Abstract
Solution precursor plasma spray SPPS can synthesize powders and deposit the coatings synchronously The lanthanum zirconate coatings are deposited by SPPS in the present study and the dense coating can be obtained through changing the precursor solution The addition of urea can change the heat exchange process for some precursor mixtures However almost no effect can be found on the microstructure of powder and coating by the addition of urea The extra heat energy caused by the addition of urea is so small as compared with the heat input by the present plasma jet so that the heating effect can be ignored The porosity of coatings increase when the LaCl3·7H2O instead of LaNO33·6H2O reacts with ZrCH3CO24The authors thank Mr Tiegang Li from the University of Toronto for assistance with the plasma spraying experiments Dr Weize Wang gratefully appreciates the support of the National Natural Science Foundation No 51275172 and the National Program on Key Basic Research Project No 2012CB625104
