title: An innovative spraying setup to obtain uniform salt(s) mixture deposition to investigate hot corrosion.
abstract: A hot corrosion study via molten salt deposition and its interaction with creep/fatigue play a critical role in predicting the life of gas turbine engine components. To do systematic hot corrosion studies, deposition of molten salts on specimens should be uniform with good adherence. Thus, the present study describes an in-house developed spraying setup that produces uniform and reliable molten salt deposition in a repeatable fashion. The efficacy of the present method was illustrated by depositing 90 wt. % Na2SO4 + 5 wt. % NaCl + 5 wt. % NaVO3 salt mixture on hot corrosion coupons and on creep specimens, and also by comparing with other deposition methods.
