6 Conclusion
Based upon hardness testing,XRD analysis and microstructural characterization of the weld overlay surfacing,the following can be concluded:
(1) Hardfacing is the most versatile process to improve the life of the worn out component.
(2) Hardfacing can be done on any steel material using wide variety of welding processes.
(3) Different alloying elements can be introduced into the base metal in the form of weld consumables to achieve any desired property like hardness,wear resistance,abrasive resistance,crack resistance etc.
(4) Factors such as welding speed,alloy addition and their interactions play a significant role in the in
hardfacing.
(5) Taguchi’s experimental design strategy was applied to obtain optimum process-parameter combinations for the performance criteria of maximization of hardness.Interestingly,the optimal levels of the factors for the all four electrodes happened to be different.
(6) Mo as alloy addition is not very effective in high Mn hardfacing alloy.
(7) Mo as alloy addition is effective when there is Cr as major alloy in hardfacing alloy.
(8) Refractory metal of Mo,which has been known to be solid solution hardening element also contributes to the strength via precipitation hardening by forming MC andM2C carbides.
The precipitation impedes the movement of dislocations and hence produces hardening
effect in the hardfacing layer; however the role of Mo is varied in different base metal compositions.
(9) It can be concluded that the hardness is affected by the Si addition,Mo addition,by the speed of
deposition and also on the C percentage present in hardfacing alloy.
(10) In case of low Mn steel considering all the process parameters remaining same,maximum manganese obtained in overlay having low Si content decreasesdilution effect.
