Failure Analysis of Engineering Components
Engineering components such as shafts, crankshafts, axles, bearings, gears, pinions; components of the machines like presses, engines, turbines, motors & generators, earth moving / material handling equipment, construction & mining equipment and similar others are normally designed for an intended service life with a certain factor of safety. Over the past few decades there is a growing trend in engineering industry towards material and cost reduction rather than robust designing of components followed in past. Despite of all due precautions the machines and components fail during service leading to loss of time, money and at times human lives. Likewise, sometimes materials fail during manufacturing stage also. Analyzing the inevitable failures that occur during manufacturing and service is therefore an essential engineering practice for continual improvement in product quality and reliability.
Engineering components have been found to fail due to faulty design, faulty manufacturing practices or due to improper service conditions. In turn there are various types of failures such as overload failures, fatigue failures, wear and fretting failures, corrosion related failures, thermally induced failures and so on.
Investigation of failure of engineering components involves mechanical testing, metallography or microstructural examination, chemical analyses (bulk, local, surface corrosion products, and deposits), X-Ray diffraction studies for phase identification besides host of non-destructive testing techniques like magnetic particle inspection, eddy-current testing, ultrasonic and radiography, etc. TCR has a strong base of facilities to carry out all these investigations along with a team of experts. We have also access to the know-how from certain highly specialized experts from various disciplines whose services and guidance is availed as and when required.
