Abstract
ABSTRACTCeramic thermal barrier coatings are being used in oil and gas industries, gas turbines and diesel engines. An atmospheric plasma spraying process is used to coat the ceramics on stainless steel grade 304 substrates. The salt spray (fog) test procedure was used to assess the corrosion resistance of ceramic-coated specimens. The coatings with ceria and without ceria on yttria-stabilised zirconia were compared for corrosion resistance. The commencement of red dust and the amount of weight loss of the coated specimens were related to time. The results indicated that the ceria mixed yttria-stabilised zirconia showed a better corrosion resistance.
