INVESTIGATION ON FAILURE OF DTH (DOWN-THE-HOLE) HAMMER BIT
EN 353 grade ferrous material was subjected to forging a DTH bit which was further subjected to heat treatment, upon completion of heat treatment surface cracks observed. An investigation into the occurrence of surface cracks was carried out with the main focus on identifying the reasons either raw material or heat treatment.
Heat Treatment Cycle:
1. Hardening @ 820 ˚ C for 32 hrs
2. Oil Quenching
3. Tempering @ 180˚C for 3 Hrs
4. Oil Quenching
All the inorganic and organic chemicals in the form of solids, liquids can be analysed and identified by using FT-IR instrument. This instrument gives the presence or absence of functional groups that can be identified specifically to the compound in question.
As this instrument is very accurately designed, it is also possible to do the analysis and compare it with the standard compound with known purity. Thus, it becomes an easy job to calculate the percentage of purity of the compound in question. Read More
