Effect Of Cr2o3 And Tin Coatings On 13cr-4ni Turbine Blade Material By Hvof Process: A Review



In this paper, we investigate the effect of Chromium oxide (Cr2O3) and Titanium nitride (TiN) coatings on 13Cr-4Ni turbine blade material by high-velocity oxyfuel (HVOF) process in order to improve its wear characteristic, erosion and corrosion behavior and other mechanical properties. In the present paper studies carried out by various investigators has been discussed. Based on the literature survey various theoretical, and case studies have been discussed with some remedial measures suggested by various investigators. On the basis of several papers we gone through, we are going to compare the above mentioned properties with and without coatings and also find that the coating done by HVOF process can reduce the silt erosion problem in hydro turbine at a certain level.
