In the long term this can lead to corrosion and leaks and if left unchecked will cause more damage fatal. In writing this essay will include studies and research which include visual observation and testing where the results of the test analysis and amendments supported by way of hardness testing, observation metallography with various enlargement as well as chemical composition testing, SEM and EDS to determine the elements - the chemical element and SEM test to determine the microstructure .} }
