground mines. The
amount of corroded metal is a function of the surface which
oxygen can attack. Steel wire ropes have an exposed surface
about 16 times larger than a steel bar of the same diameter and
will therefore corrode correspondingly faster. Here in this
paper, how corrosion can seriously shorten wire rope life, both
by metal loss and by formation of corrosion pits in the wires has
been described. Static ropes (suspension ropes or rope sections
lying over a saddle or an equalizer sheave) are more likely to
corrode faster than running ropes/ winding ropes. This has been
illustrated with failure analysis of two different types of wireropes used in coal mines, one guide rope which is static in natureand one winding rope which is a moving rope. From the two casestudies it is found that the static guide rope used in coal mineshas been failed due to excessive corrosion resulted in highreduction in diameter.
